In 2014 the Nor-Fishing Foundation established the Nor-Fishing Foundation Travel Award, which enables one person from the developing world to visit Aqua Nor or Nor-Fishing, an important national and international meeting place to get updated on innovation and technology in the fisheries industry.
The Travel Award covers the cost of air travel from the winner’s home to Trondheim, where the selected candidate will spend a week as a guest of the Nor-Fishing Foundation, including hotel accommodation and some spending money. The winner will also be invited to the main events during the exhibition where he can make contact with a wide network of experts.
The successful candidate should be involved in aquaculture in some way, either as a fish farmer, educator, senior public official, or similar. The winner will be expected to write reports about the experience and to promote Aqua Nor in a general way after returning to the home country.
The deadline for the application is 1 June 2015 and the winner will be announced by the end of June 2015.
Aqua Nor will take place in Trondheim, Norway, 18-21 August 2015.

NOAA has approved a sector exemption request from the Gloucester Fishing Community Preservation Fund (GFCPF), which will utilize the sector system to preserve 30 metric tons of cod in exchange for relaxing some of the Gulf of Maine cod Interim Management Measures enacted in November 2014.
The popular demand for flexible packaging materials such as plastic films and vacuum pouches is seen among consumers and retailers alike. Many retail companies enter into partnerships with these packaging companies to preserve the quality and taste of food products in retails shops and increases the product visibility.
A JRC-organised session on coastal and marine ecosystem services generated a lot of interest and positive feedback from the participants at last month’s annual Association of the Sciences of Limnology & Oceanography (ASLO) 2015 meeting in Granada, Spain.
This year’s ASLO meeting, the theme of which was “Aquatic Sciences: Global And Regional Perspectives — North Meets South”, was attended by more than 5 000 scientists from all over the world.
There was standing room only at the JRC-organised session, entitled “Bridging the gap between ecosystem modelling and ecosystem services’ assessment in coastal and marine waters”. The JRC chaired the session and made two of the six presentations, which were complemented by sessions from French, Spanish and US research organisations. The session was very well received and generated lively discussions among the attendees.
The oceans and the coastal zones are considered to be the largest contributors to the total economic value of the biosphere through ecosystem services such as the provision of fish, water purification, carbon sequestration and recreation. However, the modelling and quantification of these services is relatively limited compared to terrestrial assessments. Ecosystem modelling assesses the structure and functioning of marine and coastal ecosystems, and is therefore a very suitable tool for assessing the related ecosystem services.
It is hoped that the improved assessment of coastal and marine ecosystem services will help raise awareness about the inherent value of the biosphere, and put a halt to the further degradation/destruction of this natural capital.

Food security will remain a significant issue for the Arab countries due to supply uncertainty and a growing population.
The Arab countries have to import more than half of their food commodities under conditions and the rising level of food prices for their imports. Such a rise in prices, especially in the poorer countries have pushed prices of food commodities, including seafood products, preventing the largest sections of the populations in several Arab countries to face extreme difficulties in feeding themselves.
- Distribution and marketing system cannot cope during glut periods,
- Physical loss from discarding of bycatch,
- Absence or shortage of cold storage facilities,
- About 25% of catch is processed into fish meal or oil.
Solutions to reduce post-harvest losses include:
- Wiser use of resources by reducing spoilage and discards,
- Converting low-value resources into products for human consumption,
- Improved fish handling on-board and on-land, processing, preservation and transportation,
- With more fish scarcity, discards and bycatch may become more commercially desirable.
2.Better utilization of by-catch:
The increasing demand for fish and fishery products prompt countries to consider ways to further utilize available resources capable of contributing to human food supplies. The fuller utilization of fishery resources, especially with regard to the utilization of products now being discarded as reject catches or as wasted by-products, is receiving increased attention worldwide. It is estimated that in some fisheries, especially shrimp fisheries in the Arabian Gulf area, has been estimated to be over 50 percent of the total catch. Options for by-catch utilization include the reduction of untargeted species by using exclusion devices (BRD) to allow fish to mature and be harvested as food fish and the recovery of by-catch and its handling on board or on shore.
5. Range of seafood products suitable for direct human consumption:
- Some of these products may be prepared as required by the local markets either breaded, marinated, buttered, seasoned, spiced, sauced, etc. and
- Any of the above products which may not be marketable locally may find markets abroad after packaging in attractive consumer pack coupled with an effective marketing strategy.
- Utilization of waste from tuna, small and large pelagic species, sharks and seashells.
Several countries in the NENA region catch several species of tuna, sardines; mackerel and anchovies. Canning plants normally utilize the main product and discard the offal as waste. The resulting left-overs may also be used to make other productsfor human consumption, for export and local markets or for fish meal.
