In the second part of our interview with the associate head of research at the School of Life and Environmental Sciences at Deakin University (Australia) he discusses the various alternative sources of omega-3 fatty acids coming on to the market and why research is crucial to advancing aquaculture. 

India has a small trout farming industry in the Himalayan and Southern Peninsula areas. Even though current annual production is only a few hundred tons, the country has many areas that, although geographically difficult to work in, also offer excellent, very large habitats and conditions for trout culture. 

At the biannual International Symposium on Fish Nutrition and Feeding in Idaho, experts from around the world will discuss fish nutrition and health, feed research, cellular nutrition, nutritional modeling, nutrigenomics and effective feeds for quality consumer products. 

La acuacultura de camarón marino y tilapia en Brasil se inició con una orientación a la exportación de sus productos. En 2003, más del 60 por ciento del camarón cultivado fue vendido en el extranjero. La industria de la tilapia soñaba sobre la exportación de filetes frescos a los Estados Unidos y Europa, y logro exportar algo.

One should expect high value fish products like shrimp, tilapia, Chilean salmon and cod being replaced by more affordable seafood and alternative meats, as consumers keep losing purchasing power due to inflation, unemployment and monetary devaluation. 

Facing shifting pricing and availability for traditional aquafeed ingredients, formulators are increasingly moving toward alternative starch and protein from plant sources like pea products. 

Key molecules found in animal byproduct hydrolysates show potential for use as functional ingredients in aquaculture feeds. Animal co-product hydrolysates from slaughterhouse waste and rendered animal byproducts present a protein alternative. 

Mycotoxins are naturally occurring, toxic chemical compounds produced by molds. When they infect aquaculture feeds and feed ingredients, mycotoxins can affect growth, reproduction and immunity in fish. 

Aquafeed manufacturers can ensure quality by looking beyond price and with written ingredient specifications adhering to nutritional formulations. 

BMPs for salmon feed manufacturers cover formulation and evaluation of ingredients, while farmers should focus on amount, frequency and delivery of feed.
