A new Glitnir Seafood Industry Report shows that the global catch of tuna has stagnated and the stocks of the most popular subspecies are currently either fully exploited or even in a stage of depletion. The future of the tuna industry depends largely on the development of successful aquaculture. Glitnir, the globally leading supplier of financial services to the seafood industry, releases its new report on the tuna industry today. The report provides an analytical overview of the...

Bluefin tuna use three times as much oxygen as other fish their size, making them more difficult to culture, according to new research at the University of Adelaide. The findings have been made by Earth & Environmental Sciences PhD student Quinn Fitzgibbon and colleagues, in a study where they monitored live tuna swimming inside a 350-tonne "waterbed". The research team also found that tuna use twice as much energy processing their food as any other fish, and so need to eat...

The implications of breeding between farmed and wild salmon will be investigated in a new project led by scientists at the University of East Anglia. For the first time researchers will measure the fertilisation compatibility between farmed and wild salmon, and therefore the risk of farmed genes entering wild populations, which are in severe decline. Wild Atlantic salmon stocks have fallen by more than 50pc, mainly through poorly-managed fisheries and deterioration of feeding and...

So what does an underwater cage full of white sea bass miles out in the ocean have to do with a sugar beet farm in northern Utah? Everything, as far as Donald Kent is concerned. It was a sugar beet farm that sustained Kent's father, Sidney Kent, and his family during the Great Depression. And though the elder Kent eventually left the farm and moved to San Diego to become a physical therapist, the farm never really left him. “He loved working the land and taught us about food...

The ever-growing population and shift in food habits have resulted in increased demand for fish and related products. Increasing awareness about health benefits offered by fish and aquatic plants against red meat is also a major demand growth driver. The global market for aquaculture and fisheries is projected to maintain a CAGR of about 3% over the ten-year analysis period and exceed 123 million tons by 2009. About 1.0 billion human beings worldwide depend on fish as their primary...

China will step up inspections on the use of antibiotics in fish farms, including chemicals that can cause cancer, after contaminants caused trading partners to block its seafood exports. "We are focusing on getting a hold on antibiotic use, especially overuse of antibiotics on fish and crustaceans, including nitrofurans and malachite green," Zhang Yuxiang, director of the market and economic information department of the Ministry of Agriculture, told a news conference on...

This research on the quality of farmed Southern Bluefin Tuna (SBT) (Thunnus maccoyii) has been focused on improving the colour shelf life of the sashimi product. Previous outcomes of our research group and supporting data from associated project groups have led to the current interest in evaluating the use of a supplementary feed for tuna farming that can be used to extend shelf life. As with terrestrial red meats, shelf life is an important product quality feature of farmed SBT....

The sight of fish swimming in old sewage tanks might be disconcerting to some. But one researcher hopes the paddlefish growing at Frankfort's wastewater treatment plant might one day lead to another source of food for consumers and income for limited resource farmers. It's all a part of a combined effort from public and private entities "including Kentucky State University" to research a groundbreaking form of aquaculture using old and unused resources at the plant to grow...

In a happy marriage between gastronomy and sustainable development, two savvy Dutchmen have devised a way to tap waste heat from a power plant to raise tropical shrimp for the food market. The year-old business is nestled next to a dune at the foot of the huge Eon power plant on the otherwise uninspiring industrial park at Rotterdam's port, known as the Maasvlakte. With only imposing factories and chemical plants, it seems an unlikely site for a place called the Happy Shrimp Farm....

Local researchers have discovered a new way to farm shrimp in record-breaking numbers. At the Oceanic Institute in Waimanalo Friday -- they demonstrated how the system works. The shrimp are grown in a small holding tank for about 14 weeks. Unlike traditional shrimp farming, researchers say, this method is environmentally friendly. It produces a large amount of shrimp using less water, electricity and space, and it's cost effective. "That's really exciting to...

Publication of the human genome draft sequence (Lander et al., 2001; Venter et al., 2001), and those of other species represent major milestones in scientific discovery. This genomic unraveling has helped identify the functions of numerous unknown genes and, in certain cases, has assisted in determining the roles of specific genes in disease processes. The genomic revolution incorporates much more than the decoding of organismal genomes alone, however. Critical to the success of this field...

Fiskeriforskning has detected a substance in fishmeal that can mean many hundreds of millions of Kroner (NOK) in increased revenues for the Norwegian aquaculture industry. The fish feed must contain about 30 % fishmeal in order for the salmon to grow and develop normally. But because fishmeal is a scarce resource and an expensive ingredient in the salmon feed, the producers have been using increasingly larger amounts of vegetable ingredients from agriculture....

South African aquaculture production, though limited in its contribution to Africa's and global production, has shown a significant increase over the past few years. Total production and value has increased from 3000 tons (R51 million) in 1997, to 4624 tons (R136 million) in 2003 - a 54 percent increase in weight and 167 percent in value (Hoffman, et.al., 2000; Brink, 2003 personal communication). A potential aquafeed market of 3071 tons can be projected from these values when...

Cultivated mullet fish were compared with the wild mullet fish from four locations during summer and winter 2005/2006. This work was evaluated via chemical analysis of feed, water, sediments and fish besides their contents of three heavy metals (Cd, Fe & Pb) and three pathogenic microbial genera (Salmonella, Shigella & E. colli). From the foregoing results, it could be concluded that there is pollution with heavy metals (particularly with iron and lead) and pathogenic bacteria (especially E....

One would not adequately do justice to the above topic until the key words are defined. Therefore, the best way of tackling such assignment is to collectively, where applicable join, and where necessary, separate the words and their definitions. Prospects, to start with, are the possibilities or likelihoods of something happening, while livestock refers to animals such as cows and sheep; and bird such as chickens kept on a farm. Processing...

The latest review of the state of world aquaculture from the Fisheries and Agriculture Organization (FAO) 2003 and the latest FAO Fishstat Plus statistics from 1950-2001 highlight the continuing growth of aquaculture in contributing to the total fisheries catch (Figure 1). Aquaculture represented 5.3% of the total fisheries landings in 1970 and this had increased to 34% in 2001, i.e. 48.4 million metric tonnes (mmt) of the total fisheries landings of 142.1 mmt. The value of world...

Asia has a long history of aquaculture activity consisting of simple, low-cost, extensive culture methods, mainly for household and local consumption. However, in the past two decades, technical advances in culture methods and systems, and increasing market demand in the light of stagnating wild catches, have resulted in significant increases in production levels and efficiencies, especially in export-oriented sectors of the industry such as shrimp. According to the Food and...
