Impact of three different types of seaweed diets on growth, feed utilization and nutrient digestibility of L. rohita was studied for 120 days. The seaweed diet fed fishes, especially Ulva based diet showed comparatively higher growth and weight increment. Good food conversion ratio, food assimilation efficiency, protein efficiency ratio and better nutrient digestibility were recorded for seawee...

Dietary availability and retention of selected minerals associated with the intensive production of rainbow trout (Oncorhynchus mykiss). Donna Leanne Snellgrove This research programme aimed to review the nutritional requirements for the main minerals, (namely calcium, phosphorus, magnesium and zinc) formulated in commercial diets that are essential for the health and growth performance for sal...

Aquaculture struggles with sustainability due to the use of fishmeal, and insects are one potential alternative. Insects have low long-chain omega−3 polyunsaturated fatty acid content, insect-fed fish reflect this in their composition. In total, 500 rainbow trout (Oncorhynchus mykiss, ~46 g) were fed until reached a commercial size (~415 g). Five diets used: control based on fishmeal as main so...

Abstract A six-treatment study in a 3 × 2 factorial design was conducted to investigate whether dietary supplementation of shrimp hydrolysate (SH) improves the efficacy meat and bone meal (MBM) replacing fishmeal protein juvenile giant trevally Caranx ignobilis . fishmeal-based diet (MBM0) used as control; two low diets were prepared by 25% (MBM25) 50% (MBM50) with MBM; another three treatments...

There is a growing concern about the use of fisheries-derived proteins in aquaculture. This study was conducted to investigate effect either partially or totally replacing fishmeal (up 15% diet) by inactivated dry yeast product DY-Pro Nile tilapia Oreochromis niloticus diets. The replaced 0% (DY-PRO0), 2% (DY-PRO2), 5% (DY-PRO5), 25% (DY-PRO25), 50% (DY-PRO50), 75% (DY-PRO75) 100% (DY-PRO100) p...
