WORLDWIDE: Report notes decline in shark fin trade while another endangered species suffer

WORLDWIDE: Report notes decline in shark fin trade while another endangered species suffer | Aquaculture and Fisheries - World Briefing | Scoop.it

While shark’s fin soup has long been a revered delicacy for the Chinese, trade in shark has recently declined, notes a new study from WorldFish scientist Hampus Eriksson and shark trade expert Shelley Clarke from the Australian National Centre for Ocean Resources and Security. The study also reports that while there is growing conservation momentum for shark, the trade in sea cucumber, another high-value Chinese delicacy, has not diminished. Seven species in this group of animals are now endangered due to overfishing.

 

Sea cucumber is the second most valuable seafood export from the Pacific Islands after tuna. However, unlike tuna fishing, which requires considerable investment in vessels and gears, sea cucumber harvesting can be done with minimal equipment, such as a bucket. Therefore, sea cucumber harvesting provides an important source of  livelihoods for poor and vulnerable communities.

 

The report’s authors note that current regulatory environments are insufficient to safeguard sea cucumbers and recommend strengthened conservation strategies. Proper governance of fisheries and supply chains will be necessary to make sure that sea cucumbers are harvested sustainably and fishers livelihoods are not negatively impacted.

 

Stephen J Hall, Director General, WorldFish: “We must achieve a balance between conservation and the livelihoods of those that depend on this valuable resource. Improved trade monitoring systems will greatly assist in guiding appropriate management responses. In parallel we should also put greater effort into understanding the potential of aquaculture to reduce the pressure on wild caught sea cucumber.”

 

Scientists note that sea cucumber plays a vital role in the recycling of nutrients that can, in turn, feed algae and coral. Some believe that they may also play a role in reducing coral damage due to ocean acidification.

 

Part of the challenge is better understanding how global supply chains can be governed in ways that support equitable distribution of benefits to fishers and under what management models this can be achieved.

 

Chinese market responses to overexploitation of sharks and sea cucumbers also discusses how the Chinese seafood market for these products has adapted to compensate for declining wild catch stocks. For sea cucumbers, aquaculture is now a major contributor towards maintaining overall production in the face of overfished wild resources. A Chinese government led campaign against consumption of shark fin soup combined with mounting global concern has reduced trade the report concludes.

RESEARCH ARTICLE: Harvesting effects and recovery mechanisms of red coral Corallium rubrum

RESEARCH ARTICLE: Harvesting effects and recovery mechanisms of red coral Corallium rubrum | Aquaculture and Fisheries - World Briefing | Scoop.it

Abstract

 

Overexploitation is a major threat for the integrity of marine ecosystems. Understanding the ecological consequences of different extractive practices and the mechanisms underlying the recovery of populations is essential to ensure sustainable management plans. Precious corals are long-lived structural invertebrates, historically overfished, and their conservation is currently a worldwide concern. However, the processes underlying their recovery are poorly known. Here, we examined harvesting effects and recovery mechanisms of red coral Corallium rubrum by analyzing long-term photographic series taken on two populations that were harvested. We compared the relative importance of reproduction and re-growth as drivers of resilience.

 

Harvesting heavily impacted coral populations causing large decreases in biomass and strong size-class distribution shifts towards populations dominated by small colonies. At the end of the study (after 4 and 7 years) only partial recovery was observed. The observed general pattern of low recruitment and high mortality of new recruits demonstrated limited effects of reproduction on population recovery. Adversely, low mortality of partially harvested adults and a large proportion of colonies showing new branches highlighted the importance of re-growth in the recovery process. The demographic projections obtained through stochastic models confirmed that the recovery rates of C. rubrum can be strongly modulated depending on harvesting procedures.

 

Thus, leaving the basal section of the colonies when harvesting to avoid total mortality largely enhances the resilience of C. rubrum populations and quickens their recovery. On the other hand, the high survival of harvested colonies and the significant biomass reduction indicated that abundance may not be an adequate metric to assess the conservation status of clonal organisms because it can underestimate harvesting effects. This study highlights the unsustainability of current harvesting practices of C. rubrum and provides urgently needed data to improve management practices that are still largely based on untested assumptions.

