Just like people, fish need their daily quota of vitamins. For instance, one of America's most popular farmed fish, rainbow trout, need at least a dozen different kinds of vitamins so they can grow normally and stay healthy.
Now, ARS fish nutritionist Rick Barrows has made it easier for trout and other fish to get those vitamins. He's done that by developing an updated, preblended vitamin mix. It's a publicly available recipe-technically known as a "formula." And, it's...

Lateral line sensory system detects vibrations from unseen prey
Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its lateral line sensory system to detect minute vibrations made by prey hidden in the sediments.
The lateral line system is composed of a canal embedded in the scales along the side of the body...

Fish feed wastage and its impact on water-bodies are a major source of worry for the fisheries industry. The accumulation of waste leads to toxicity in farmed species.
High quality protein is essential for shrimps to grow fast. They require 45 percent quality protein in the supplementary feed. This makes shrimp feed costly and accounts for more than 55 percent of the operational cost.
Researchers at the School of Industrial Fisheries, Cusat, led by director Madhusoodana Kurup...

Hard-pressed farmers in developing countries could be thrown an economic lifeline after a lucky discovery by French scientists involving a useless palm oil by-product and the lowly maggot.
The synergy of two otherwise nuisance agents produced a virtually cost-free feed for farmed fish while reducing a pungent source of pollution -- a potential boon in countries like Indonesia, one of the world's largest palm oil producers.
"This process will allow us to recycle palm oil...

In a feeding trial, farmed Atlantic salmon were given feed with a high content of plant protein. Only 15% of the protein was marine protein. The results from the National Institute of Nutrition and Seafood Research (NIFES) show that less protein is deposited in the salmon when it is given feed containing high levels of plant protein.
Atlantic salmon in salt water weighing around 640 grams were given either a feed containing mainly fish meal as protein source or a...

Micro-algae are growing faster under the influence of climate change. However, the composition of the algae is changing, as a result of which their nutritional value for other aquatic life is decreasing. And because algae are at the bottom of the food chain, climate change is exerting an effect on underwater life. This is the conclusion of researchers from the Netherlands Institute for Ecology (NIOO-KNAW) and the Universiteit van Amsterdam.
Dutch researchers wanted...

Statistics used by Greenpeace against the fishmeal industry are outdated.
Sir, You report the UN Food and Agriculture Organisation (FAO) recommendation that there should be a big increase in fish farming to meet the rising global demand for seafood, and the assertions by Willie Mackenzie, of Greenpeace, that "it just doesn't make sense to catch fish to feed to fish - you use four to five times the weight".
Mr Mackenzie's figures are out of...

With the spawning season over for the year, it's a good time to evaluate baitfish fry survival and growth. Hopefully it's been a good year and you have ponds full of new fish. If not, you may want to consider some pond management changes.
What's a normal survival rate? In a study conducted in UAPB research ponds, survival from matted egg to juvenile size (called "peewee", weighing 0.5-2 lb/1000 fish) ranged from 9 percent to 47 percent and averaged 24 percent. The losses took place...
