Eroded swimmeret syndrome, a novel disease of the signal crayfish - University of Eastern Finland

Eroded swimmeret syndrome, a novel disease of the signal crayfish - University of Eastern Finland | Aquaculture Directory | Scoop.it

Crayfish researchers at the University of Eastern Finland Department of Biology have discovered, together with Swedish colleagues, a new disease plaguing female signal crayfish. As the name suggests, eroded swimmeret syndrome (ESS) destroys the swimmerets of female crayfish, weakens their reproductive ability and can increase the mortality of mother crayfish. In Finland and Sweden, the observed declines and sudden plunges in natural populations of signal crayfish can, to some extent, be explained by eroded swimmeret syndrome.

SYMPTOMS CAUSED BY A FUNGUS

For a couple of years now, eroded swimmeret syndrome has been observed in female signal crayfish in both Finland and Sweden. Over the past year, the syndrome has been a target of intense research, and it has been discovered that female signal crayfish weakened by crayfish plague can contract eroded swimmeret syndrome. Molecular biological studies show that the erosion of the swimmerets and the actual symptoms are caused by a fungus of the Fusarium genus.

Prebiotics as immunostimulants in aquaculture: A review

Prebiotics as immunostimulants in aquaculture: A review | Aquaculture Directory | Scoop.it

Fish & Shellfish Immunology 40 (1) 40-48

 

Prebiotics are indigestible fibers that increase beneficial gut commensal bacteria resulting in improvements of the host's health. The beneficial effects of prebiotics are due to the byproducts generated from their fermentation by gut commensal bacteria. In this review, the direct effects of prebiotics on the innate immune system of fish are discussed. Prebiotics, such as fructooligosaccharide, mannanoligosaccharide, inulin, or β-glucan, are called immunosaccharides. They directly enhance innate immune responses including: phagocytic activation, neutrophil activation, activation of the alternative complement system, increased lysozyme activity, and more. Immunosaccharides directly activate the innate immune system by interacting with pattern recognition receptors (PRR) expressed on innate immune cells. They can also associate with microbe associated molecular patterns (MAMPs) to activate innate immune cells. However, the underlying mechanisms involved in innate immune cell activation need to be further explored. Many studies have indicated that immunosaccharides are beneficial to both finfish and shellfish.

Safeguarding the future of our seas, generating new prosperity

 

Seas and oceans are essential to human life in more ways than one. They regulate our climate and through the centuries have given us food, transport and recreation. Now, thanks to technological progress, they can also give us pharmaceuticals, minerals and possibly infinite energy — as long as our exploitation is responsible, our methods are safe and our trading is cautious and fair. Equally crucial is the economic value of the sea in our society.

 

The European Commission works to ensure that our exploitation remains rigorously sustainable and the rich maritime heritage of Europe grows nonetheless. The premise is that the two — environmental protection and economic growth — are intertwined and interdependent rather than opposed. This publication is a part of a series that explains what the EU does in different policy areas, why the EU is involved and what the results are...

PORTUGAL: Scientists produce sun protection from recycled fish bones

PORTUGAL: Scientists produce sun protection from recycled fish bones | Aquaculture Directory | Scoop.it

PORTO  - A team of researchers at Portuguese Catholic University in Porto has developed an effective new sunscreen derived from recycled cod fish bones.

 

Portugal scientists have made the new sunscreen by treating cod bones with FeCl2solution for three hours at 65-70 øC, Press TV reported.

 

"They then dried the bones overnight and calcined at 700 øC for one hour, yielding multiphasic materials containing HAp, iron-substituted HAp and a small amount of hematite that absorbs UV radiation," explained Clara Piccirillo from the Portuguese Catholic University.

 

"Iron oxide was already reported as a UV absorber; in our material, the presence of calcium iron hydrogen phosphate (Ca9FeH(PO4)7) increases the absorption and extends it over the whole UV range," Piccirillo also noted.

 

In next step the prepared materials were made into creams.  Various tests revealed the good photostability and a UVA-to-UVB ratio even greater than 0.90, which means that the production has proved to be a comparable protection against both UVA and UVB radiation.

 

The naturally derived sunscreen was tested on 20 human volunteers who had a small quantity of the cream applied to an area of their skin for 48 hours and showed no adverse allergic reaction.

