Adoption of the ecosystem approach to fisheries management relies on recognition of the link between fish and other components of the ecosystem, namely their physical and biological habitat. However, identifying the habitat requirements of marine fishes and he…
Chinas output of aquatic products in 2011 amounted to 56.1 million tons, a YoY rise of 4.4 per cent; at the same time, the disparity between seawater and freshwater products in production ratio was narrowing year by year, accounting for 51.9 per cent and 48.1 …
ETH researchers have for the first time succeeded in discovering the optimal escape response of fish using a supercomputer. The aim was to test whether the escape mechanism of small fish, developed in the course of evolution, is optimal for achieving the maxim…
Evaluations of the passage of feed through the intestines of white shrimp shows that shrimp consume feed much faster when temperatures are above 32 C, writes Dr Carlos A. Ching, Kasetsart University, Thailand. Taken from the Global Aquaculture Advocate, a Glob…
Fishers and fish-farmers should, given the dependence of their businesses and livelihoods on ecosystem services, be stewards of the marine environment, according to the Green Economy report by the United Nations Environment Programme (UNEP).
Scientists at Liverpool University are developing a new plant-based product that could replace fishmeal, reducing the need for farmers to feed fish to other fish at a time when more than 90 per cent of EU waters are at risk from overfishing.
Speaking at the World Fisheries Congress 2012, Graham Patchell, from the Sealord Group New Zealand and Chief Scientist for the Southern Indian Ocean Deepsea Fishers Association (SIODFA), asked whether deepwater fisheries were overfished or simply misunderstood…
Low-input culture practices have been developed for freshwater prawns to effectively manage their growth and biological characteristics. With low nutritional requirements for long-chain fatty acids, the prawns can be grown on diets with no fishmeal or fish oil…
More research in recent years has provided significant insight into how the sun affects temperature and quality of dried fish. This shows that shadow network has no impact on the quality of the fish.
Despite Atlantic cod and haddock extending further into Arctic waters, a new study reveals there is little competition for food between the invaders and native polar cod. However, it is uncertain whether climate change will increase competition between the spe…
This study aims to investigate the impact of commonly used pesticides (deltamethrin) on the blood and tissue oxidative stress level in catfish; in addition to the protective effect of alpha-tocopherol on deltamethrin induced oxidative stress, write Kamal A Ami…
Shrimp supply squeeze from bad weather and production problems keep prices high but new season will bring relief. No crisis for imported shellfish and canned molluscs in European markets, according to the FAO Global Food Outloook.
Researchers have demonstrated that hatching in polar cod can begin as early as January in Arctic seas that receive large freshwater input, compared to April-July in seas with little freshwater input. Since early hatching leads to higher survival rates, the eff…
Good quality and improved quality control are important for salmon producers. Effective measurement methods that investigate how light scatters through the flesh of the fish can be of great help.
The worlds fisheries and aquaculture sectors have gone through a dramatic development in the last 60 years, and there have been large increases in their production, according to the Food and Agricultural Organisation of the UN.
Asian carp, that large, invasive fish known for leaping out of a river into boats when startled, now make up more than 60 percent of the total fish biomass in one of Illinois' major river systems, a research team led by Southern Illinois University Carbondale …
This overview report addresses opportunities for the development of the Pacific Islands mariculture sector in general terms. More specific analysis of opportunity in particular countries is presented in the five accompanying country reports for the Cook Island…
Doctoral research carried out by Mona Gjessing from the Norwegian School of Veterinary Science shows that pathological changes in cod differ from those found in diseased salmon, and cod that appear clinically healthy can nevertheless be affected by extensive c…
While Nile perch popularity in the German market was enhanced by Naturland certification, the US will probably face strong competition from Australian barramundi.
Marine fisheries are very important to the economy and well-being of coastal communities, providing food security, job opportunities, income and livelihoods as well as traditional cultural identity. This FAO publication, Review of the State of World Marine Fis…
Of the 50 species fished in the Baltic sea, the majority are overfished. This report, Sustainable Fisheries Management in the Baltic Sea, from Ocean looks at the biggest problems affecting Baltic Sea fisheries and recommends the application of an ecosystem bas…
Good fishing in South America and improved access to raw material has pushed fishmeal production higher over the last months with total production for 2011 about 40 per cent above 2010 levels in the major producing countries. The increased supply eliminated an…
Every day, new reports are published in newspapers worldwide reporting about the effects of antibiotic resistant bacteria and their consequences on human health, according to Biomin.
Roughly one-third of the edible parts of food produced for human consumption, gets lost or wasted globally, which is about 1.3 billion ton per year. Food is wasted throughout the food supply chain, from initial agricultural production down to final household c…
Hybrid catfish offer productionadvantages over channel catfish.Trials have shown the greatersurvival and faster growth of thehybrids allows shorter productioncycles. The hybrids alsohave better feed conversion andfillet yield, writes Nagaraj G. Chatakondi, USD…
During 2011, most producers scaled back production from the previous year, leading to higher prices, in particular for bream. The situation soon after returned to normal with bass quoted higher than bream, which is the usual price.
