Evaluating plant protein sources replacing fishmeal in juvenile white shrimp diets
In this study, plant proteins – soybean meal, fermented soybean meal and sesame meal – were evaluated as fishmeal replacements for Pacific white shrimp.
Point: There are no essential ingredients in aquaculture feeds
Kevin Fitzsimmons, leader of the F3 (fish-free feed) Challenge, says aquaculture may currently depend on fishmeal and fish oil, but farmed fish do not.
Testing diets without fishmeal and fish oil for kampachi
An evaluation of experimental juvenile kampachi (Seriola rivoliana) diets – with zero fishmeal or fish oil – finds significant potential.
Will krill fulfill its promise as an aquaculture feed ingredient?
Krill has been shown to augment aquafeeds but utilizing and protecting the resource demands specialized equipment and a patient, collaborative approach.

In vitro protein digestibility of a microbial-enhanced protein for juvenile white shrimp
A microbial-enhanced protein for juvenile Pacific white shrimp showed higher levels of hydrolysable protein and better digestibility than soybean meal.
Evaluating extruded feeds for juvenile Pacific white shrimp
In a study of extruded feeds given to Pacific white shrimp juveniles, results showed shorter crop cycles, higher production yields and a cost reduction.
Is a ‘baby food’ bottleneck looming for aquaculture?
Global aquaculture, particularly farmed shrimp, depends on artemia for hatchery feeds. Supplies meet current needs, but growth will require alternatives.