ICELAND: Fish catch in June has increased between years | Aquaculture Directory | Scoop.it

The total catch of Icelandic vessels was 40% higher in June 2014 than in June 2013. Most of the demersal catches increased as well as landing of Blue whiting.

 

When 12 month periods are compared between years we see a 21.2% decrease in catch between July 2013 and June 2014 when compared to the same period one year earlier. For the same 12 month periods there was a decrease of 3.4% in fish catch at constant price when compared to the same period one year earlier.

ΕΛΛΑΔΑ: Τι... ΔΕΝ είπε χθες ο Γιάννης Στεφανής

ΕΛΛΑΔΑ: Τι... ΔΕΝ είπε χθες ο Γιάννης Στεφανής | Aquaculture Directory | Scoop.it

Αξιοσημείωτη η χθεσινή παρέμβαση του διευθύνοντος συμβούλου των Ιχθυοτροφείων Σελόντα κ. Γιάννη Στεφανή, με στόχο την ενημέρωση των μετόχων. Τώρα γιατί συχνά χρησιμοποίησε ξένους όρους και μάλιστα με αρκτικόλεξα(!) είναι ένα άλλο θέμα.

 

Αναφέρθηκε λοιπόν σε μια σειρά κινήσεων που η εταιρεία του έκανε κατά τα τελευταία χρόνια. «Χωρίς κομπασμούς και μεγαλοστομίες δίνουμε δείγμα γραφής για την αναδιάρθρωση του κλάδου και όχι μόνο».

 

Επίσης, σημείωσε πως «πιστεύω ότι όλοι οι εμπλεκόμενοι έχουν πλέον συνειδητοποιήσει ότι η κρισιμότητα της κατάστασης και η σημασία του κλάδου δεν επιτρέπουν μικροψυχίες», γι αυτό και έχουν αρχίσει να προετοιμάζονται μια σειρά από διαθέσιμες μεθόδους-εργαλεία.

 

Και τέλος, δήλωσε πως οι τράπεζες διαθέτουν πλέον «αξιόλογη γνώση των τεκταινομένων» και ότι «η Σελόντα, σαν ήρεμη, αξιόπιστη και συνεπής δύναμη υποσχέθηκε στο τραπεζικό σύστημα ότι θα συμπαρασταθεί ενεργά στην αναδιάρθρωση του τόσο σημαντικού κλάδου και το έκανε πράξη, χωρίς ναι μεν αλλά».

 

Εμείς δεν έχουμε λόγο να αμφισβητήσουμε τίποτε από τα παραπάνω, ωστόσο στην παρέμβασή του ο κ. Στεφανής, δεν αναφέρθηκε σε μια σειρά από πράγματα, όπως:

 

Πρώτον, αναδιαρθρώσεις γίνονται συνήθως όταν μια επιχείρηση δεν πάει καλά. Ο κ. Στεφανής λοιπόν δεν εξήγησε το γιατί η εταιρεία του βρέθηκε με αρνητικά ίδια κεφάλαια και σε αδυναμία να αποπληρώσει τις υποχρεώσεις της. Ευθύνεται η διοίκηση της εισηγμένης εταιρείας (ο ίδιος δηλαδή) και κατά πόσο;

 

Δεύτερον, ανέφερε για το Linnaeus Fund ότι «σπατάλησε σημαντικούς πόρους (65 εκατ. ευρώ) ενός σωστού οράματος με λάθος τρόπο. Η στρατηγική και οι τακτικές κινήσεις που ακολούθησε δημιούργησαν πολλές αντιθέσεις». Προφανώς το Linnaeus Fund έχασε πολλά λεφτά, ωστόσο σημαντικό ποσοστό των χαμένων κεφαλαίων του, το «σπατάλησε» στην αγορά μετοχών Ιχθυοτροφείων Σελόντα, της οποίας ο ίδιος ο κ. Στεφανής ήταν βασικός μέτοχος και διευθύνων σύμβουλος.

 

Και τέλος, ο κ. Στεφανής δεν απάντησε στο γιατί το management της προβληματικής εταιρείας του εισπράττει «αμοιβές golden boys», τώρα που -όπως δηλώνει- «ο αντίπαλος πρέπει να είναι πλέον η Τουρκία και η διείσδυσή της στις αγορές»...

