Salmon producers, retailers, scientists, environmental groups and others from throughout the world will meet in Chile in December to review new reports about two of the main impacts of salmon aquaculture production: chemical inputs and nutrient loading/carrying capacity. Information in the reports, it is said, will then be used to guide discussions about developing jointly acceptable global standards for salmon aquaculture. A discussion about the socioeconomic costs and benefits of...

An international team of researchers has demonstrated how Atlantic cod responded to past natural climate extremes. The new research could help in determining cods vulnerability to future global warming. With fishing pressures high and stock size low, there is already major concern over the current sustainability of cod and other fisheries. The new findings, published in the journal Proceedings of the Royal Society B, show that natural climate change has previously reduced the range of...

If you're depending on farmed salmon for your daily vitamin D quota, you might rethink your strategy. It's a healthy food, but it doesn't contain the bounty of vitamin D many nutritionists count on. New research shows that popular farmed salmon has only a quarter as much vitamin D as wild caught. Although wild salmon doesn't have quite enough vitamin D to meet new suggested medical guidelines, it's a much better bet. The USDA has long claimed that 3.5 ounces of salmon contains...

The King crab can now be eaten without removing the shell if it is handled and prepared right after moulting when the shell is completely soft. The shell and crab can then be consumed once the mouth, stomach, intestine and gills have been removed. Soft-shell crab is an exclusive product at Asian restaurants, and soft-shell crabs can achieve five times the price than the equivalent crab with a hard shell. Taste testing Soft-shell King crabs...

Scientists in northern Tasmania have found that barramundi grow more quickly when fed lupins rather than smaller fish like anchovies. Professor Chris Carter of the University of Tasmania's School of Aquaculture says the discovery could save the aquaculture industry millions of dollars in fish food costs, ABC News reported. "I've always liked lupin as a replacement; it's got really good nutritional properties," he said. "We've tried it in salmon and trout...

The abalone industry may in future not be limited to just six frenetic weeks every year. A more productive industry is promised with the development of a hybrid species, proven to grow up to thirty percent faster than the commercial varieties now being farmed. A hybrid between Greenlip and Brownlip abalone species has been developed by Bayside Pty Ltd and Mr Mark Allsopp, a PhD student at Curtin University of Technology’s Muresk Institute. The growth rates of this particular hybrid...

Strong and durable polyethylene film from Borouge, a leading provider of innovative, value creating plastics solutions, is helping Thailand’s shrimp and fish farmers with pond covers that last longer and require less maintenance. Film produced with Borstar Enhanced polyethylene is also proving a cost-effective alternative to traditional material, enabling the film converter to use half as much material to produce the same thickness of film that fish farmers need to cover and line their...

Food safety and the depletion of fish stocks will remain key challenges for Asian seafood producers, according to Rabobank International. Patric Vizzone, regional head for Asia food and agribusiness at Rabobank International, said the decline in wild fish populations in East Asia was a global concern. East Asia accounts for 45% or 41.7 million tonnes of the global wild catch and nearly 90% or 42.8 million tonnes of global aquaculture. East Asia, which includes China,...

In today’s world dominated by ‘fast food’, ‘fast money’, and ‘fast habits’, people have obviously taken for granted the quality and safety of the food they eat. What seemingly matters most is not the acceptable safety standards of the food we eat, but just to be able to go through the meal and live another day. Unknown to people, however, is that the quality and safety of the food they eat have been the subject of intensive studies and critique by concerned...

Producers of fishmeal and oil achieved the best profitability in the Norwegian fishing industry in 2006, Fiskeriforskning's annual profitability study of the Norwegian fishing industry shows. Stockfish production claimed second place last year. The annual Profitability Study shows the overall result for the Norwegian fishing industry in 2006 was similar to that for 2005. However, there are clear differences in profitability between the various sectors. Production of...

A Territory business has produced what is thought to be Australia's first commercial aquaculture harvest of mud crabs. The first 3 tonne batch of crabs are ready to sell, but farm owner Seow Hung Yong is waiting a few weeks to get the best price. Mr Yong and his family have invested more than $1 million in the Australia Aquaculture Farming NT venture, renovating a former prawn farm site near Channel Island, south of Darwin. Mr Yong came to the NT from Singapore three years...

Researchers at the Department of Primary Industries and Fisheries' Bribie Island Aquaculture Research Centre have designed a new system for housing cannibalistic crustaceans such as crabs, clawed lobsters and crayfish. The Self-cleaning Compartmentalised Aquaculture system pumps in new water and removes effluent water from compartments housing individual animals. Improvement to current technology The system overcomes many limitations of other designs...

Fiskeriforskning has implemented research on the storage of live whelks in different temperatures. The findings show the whelk is well suited to capture-based aquaculture. The whelk is a newcomer among species fished by the Norwegian coastal fleet. The fishing grounds are spread along the entire Norwegian coast, but the distance to the nearest land facility can be great. Capture-based aquaculture of the whelks prior to transportation is therefore necessary. However,...

INDIA - The Fisheries College and Research Institute has commenced commercial production of seeds of tiger shrimps on its Maritech Research Centre campus situated at Tharuvaikulam near here. The hatchery for the purpose was established recently on the MRC premises at a cost of Rs.45 lakh allocated to the FCRI by Indian Council of Agricultural Research (ICAR). The unit was equipped with a seawater pumping and filtration system, two High Density Poly Ethylene (HDPE) lined...

Salmon farmers are again using a toxic pesticide years after it was thought to have been phased out. The chemical, teflubenzuron, known commercially as Calicide, and is given to salmon to kill sea lice parasites. Concerns about the polluting effects of the substance, 90 per cent of which is excreted by the salmon into the sea, have been raised by shellfish farmers. A 1999 report by the Scottish Environment Protection Agency (Sepa) found teflubenzuron to be "potentially highly...

Fish powder is healthy, but it can become even healthier. A new research project will contribute to taking care of more of the fish's natural antioxidants. Fish powder is used in particular in the manufacture of health food products, but also as flavouring in fish products. During the production of powder, the raw fish material is heated to a temperature of 90 degrees. Water and oil is then removed by pressing to ensure effective drying. However, water soluble...

Tilapia, a fish that originates from southern countries, has been introduced in over 100 countries. It is the second most commonly produced fish in aquaculture in the world after carp (99 per cent is produced and consumed in China). Raising tilapia is easy and inexpensive. It adapts well to fresh or salt water and fattens fast. Unlike most salmoniforms in aquaculture (salmon, trout, perch, bream), for which fishmeal and fish oil constitute an essential part of their diet, tilapia is...

THAILAND - Researchers from the Medical Sciences Department have developed a test kit that can detect the presence of the deadly poison tetrodotoxin in puffer-fish meat within five minutes. The kit will be available for use early next year, said Deputy Public Health Minister Vallop Thaineua yesterday. The symptoms caused by tetrodotoxin, a neurotoxin found in puffer fish, typically develop within 20-30 minutes of consumption. The poison's effects start with...
