It takes guts to advance sustainability in aquaculture
With byproducts representing between 25 to 50 percent of the weight of various fish species, we need to be looking at how the entire fish is being used: even the heads, guts and skin.

With byproducts, getting more from – and for – fish
Use of fish trimmings and byproducts in fishmeal and fish oil is a win for aquaculture. But challenges loom, including logistics and economics.

GOAL video: Gorjan Nikolik on fishmeal
Gorjan Nikolik, senior industry analyst for Rabobank, presented on fishmeal’s transformation from commodity to a “high-priced strategic protein” at the Global Aquaculture Alliance’s annual GOAL conference in Vancouver. See the full video of his presentation.

Gamma irradiation enhances nutritional value of animal byproducts
Gamma irradiation treatment presents a possible processing technique for reducing anti-nutrients and improving the nutritive quality of many feed ingredients.

Animal protein meals reduce feed costs but don’t improve shrimp performance
The authors conducted a study to determine how replacement of salmon meal with various animal protein meals in feed affected the growth performance of white shrimp.

Fishery byproducts evaluated as feeding stimulants in plant-based shrimp diets
New cost-effective additives, such as fishery byproducts, will likely be needed to meet the increasing demand for feeding stimulants by aquafeed producers.

Protein isolates recovered from processing could yield nutraceutical seafood products
Meat recovered from seafood processing byproducts could be combined with nutraceutical ingredients to form customizable seafood items.

Single-cell proteins from food byproducts provide protein in aquafeed
Wastes produced during food processing can be treated to generate a valuable single-cell protein ingredient for aquafeed with protein and amino acid content similar to fishmeal.

Animal byproducts can provide cholesterol for shrimp feed
Animal byproducts like blood meal, meat and bone meal and other rendered products are good sources of cholesterol for use in aquaculture feed.

Fish silage: Bioconverted waste yields useful byproducts
Although its final quality can be variable, fish silage can be an effective protein supplement in feeds for various fish, shellfish and terrestrial animals.

Shrimp processing byproducts find many uses
Shrimp processing byproducts are constructively used in shrimp or fish feeds, livestock feeds and plant fertilizer. Chitin from shrimp exoskeletons is used in bandages and varied cosmetic products.

Pilot system recovers protein, lipids from fish byproducts
It is technologically feasible to recover functional muscle proteins and lipids from fish processing byproducts using isoelectric solubilization/precipitation.
Responsibility
Protein, lipid recovery from fish-processing byproducts
West Virginia University developed a lipid and protein recovery process from byproducts that reduces disposal concerns in the process of fish processing.

Rendered animal byproducts: A necessity in aquafeeds for the new millennium
Of all the sources of animal protein and energy available for aquafeeds, the largest is rendered animal byproducts.