Fish hospital to come up at Thevara

Fish hospital to come up at Thevara | Aquaculture Directory | Scoop.it

KOCHI: The city is gearing up to set up the first aquatic animal hospital in the government sector. An Aquatic Animal Health and Environment Management Laboratory will come up on the premises of the Fishermen Training Centre at Thevara under the  Agency for Development of Aquaculture, Kerala (ADAK). The state government has accorded sanction for `1.12 cr for it. The total amount for the project is `1.68cr, the rest of the amount will be provided by National Fisheries Development Board. The construction work will be carried out by Ernakulam Nirmithi Kendra which is expected to begin soon.

“The centre is envisaged as a virtual research and support centre for fish farmers and as a ‘Hospital for Fish’ to address various diseases cropping up in fish species, which are being reported seasonally from various parts of the country. The hospital will be able to regularly monitor the occurrence of diseases and evolve effective strategies for health management for aqua culturists. The lab will also play an important role in quarantine and disease-free certification of ornamental fish,” sources said.  

The laboratory will act as a support component for all hatcheries and farms both in the government and private sector to test the quality of fish seed.

Experts pointed out that since the significance of aquaculture is rapidly increasing in the state, the establishment of such a laboratory is relevant. It is estimated that around 400 aquaculture farmers across the state will be benefited from the facility.

The laboratory will function as a monitoring and surveillance centre for diseases affecting fishes and aquatic organisms, including shrimps, fresh water prawn and farming fishes. The centre will be able to test the pollution levels of water. It will maintain registers pertaining to the details of farmers, samples given for testing, tests undertaken and results. These can be used for further aquaculture research, sources said.

SPAIN: Sea urchin embryos managed to be frozen for toxicity studies

SPAIN: Sea urchin embryos managed to be frozen for toxicity studies | Aquaculture Directory | Scoop.it

A team of researchers from the University of Vigo (UV) has established the first protocol for cryopreservation of sea urchin embryos to be used in the detection of contaminants and in the field of aquaculture.

 

Cryopreservation makes it possible to maintain biological materials at very low temperatures but its use in the marine environment is still very low in the world.

 

Marine Ecotoxicology group of the UV uses sea urchin embryos in bioassays to detect the presence of contaminants but one of the constraints being faced is the seasonal variability of the resource.

 

"Hopefully, we have them for five months a year," explains Estefanía Paredes, whose doctoral thesis focuses on the cryopreservation method developed.


Hence the importance of having a cryobanking cells, adds the expert in Marine Sciences.

 

Paredes travelled to New Zealand twice and in the Cawthron Institute became acquainted with the cryopreservation techniques used by the group of the expert Serean Adams with the New Zealand mussel (Perna canaliculus) and the oyster (Crassostrea gigas).

 

The PhD student decided to include both species in her project as well as the Galician mussel (Mytilus galloprovincialis), the newspaper La Opinión reported.

 

Besides, she travelled to the United States and at the University of Tennessee she worked with Peter Mazur, a pioneer in embryo freezing.

Mazur's lab achieved the first successful cryopreservation of mouse embryos in the 70s.

 

Paredes explains the cryopreservation of the four species selected is performed in the early stages, namely, during the trochophore larva stage, which appears at 14-16 hours after the embryo is formed.

 

As with the sea urchin the Spanish group started from scratch, it really did not know how their larvae could be cryopreserved.

 

According to Paredes, it is a process that is "really elaborate and delicate," in which the most critical elements are the cryoprotectants and freezing rates. 

 

"The cryoprotectants are like the antifreeze from a car and it allows the cells to slowly dehydrate until they freeze without forming ice inside, causing their death," the expert continued explaining.

 

Since there is also the danger that the antifreeze intoxicates the larvae so its choice requires great care.

 

As to the freezing rate, this "determines how many degrees per minute the temperature can be made to go down for the dehydration process to take place under suitable conditions."

 

When the embryos are frozen, they are submerged in liquid nitrogen at almost 200 °C. If the process has been successful, when the embryos are thawed, they are reactivated gradually.

 

The researcher set a portable cryo-chamber that allowed her to perform her studies in the laboratories of the campus and the Marine Science Station in Toralla (ECIMAT).

 

The biologist compared the results of the bioassays performed with fresh larvae with those that were frozen, and concluded that the frozen ones can offer the same reliability in the detection of organic pollutants and heavy metals in seawater.
