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...
Capture-based aquaculture will give Norwegian seafood a competitive advantage. However, uncertainty about profitability means that few fishermen go in for live fish, a Fiskeriforskning study shows. The Norwegian fishing industry can gain a competitive advantage by landing more live fish. There is an increasing demand for fresh fish. However, large seasonal fluctuations in the fisheries mean there are long periods with insufficient supply of fresh fish products....
A Prince Edward Island (Canada) mussel processor has recently been granted a patent that will allow him to package his product in a ground breaking way. Modified Atmosphere Packaging (MAP) is a watertight process that uses a special oxygen/carbon dioxide mix to keep mussels alive for much longer than regular packaging and in a consumer friendly, airtight package. “I am extremely excited about the opportunities this new technology holds for the shellfish industry in...
Scientists have managed to breed trout from salmon using a new technique they hope will allow them to create tuna fish from mackerel. The Japanese researchers hope to produce stocks of valuable, endangered species by injecting their germ cells into sterilised embryos from other species. Goro Yoshizaki, a marine biologist, from the Tokyo University of Marine Science and Technology, Japan, used the method to successfully breed trout from salmon. The embryos they produced...
National Prawn Co. (NPC), the world's largest fully integrated desert coastal aquaculture project, is set to debut at Sea Food Expo 2007, the Middle East's first exhibition dedicated to the seafood industry, which will be held from October 29-31, 2007, at the Crowne Plaza Hotel, Dubai. The fully-integrated hatchery, farm and processing facility located south of Jeddah, KSA, was built at a cost of more than $350m, and was established in a bid to tap into the booming global seafood market,...
To protect fish farms and hatcheries from outbreaks of water-borne diseases, water treatment specialist Hanovia Limited has developed a high intensity UV disinfection system. Capable of treating up to 700m3/hr of both fresh or sea water with at least a 99.99% kill rate, the UV system can be used to treat both incoming and recirculation water, allowing flexibility in the choice of site and a rapid payback for farmers. Increased water extraction and lowered water quality can result...
A farmer whose sole product is fish can harvest bigger profits if a vegetable or herb crop is added to the system, said presenters at a conference on aquaculture. This form of agriculture, called aquaponics, is still rare in Alberta, said Nick Savidov, a research scientist with Alberta Agriculture's crop diversification centre in Brooks. Bacteria convert the fish waste to nutrients, which are taken up by plants growing in hydroponic troughs. The plants clean the water, which is...
Recent trials have shown that the salmon harvesting plants can commence using a machine that slaughters salmon quickly and humanely. The current method in use, CO2, will be banned from 1 July next year. Industry-scale trials have been carried out at one of Marine Harvest's salmon farming plants in Rogaland. The salmon are pumped up directly from the pens to a vessel that had been especially outfitted for the trials. Trials were also carried out using a system...
