The efficacy of a single cell protein (SCP) methanotroph (Methylococcus capsulatus, Bath) bacteria meal (FeedKind®, Calysta, Menlo Park, CA, United States), in Pacific white shrimp (Penaeus vannamei) diets was studied to determine growth performance, survival rate and disease resistance against Vibrio parahaemolyticus causing Acute Hepatopancreatic Necrosis Disease (AHPND). The growth trial wa ...

Paul Roberts Most commercial plant protein ingredients are highly digestible to animals. The insoluble carbohydrate found cell walls have no negative real impacts, except at extremely high levels.

Eric De Muylder This paper is a couple years old since 2017. I totally agree 4.5 gram shrimp is 2 months old for vannamei. Indeed feed formulation is bad, using 38% of soybean and the rest of plants protein. Anyway the result is so poor.

You start from a really bad formulated control feed. You do everything possible to have low growth, like removing faeces, molts, and starving the shrimp every day for 16 hours.
You achieve 150 % growth in 150 days ? Starting from 4,5 gram, it means your shrimp were 11 gram 5 months later ? I really don't see the point of publishing such results. It is so far away from any results in the shrimp fa ...

Seaweed cultivation is well established in Asia and needs little explanation/justification. In the western world, a renewed interest in seaweed mariculture has been triggered by their cultivation in integrated multi-trophic aquaculture (IMTA) systems, the emerging understanding of the ecosystem services they provide (e.g. nutrient biomitigation, irrigation-less and deforestation-less food pr ...

The best environments are those ones that are in fact natural homes for the species being farmed. There is no identical artificial ecological factory that will mimic this scenario. One must think about generating that ecological home by putting less production pressure on that environment used for farming.
