Growth and body composition of channel catfish (Ictalurus punctatus) fed diets containing various percentages of canola meal | Semantic Scholar (2024)

It may be concluded that 20% fishmeal protein can be successfully replaced with canola meal, while supplementation of amino acids or blending with complementary proteins could facilitate higher fishmeal replacements in kuruma shrimp diets.

It is suggested that up to 40% of fish meal protein can be replaced with CGM in the diet of juvenile Japanese flounder, and supplies of crystalline amino acids to the CGM diet improved the nutritive value of the diet.

Higher dietary fish meal replacement negatively affected diet quality and palatability resulting in reduced feed intake, feed efficiencies and fish performance, but blood serum values of triglycerides, glucose and protein were not significantly different between treatment groups, still indicating a favourable nutrient supply from all experimental diets.

Canola meal has potential to replace substantial levels of fish meal in diets for carnivorous fish without compromising performance and the liver fatty acid composition reflected that of the diet with a higher level of polyunsaturated (n-6) fatty acids in fish fed diet canola meal.

The tested CPI was identified to be a highly valuable fish meal alternative, not negatively affecting diet palatability, feed intake and feed efficiencies.

Use in higher level of canola meal in tilapia diet was adversely affected growth parameters and FCR, which resulted in lower protein digestibility and cellulose digestibility.

Protein from canola meal can replace up to 10% of protein from fishmeal in diets for tilapia fry, and weight gains declined beyond this replacement level, probably because of increased levels of antinutritional factors, particularly glucosinolates.

Dose-related changes in the histological appearance of the thyroid and alterations of plasma thyroxine and 3,5,3′-triiodothyronine levels indicated that compensatory adjustments in thyroid function allowed normal growth to proceed in the canola-fed fish.

Cottonseed meal can be used to partially substitute for soybean meal in catfish feeds and free gossypol levels were below detectable limits in fish tissue, suggesting that cottonseed meal should be limited to 15% of the catfish diet.

It is suggested that a diet with an all-plant protein source (SBM) can totally replace fish meal in a diet for blue catfish, without adverse affects on weight gain or body composition, when the dietary protein level is 35% and fish are fed to satiation.

Two studies were conducted to evaluate cottonseed meal (CSM) with and without supplemental lysine as a substitute for soybean meal (SBM) in catfish feeds, demonstrating that channel catfish can effectively utiliz...

Canola meal supplementation to the trout diet affected the thyroid gland of the fish, producing a diffuse, microfollicular hyperplasia that increased in severity with increasing CM supplementation.