ΕΥΡΩΠΑΪΚΗ ΕΝΩΣΗ: «Ακτινογραφία» του ελληνικού αλιευτικού στόλου

ΕΥΡΩΠΑΪΚΗ ΕΝΩΣΗ: «Ακτινογραφία» του ελληνικού αλιευτικού στόλου | Aquaculture and Fisheries - World Briefing | Scoop.it

«Ακτινογραφία» του ελληνικού αλιευτικού στόλου γίνεται στην έκδοση του 2014 με στατιστικά για την Γεωργία- Δασοκομία & Αλιεία της ΕΕ, η οποία δόθηκε, την Παρασκευή 20/2, στην δημοσιότητα.

Ειδικότερα, από τα στοιχεία για την Αλιεία φαίνεται ότι ο αλιευτικός στόλος της ΕΕ καταγράφει μια αρκετά σταθερή μείωση από τις αρχές της δεκαετίας του 1990 τόσο από πλευράς χωρητικότητας (ένας δείκτης ανάμεσα σε ψάρια και εκμετάλλευση) και της ισχύος του κινητήρα (ένας δείκτης της δυναμικότητας των διαθέσιμων αλιευτικών εργαλείων).

Συγκεκριμένα, το μέγεθος του αλιευτικού στόλου της ΕΕ στόλος έχει μειωθεί σε περίπου 86.500 σκάφη το 2013 σε σύγκριση με τα 104.000 σκάφη για την ΕΕ των 15 το 1995, αν και αυξήθηκε κατά 7,2% μεταξύ του 2012 και του 2013, μετά την ένταξη της Κροατίας στην ΕΕ.

Σχεδόν το ένα πέμπτο (18,3%) του αλιευτικού στόλου της ΕΕ-28, που αντιστοιχούν σε 15.970 σκάφη  είναι νηολογημένα στην Ελλάδα. Κατά μέσο όρο, όμως, αυτά τα ελληνικά σκάφη είναι μικρά, με μέσο μέγεθος 4.9 κόρων (πολύ λιγότερο από ό, τι  ο μέσος όρος  της ΕΕ-28, που είναι 19,2 κόροι) και μέση ισχύ του κινητήρα των 28,9 κιλοβάτ το 2013 (σε σύγκριση με τον μέσο όρο της ΕΕ-28 των 76,0 κιλοβάτ).

Όσον αφορά την ικανότητα της Ισπανίας, της Γαλλίας, της Ιταλίας και το Ηνωμένο Βασίλειο έχουν τους μεγαλύτερους αλιευτικούς στόλους, αντιπροσωπεύοντας το 54,2%  της ολικής χωρητικότητας και το 55,8% της ισχύος του κινητήρα το 2013.

Ο ελληνικός αλιευτικός στόλος έχει ακολουθήσει την γενικότερη τάση της μείωσης με αποτέλεσμα από 20.598 σκάφη, που αριθμούσε το 1995 μειώθηκε το 2013 σε 15.970 επί συνόλου στην ΕΕ 86.479 σκαφών.

Η αλιευτική παραγωγή του ελληνικού στόλου το 2012 έφτασε τους 173.000 τόνους ενώ η Ισπανία, που έχει λιγότερα αλλά πολύ μεγαλύτερα σκάφη, είχε ετήσια παραγωγή άνω του ενός εκατομμυρίου τόνων και έπεται η Αγγλία με 832.000 τόνους.

Οι ευρωπαϊκές «υπερδυνάμεις» της αλιείας, η Νορβηγία και η Ισλανδία είχαν ετήσια παραγωγή 3,3 εκατομμυρίων τόνων και 1,4 εκατομμυρίου τόνου, αντίστοιχα.