- Waste from shrimp range from 50-70 % of whole shrimp. Valuable waste is produced from peeling and heading which can be used to generate extra income;
- Shrimp meal is used in aquaculture and in poultry feed to produce deep colored egg yolks which is important for sustainability;
- Chitin/chitosan, available in the shrimp heads, skeleton and shells, may be used in poultry feed to increase weight by 12 %;
- As a chemical, it inhibit fungal infestation of plants, in recycling water and for several medical uses; and
- It is non-allergic, harmless and has great potential in external and internal surgery applications.
7. Range of products from waste and losses not suitable for human consumption
- Fish skins, scales, undesired small bony fishes; waste from crustacean; waste from canneries of small and large pelagic species; jelly fish, shark parts, seashells and other offal;
- Undesired products for direct human consumption may be converted into various other products which generate extra income for fishermen, farmers, processers and traders; and
- These products include pet and livestock feed, industrial and pharmaceutical products that could be manufactured from bycatch, by-products and waste.
Fish Scales are about 4-10 % of fish. It is a major component of fish processing waste and often discarded with other fish waste. Scales also has some potential uses:
- Scales may be used for heavy metal removal and and as coagulant for the recovery of protein pigments from waste water;
- Preparing high value products including protein bars, cereal bars, protein drinks, smoothies, and joint health and pharmaceutical products;
- Food supplement to improve low bone mineral density in malnutrition and joint diseases;
Fish scales are used as raw material in collagen-based products such as skin moisturizers, anti-aging creams, wrinkle removers, hand creams, cleaning gels, Botox knock-offs and are safe to humans. Fish scales are used in cosmetics, decorations, jewelry making and ornamentation.
- After consuming the meat, skins are saved, cleaned with detergents and turned into various products;
- These include boots, mittens, bags, parkas, shoes, purses; hats, belts, garments in several colors for human use;
- Authentic, genuine fish leather are recycled from skins of fish such as carp, perch, seabass, tilapia and salmon;
- Major brands such as Prada, Gucci, Ferragamo, Dior; Nike and Puma use fish leather; and
- They are also suitable for bookbinding, jewelry making and several other uses.
9. Utilization of by-products as fish meal, fish silage for pet , poultry and livestock feed Small boney fish caught in trawls and other trash fish and offal from processing that are not suitable for human consumption could find other uses :
- Main utilization of such waste should be milled into manufacturing fish meal mainly for aquaculture;
- Arab region markets for pet foods such as cats, dogs, birds, and aquatic pets etc. is growing and will help generate extra income; and
- Production of livestock and poultry is increasing. Some countries utilize dried fish for animal feed due to its high protein content.
10. Pet and livestock feed & fish meal and Oil from fish by-products
In terms of added-value from fish waste, the least attractive means of by-product utilization is as a fertilizer.
- Some Arab countries try to develop an arable agricultural industry;
- Second to irrigation, important fertilizers are the main cost constraint;
- Large quantities of sun-dried fish are used as soil conditioners which is a good outlet for bycatch to sun dry unmarketable fish for fertilizers;
- Fish fertilizers provide an excellent source of nutrition for plants and the soil; and Fish fertilizers also help improve microorganisms in the soil and help increase crop growth and microbial activity.
- Arab countries has a rapidly growing population which could reach 604 million people by 2050;
- In addition to supplies of seafood, better utilization of bycatch, by-products and waste from post-harvest activities increases market supplies and generate extra income for fishermen, fish farmers, processers and traders;
- Less bycatch means less time for sorting through target catch and the targeted catch would keep better quality and price;
- In order to increase supplies, a comprehensive approach required for proper handling, processing and marketing techniques and product(s) development;
- Better utilization of resulting by-products contributes to extra food supplies for human consumption and income as well as for other useful industrial uses; and
- Public and private initiatives are needed for improvements in utilizing bycatch and waste mainly in the small-scale sector as well as the planned aquaculture projects planned by several Arab countries.
The above set of measures may be taken, in part or in whole, by Arab fisheries companies and responsible institutions and the private sector which are responsible for producing more fish domestically, in order to reach better and more sustainable growth in fish production. These measures may be to not only increase fish and fishery products on the markets as a means of reducing or controlling the rise in prices but also may help reduce imports thus preserving hard currencies especially for Arab countries that are pressed for foreign exchange.

Egypt’s plan to expand the Suez Canal threatens the sea’s fragile biodiversity.
