Toward environmentally sustainable aquafeeds: Managing phosphorus discharge from Nile tilapia (Oreochromis niloticus) aquaculture with microalgae-supplemented diets

Elementa: Science of the Anthropocene (2021) 9 (1): 00170.

Phosphorus digestibility results suggest that Schizochytrium sp. is a good candidate for developing tilapia feeds that minimize phosphorus loading. Partial or complete substitution of conventional ingredients with certain microalgae species could result in a feed with greater phosphorus digestibility, reducing the phosphorus load in the aquatic environment into which the aquaculture waste is discharged.

Evaluation of fish oil content and cottonseed meal with ultralow gossypol content on the functional properties of an extruded shrimp feed

Aquaculture Reports, Volume 19,2021

This study analyzed the extrusion processing potential of glandless cottonseed meal (GCSM) in extruded shrimp feed. Five different diets with different fish oil concentration and constant GCSM content were extruded. Extrusion temperature, screw speed, and moisture content were varied. Overall results demonstrated that using GCSM as a fishmeal substitute in extruded shrimp feed might be a feasible alternative to reduce feeding costs while showing high protein, minerals, essential fatty acids, and amino acids content.

Disintegration stability of extruded fish feed affects gastric functions in Atlantic salmon (Salmo salar)

Aquaculture, Volume 543,2021

Two salmon feeds with different disintegration stabilities were produced by impacting extruder viscous heat dissipation with the use of different lipid levels in the feed mix. The feeds were then dried and coated to similar final lipid levels (30-31%) and nutritional composition. Both feeds were produced as 4 and 6-mm pellets. Feeds extruded with 20% lipid had a lower disintegration stability compared with those with 8% lipid. The feeds were used in two feeding studies using Atlantic salmon and an in vitro gastric study.