Τέλος, θα πρέπει να σημειωθεί ότι ο ελληνικός στόλος περιορίζει την δραστηριότητά του στη Μεσόγειο, Αιγαίο και Ιόνιο, κατά κύριο λόγο, και μόνο ένας τόνος αλιευμάτων προήλθε από τον Ανατολικό Ατλαντικό, όπου κυριαρχούν Ισπανοί, Άγγλοι και Βορειοευρωπαίοι ενώ Ισπανοί ψαρεύουν σημαντικές ποσότητες και στον Ινδικό ωκεανό.

NORWAY: Genomics to combat shrimp disease

NORWAY: Genomics to combat shrimp disease | Aquaculture and Fisheries - World Briefing | Scoop.it

Shrimp aquaculture is carried out in large parts of Asia and Latin America. White spot syndrome is one of the most serious diseases of farmed shrimp, and there is currently no effective way of combating this disease. Scientists have recently discovered markers for genes that determine how well black tiger shrimp resist the disease. They are now planning to look for the genes in the white shrimp.

 

If the markers are used to breed shrimp that are more resistant to the disease, problems caused by the disease in the shrimp aquaculture industry will be significantly reduced.

 

The virus that causes white spot disease (WSSV) is capable of killing all the shrimp in a pond within 10 days of infection. The disease can, on occasions, totally devastate shrimp aquaculture in a complete region. There are currently no treatments available to effectively prevent outbreaks of the disease.

 

Indian and Norwegian scientists have been looking for a preventative solution in the shrimp genes. They have collaborated in the search for gene markers, which are locations in the genome, that code for the level of immunity the shrimps have against the virus. Senior scientist at the Norwegian food research institute Nofima, Nicholas Robinson, believes the findings will have a large impact on future generations of shrimp:

“Now that these markers have been found in the tiger shrimp, it will be possible to select for higher immunity to the disease in the next generation by implementing what is known as ‘marker-assisted selection’ into an advanced breeding program. Since the generation time of the shrimp is short, we can expect a clear effect within a few years,” says Robinson.

 

The first gene markers in shrimp

 

This is the first extensive experiment in which genes markers related to disease have been found in shrimp.

The research has been carried out by Nofima and the Indian CIBA (Central Institute of Brackishwater Aquaculture), and financed by the Research Council of Norway and the Indian Department of Biotechnology.

In addition to finding markers for disease resistance in the black tiger shrimp, the scientists have also found markers for genes that determine sex. The gene markers for sex could assist hatcheries to produce exclusively female shrimp for distribution. Male shrimp are small and grow slowly, so the discovery of sex-determining markers can enable aquaculture personnel to produce healthier shrimp that grow more rapidly.

Finding the disease markers

The genetic code (DNA sequence) in the genes of various shrimp was analysed, as the scientists sought for the markers. Variation in the DNA sequence of nearly 4,000 genes was compared within large groups that had been exposed to the disease. The scientists were looking for correlations between the duration of survival of the shrimp after being infected and the genetic code in their genes. It was possible in this way to reveal nine gene markers that were associated with resistance to the disease. Some of these were present in, or close to, genes that are known to have a function related to immunity in fish.

 

The scientists are now planning to examine whether the same genes affect the resistance to white spot disease in white shrimp. This will be financed by the same sources, and new partners will be involved. White shrimp is also used in aquaculture in India and several Asian countries.

“We are now in the process of starting a project for the white shrimp with the same goals – to discover genetic tools that can reduce a disease that is widespread in shrimp aquaculture,” concludes Robinson.

RESEARCH ARTICLE: Beyond Symbiosis - Cleaner Shrimp Clean Up in Culture

RESEARCH ARTICLE: Beyond Symbiosis - Cleaner Shrimp Clean Up in Culture | Aquaculture and Fisheries - World Briefing | Scoop.it
Abstract 

