Abstract
Abstract Five isolipidic experimental diets (32% crude protein) were formulated to contain 3% fish oil (FO) and virgin coconut oil (3VCO) as sole lipids or blends of FO + VCO in ratios of 75:25% (0.75VCO), 50:50% (1.5VCO) and 25:75% (2.25VCO). Triplicate groups of O. niloticus were fed one of five diets to apparent satiation, twice daily for 8 weeks. It was observed that fish fed diet 3VCO exhibited the best performance with respect to feed intake (492.1 g), final weight (214.60 g) and weight gain (154.90 g). Significant effects of dietary fatty acid profile were reflected in fish fed the diets in whole body, muscle and liver C12:0 and C14:0. However, eicosapentaenoic (EPA, 20:5n-3) and docosahexaenoic (DHA, 22:6n-3) were significantly different ( P  ≥ 0.05) compared to their respective diets while liver n-3: n-6 ratio significantly increased and recorded low levels in whole body and muscle. Statistically, least values of mortality were recorded as VCO levels were elevated when fish were subjected to Streptococcus iniae infection while plasma metabolite indicators among treatments were not altered. The inclusion of VCO at 3% in the diet gave excellent performance, indicating that it could wholly replace FO and as such represents a better alternative lipid source for feeding O. niloticus .

The present study was conducted to evaluate the effects of extruded diets and pelleted diets with varying protein levels on growth performance and nutrient utilization of tilapia. Six diets, containing three levels of crude protein (CP) of 250, 280 and 310 g kg−1, were prepared by pelleting (sinking) or extruding (floating) and were fed to tilapia juveniles (body weight of 8.0 ± 0.1 g). After 8-week feeding, the weight gain (WG) and feed conversion ratio (FCR) of the six groups (pelleted diets w...

Abstract The use of alternative lipids in tilapia feeds is becoming increasingly commonplace due to the rising cost of fish oil (FO). However, since this practice will reduce the content of heath beneficial long chain polyunsaturated fatty acids (LC-PUFA) in tilapia fillets, investigations on finishing diets to enhance their nutritional value prior to harvest are increasing. A five month grow-out trial was conducted to evaluate the replacement of dietary FO with FO + crude palm oil (CPO) (1:1), ...

A 60-day feeding trial was conducted to determine the effects of palm oil blended with oxidized and non-oxidized fish oil on growth performances, hematology, and non-specific immune response in juvenile Japanese sea bass, Lateolabrax japonicas. Japanese sea bass (1.73 ± 0.01 g) were fed seven experimental diets containing 100 g/kg of dietary lipid in forms of palm oil (10P), fish oil (10F), fish oil blended with palm oil at different ratios, 6:4 (6F4P) and 4:6 (4F6P), oxidized fish oil (10OF), a...

Six practical extruded diets were formulated to investigate the effect of graded levels of starch (17, 22, and 26%) associated with either 30 or 34% protein level on growth, feed utilization, body composition, and hepatic transaminases of juvenile grass carp, Ctenopharyngodon idella. Over an 8-wk growth trial, survival rates (99–100%) were not significantly affected (P > 0.05) by dietary treatments. Independent of dietary starch level, weight gain (WG, %), specific growth rate (SGR, %/d), and fe...

Abstract A 9-week growth trial was conducted to investigate the effects of dietary cholesterol supplementation on growth performance, feed intake and cholesterol metabolism of juvenile turbot ( Scophthalmus maximus L.) fed high plant protein diets. A fish meal diet (diet FM) with 58% FM was formulated, and this diet was used as control. The other four diets were formulated to contain 14.5% FM, 42.0% soybean meal (SBM), and 18.5% wheat gluten meal. The four diets were supplemented with 0.0%, 0.5%...

Abstract Fish oil (FO) sparing is common in aquafeed formulation; however, some alternative lipids have proven to be more successful than others in ensuring adequate growth and maintenance of desirable fillet fatty acid (FA) composition. Depending on the lipids used, grow-out feeds influence the FA composition of the tissues of “lean-fleshed” fishes and their responsiveness to subsequent tailoring during finishing. To address whether different lipid sources similarly influence growth performance...

Abstract Tilapias have been shown to have a dietary requirement for linoleic (n-6) series fatty acids (FAs; 18:2[n-6] or 20:4[n-6]). The optimum dietary levels of n-6 previously reported were 0.5% for redbelly tilapia Tilapia zillii and 1.0% for Nile tilapia Oreochromis niloticus. Tilapias may also have a requirement for the linolenic (n-3) FA series (18:3[n-3], 20:5[n-3], or 22:6[n-3]), but the optimum dietary requirement levels for n-3 in various tilapia species have not been determined. The p...

Global shortages in fish oil are forcing the aquaculture feed industry to use alternative oil sources, the use of which negatively affects the final fatty acid makeup of cultured fish. Thus, the modulation of fatty acid metabolism in cultured fish is the core of an intensive global research effort. The present study aimed to evaluate the effects of various dietary α-linolenic acid (ALA, 18:3n-3)/linoleic acid (LA, 18:2n-6) ratios in cultured fish. A feeding trial was implemented on the freshwate...

Abstract A 2 × 2 factorial 14-week feeding trial was conducted to evaluate the fatty acid metabolism in two different tilapia genotypes [Nile tilapia ( Oreochromis niloticus , GIFT strain) and red hybrid tilapia ( Oreochromis sp .)] fed a fish oil (FO)- or blended vegetable oil (BVO)-based semipurified diet. The BVO was formulated using olive oil (15%), sunflower oil (15%), linseed oil (30%) and refined, bleached, deodorized palm olein (40%) to mimic the major fatty acid classes of FO. In genera...

A 12-week feeding trial was designed to evaluate the effect of total replacement of fish oil (FO) with terrestrial alternative oils on growth, feed utilization, body composition, hematological parameters, and fillet fatty acid profile of mandarin fish juveniles. Four iso-nitrogenous (56% crude protein) and iso-lipidic (13% crude lipid) practical diets were formulated. A control diet contained 6% FO and three other experimental diets were prepared by replacing FO with linseed oil, soybean oil, an...

Abstract This study aimed to evaluate the influence of dietary pure linseed oil or sesame oil or a mixture on innate immune competence and eicosanoid metabolism in common carp (Cyprinus carpio). Carp of 100.4 ± 4.7 g were fed to satiation twice daily for 6 weeks with four diets prepared from three lipid sources (CLO; LO; SO; SLO). On day 42, plasma was sampled for immune parameter analyses, and kidney and liver tissues were dissected for gene expression analysis. On day 45, HKL and PBMCs from re...