The Mediterranean Sea is among the world’s great environmental jewels. The sea is highly saline, almost entirely enclosed by land and contains immense biodiversity. Scientists have long worried that its health is imperiled. Swelling coastal populations and ship traffic have brought overfishing and pollution. Climate change threatens to roil the waters still further.
One threat that is now gaining particular attention: the arrival of invasive species. One of the Mediterranean’s few outlets is the 146-year-old Suez Canal, which links it to the Red Sea and the ocean beyond. This creates a vital shipping route between Europe and Asia. But scientists fear that an expansion of the canal could bring more invasive species to the Mediterranean’s fragile waters.
Last year, Egypt announced plans to quickly build 45 more miles of waterway — a parallel canal, in part — so that ships can pass through more quickly than they do now. With the existing canal, they often must wait because the channel is narrow — about 1,000 feet wide at its slimmest point.
Because of the Suez and its expansion, the Mediterranean Sea’s problem with invasive species is becoming “worse than anywhere else on earth,” said Bella Galil, a senior scientist with Israel’s National Institute of Oceanography.
Among the unpopular arrivals are venomous jellyfish, which have unnerved tourists and sometimes obstructed water intakes belonging to electric-power or desalination plants, in addition to harming the natural ecology. Another worrisome invader is the puffer fish, sometimes known as the silver-cheeked toadfish, which releases a neurotoxin that can harm other fish and humans who consume it.
The existing Suez Canal has already served as a conduit. Invasive species are particularly concentrated in the eastern part of the Mediterranean, in the vicinity of the Suez Canal. The canal is already seen as “as one of the most significant pathways of marine invasions globally,” and it has ushered more than 350 nonnative species — including the puffer fish — into the Mediterranean, according to a letter sent in December from Julia Marton-Lefèvre, then director general of the International Union for Conservation of Nature, to Karmenu Vella, the European commissioner in charge of the environment, maritime affairs and fisheries.
Dr. Galil said, “Marine invasions are forever,” because it is impossible to remove an invasive species from the sea after it has arrived. The sea and its complex food web, she added, are “teetering.”
Some invasive species hitch rides in the ballast water of ships, an issue that the International Maritime Organization is trying to address through new rules regarding the treatment of ballast water to remove stowaways. Others cling to ship hulls, but many creatures simply swim through the Suez Canal itself.
“The expansion of the Suez Canal (enlarging, deepening) will make the environment within the canal more stable and thus will be easier to new species to cross it and invade potentially the Mediterranean,” Michel Bariche, an expert on Mediterranean marine issues at the American University of Beirut in Lebanon, said in an email.
Once they arrive, successful invasive species often outcompete natives, he said, because they tend to be more efficient at basic functions like obtaining food or reproducing.
Backers of the canal expansion cite strong economic opportunities. José Herrera, the parliamentary secretary for competitiveness and economic growth for the island nation of Malta, said that he expected the Suez expansion to benefit the Mediterranean region. “Having more traffic per se does not necessarily mean adverse effects,” he said. Malta, which lies along the major shipping lane through the sea between Europe and Asia, has been working to expand as a hub for shipping and logistics.
“Economic growth should always be promoted, but in sustainable ways,” Mr. Herrera said.
Dr. Galil said that the Suez project could learn from a similar expansion that is underway for the Panama Canal, which was built more than a century ago. The Panama Canal, she said, included an environmental impact assessment process that scientists participated in, and measures are in place to help prevent alien species from crossing between the Pacific and the Atlantic oceans.
“From a bio-invasion point of view, the Panama Canal is well run,” she said, noting that locks help prevent water transfers between the two oceans.
A study ( http://onlinelibrary.wiley.com/doi/10.1111/ddi.12260/pdf ) last fall in the journal Diversity and Distributions, however, has raised some concerns about increased opportunities for invasive species following the Panama Canal expansion.
But plans for the Suez continue unabated. Egypt is proceeding quickly with the expansion and has said, ambitiously, that it hopes to be done later this year.
The European Union is in touch with the Egyptian government about its plans, and watching closely. The environment, maritime affairs and fisheries arm of the European Commission is aware of the invasive species concerns, and has information suggesting that an environmental impact assessment is being carried out, according to Enrico Brivio, a spokesman.
Solutions to the invasive species problem could include the establishment of a barrier of salty water, in combination with locks, that would discourage some species from swimming through to the Mediterranean.
The invasive species issues come atop other, mounting problems affecting the Mediterranean, such as overfishing and climate change. Because the Mediterranean is enclosed almost entirely by land, climate change especially could be tough on native species.
“It means that species that might change their distribution and move farther north have an upper boundary,” said Catherine Longo, a project scientist with the Marine Science Institute at the University of California, Santa Barbara.