Cleaner organisms exhibit a remarkable natural behaviour where they consume ectoparasites attached to “client” organisms. While this behaviour can be utilized as a natural method of parasitic disease control (or biocontrol), it is not known whether cleaner organisms can also limit reinfection from parasite eggs and larvae within the environment. Here we show that cleaner shrimp, Lysmata amboinensis, consume eggs and larvae of a harmful monogenean parasite, Neobenedenia sp., in aquaculture. Shrimp consumed parasite eggs under diurnal (63%) and nocturnal (14%) conditions as well as infectious larvae (oncomiracidia) diurnally (26%). Furthermore, we trialled the inclusion of cleaner shrimp for preventative parasite management of ornamental fish, Pseudanthias squamipinnis, and found shrimp reduced oncomiracidia infection success of host fish by half compared to controls (held without shrimp). Fish held without cleaner shrimp exhibited pigmentation changes as a result of infection, possibly indicative of a stress response. These results provide the first empirical evidence that cleaner organisms reduce parasite loads in the environment through non-symbiotic cleaning activities. Our research findings have relevance to aquaculture and the marine ornamental trade, where cleaner shrimp could be applied for prophylaxis and control of ectoparasite infections.

ΙΑΠΩΝΙΑ: Νέα διαρροή ραδιενέργειας εντοπίστηκε στη Φουκουσίμα

ΙΑΠΩΝΙΑ: Νέα διαρροή ραδιενέργειας εντοπίστηκε στη Φουκουσίμα | Aquaculture and Fisheries - World Briefing | Scoop.it

Αισθητήρες στο πυρηνικό εργοστάσιο της Φουκουσίμα εντόπισαν μια νέα διαρροή ραδιενεργών υδάτων στη θάλασσα, σύμφωνα με ανακοίνωση των υπευθύνων του σταθμού, στην οποία υπογραμμίζονται οι δυσκολίες της διαδικασίας παροπλισμού.

 

Η Εταιρεία Ηλεκτρικής Ενέργειας Τόκιο (TEPCO) δήλωσε ότι οι αισθητήρες σε ένα κοντινό κολπίσκο, ανίχνευσαν την Κυριακή το πρωί επίπεδα ραδιενεργούς μόλυνσης έως και 70 φορές μεγαλύτερα από τα ήδη υψηλά επίπεδα που παρατηρούνται εντός του σταθμού της Φουκουσίμα.

 

Έκτακτες επιθεωρήσεις των δεξαμενών αποθήκευσης πυρηνικών αποβλήτων δεν έδειξαν επιπλέον ανωμαλίες και διαρροές, ωστόσο οι αξιωματούχοι της TEPCO διέκοψαν προληπτικά κάθε διαρροή νερού στον Ειρηνικό Ωκεανό.

 

Τα επίπεδα μόλυνσης μειώθηκαν σταθερά καθ’ όλη τη διάρκεια της ημέρας, αλλά οι ίδιοι αισθητήρες εξακολουθούσαν να δείχνουν επίπεδα μόλυνσης 10 έως 20 φορές υψηλότερα από το συνηθισμένο. Ακόμα δεν είναι απολύτως σαφές τι προκάλεσε την αρχική διαρροή και τη σταδιακή μείωσή της, σύμφωνα με τους εκπροσώπους της TEPCO, οι οποίοι δήλωσαν πως δεν έχουν κανένα λόγο να πιστεύουν πως υπάρχει διαρροή στις κύριες δεξαμενές αποθήκευσης ραδιενεργών αποβλήτων.

 

Το τελευταίο επεισόδιο, ένα από τα πολλά που έχουν συμβεί στο σταθμό κατά τους τελευταίους μήνες, αντικατοπτρίζει τη δυσκολία του παροπλισμού του εργοστασίου, το οποίο ήταν το επίκεντρο του μεγάλου πυρηνικού ατυχήματος το Μάρτιο του 2011, μετά το φονικό σεισμό και το ακόλουθο γιγαντιαίο τσουνάμι.

 

Η TEPCO δεν έχει καταφέρει να αντιμετωπίσει αποτελεσματικά την αυξανόμενη ποσότητα του μολυσμένου νερού που χρησιμοποιήθηκε για την ψύξη των αντιδραστήρων και των καυσίμων στο εσωτερικό τους, και η οποία διατηρείται σε μεγάλες δεξαμενές αποθήκευσης στις εγκαταστάσεις του σταθμού. Την κατάσταση επιδεινώνει η συνεχής ροή υπογείων υδάτων από τα κοντινά βουνά, τα οποία ταξιδεύουν κάτω από το μολυσμένο έδαφος του σταθμού πριν καταλήξουν στον Ειρηνικό Ωκεανό.

