Optimization of the autolysis of rainbow trout viscera for amino acid release using response surface methodology

Optimization of the autolysis of rainbow trout viscera for amino acid release using response surface methodology

Aquaculture has grown exponentially during the last decades, even overcoming traditional fishing in volume since 2012 (Iñarra et al, 2018). The rise of the production of fish involves the rise of fish by-products, that in case of being disposed could suppose an environmental risk. Fish viscera are part of the by-products used to produce fishmeal and are the 10-18% of the whole fish weight.

sLCA methodology and standards applied to bio-based fertilizers from fisheries/aquaculture wastes

Fish and aquaculture production has constantly grown following demographic evolution. According to the FAO (FAO, 2022), the production of these sectors should reach 202 million tons in 2030, with aquaculture increasing its proportion to about half. Even if food/fish loss is not taken into account, a large quantity and diversity of wastes is generated such as fish sludges, bones, viscera and heads, mollusc shells …