WORLDWIDE: New fish drying technology boosts livelihoods in Ivorian towns

WORLDWIDE: New fish drying technology boosts livelihoods in Ivorian towns | Aquaculture and Fisheries - World Briefing | Scoop.it

Rome - A new and easy-to-assemble fish drying technology pioneered by FAO is helping to reduce health hazards, improve food safety and quality, improve working conditions and cut down food losses in West African fishing villages.

Smoked fish is a vital source of food and income for many African coastal communities. In Côte d'Ivoire, for example, an estimated 20-30 percent of local marine and freshwater catch is consumed in smoked form, according to FAO.

A popular protein alternative, smoked fish is preferred by locals because of its taste, its nutritional benefits, its competitive prices compared to other protein sources such as milk, meat and eggs, and its long shelf-life which ranges from 3-6 months.

However, traditional kilns widely used to prepare this popular food item do pose some concerns.

"Traditional smoking techniques often involve a massive burning of wood which leads to a variety of problems. For one, an exorbitant amount of CO2 is produced, so the kilns produce more greenhouse gas pollution than they should. Also, traditional smoking releases contaminants known as polycyclic aromatic hydrocarbons (PAHs), which are carcinogenic and hazardous to the human respiratory system," says Yvette Diei-Ouadi, a fishery industry expert at FAO.

Traditional techniques also leave higher amounts of tar particles on the final product, affecting taste and quality - making it much more difficult to sell.

The new FTT technology - consisting of a dual functioning oven and mechanical drier, which also can act as storage unit - is especially designed to help small-scale fish processors like those in Abobodoumé prepare and market safe, high-quality food.

A result of five years of design improvements, FTT makes it easy to upgrade traditional ovens and is capable of significantly slashing the carcinogenic contaminants produced during smoking. At the same time, the technology reduces the amount of fuel needed and provides a load capacity five times greater than traditional barrel ovens or twice the Chorkor kiln.

A boom with the FTT

"This is a system developed to address many aspects of fish smoking operations," says Ndiaye Oumoulkhaïry, who worked on the FTT design. "In the first place stands the safety aspect - to secure consumers' health and meet international food standards. Then there's reducing post-harvest losses, and also curbing the drudgery of fish processors who are now least exposed to the heat and smoke."

In Abobodoumé, for example, a village in Côte d'Ivoire, female fish processors took immediate liking to the new FTT additions. Among their favorites, a collection plate which traps dripping fish oils they can re-use for manufacturing soap or as cooking oil.

They are also glad to be breathing in far less contaminant-containing smoke.

Different varieties of vegetable materials can also be burned, instead of just wood or coal. Coconut shells and husks, maize or even millet cob are just as effective in smoking fish and place far less pressure on the environment.

Women at center stage

"We are extremely happy, because as of today, with the FTT, our conditions for smoking fish have changed," says Deborah Oulou, an Ivorian woman fish processor.

''We are now working under hygienic conditions," confirms Micheline Dion Somplehi, another woman fish processor in Abobodoumé. "The FTT-Thiaroye ensures less heat, burn and smoke exposure. Smoking operations do not pose risk anymore to the health of our eyes and of our respiratory system''.

Shorter processing times and reduced risk of burns or smoke-inhalation also mean these women can focus more time on their roles as mothers and caretakers.

Dion Somplehi says: "We have seen the advantage of saving time in fish smoking, and this is really important because in our communities, women are at the same time engaged in household chores - taking care of the children, working in the kitchen - while carrying out fish processing activities. We are even able to smoke in bad weather conditions."

Platform for success

The new technology is proving popular in other African fishing nations as well, and its use is starting to spread in Senegal, Côte d'Ivoire, Tanzania and Ghana.

Development organizations like the Netherlands-based SNV is encouraging the use of FTT technology in Ghana as a way for small-scale producers to gain access to such lucrative international markets.
