Abstract.— The current experiment was performed to determine apparent protein and energy digestibility coefficients of feed ingredients by the fecal stripping technique using extruded diets. tested included five fish meals, three terrestrial animal by‐products, plant concentrates, four seven low‐protein ingredients. Protein differed among meals ranged from 90% for fair average quality menhaden meal 97% anchovy meal. (ADCs) in concentrates a low 89% rice concentrate high 100% wheat gluten...
Abstract— A pair of experiments were performed to assess amino acid supplementation pet food grade poultry by-product meal for utilization as the sole protein source hybrid striped bass Morone chrysops×M. saxatilis. The first experiment determined available acids from menhaden fishmeal and bass. second efficacy supplementing with based on an ideal profile muscle. positive control diet contained 40% digestible solely negative meal. was additively supplemented lysine, methionine, threonine,...
Abstract Limited information is available on digestibility of nutrients in various practical ingredients used diets for commercially important finfish species, such as hybrid striped bass. This especially needed sunshine bass, Morone chrysops × M. saxatilis , to improve least‐cost diet formulations and allow effective substitution feedstuffs. A study was conducted with large (867 g) bass determine the apparent coefficients (ADCs) moisture, protein, lipid, organic matter (OM) a variety...
Two primary ways to achieve low-cost, nutritionally efficacious diets for sunshine bass (Morone chrysops × M. saxatilis) are decrease crude protein (CP) levels and the use alternative animal or plant ingredients partially, totally, replace fish meal. A 459-day feeding trial was conducted with juvenile (35 g) evaluate growth, feed efficiency, size distribution at harvest, immune function status body composition when fed containing soybean meal (SBM), feed-grade poultry by-product (PBM),...
A feeding trial was conducted in a closed system with Nile tilapia, Oreochromis niloticus, juveniles (mean initial weight, 2.66 g) to examine total replacement of menhaden fish meal (FM) distiller's dried grains solubles (DDGS), which had been used as substrate for the production black soldier fly larvae, Hermetia illucens, combination soybean (SBM) and poultry by-product (PBM), or without supplementation amino acids (AA) DL-methionine (Met), L-lysine (Lys) commercial non-amylaceous...
ABSTRACT Objective The objective of these two studies was to quantify the comparative performances yearling and 2-year-old reciprocal cross hybrid Striped Bass (White Morone chrysops ♀ × M. saxatilis ♂), also called sunshine bass, water quality in traditional split ponds an outdoor mixotrophic biofloc technology production system. Methods In study 1, two-year-old fish (247.9 g/fish) were stocked at 7,410 fish/ha (0.86 fish/m3) 6.3 fish/m2 (7.1 system tanks grown for 151–153 d. 2, (147.0...
The refinement of hybrid striped bass feed formulations has been progressing rapidly. There is still, however, limited information available regarding nutrient digestibility and amino acid availability from common feedstuffs. A pair experiments was conducted to determine the protein sunshine an assortment commercially animal feedstuffs, blended products plant feedstuffs in extruded diets. tested were blood meal, poultry by-product fish solubles, Pro-Pak 60, 65, ProCon 65RDB, 60FMC for...
Abstract The digestibility of nutrients and energy in various ingredients to fish is affected by a variety factors including ingredient quality processing. Limited information available regarding the feedstuffs for sunshine bass Morone chrysops ♀× M. saxatilis ♂. This particularly needed improve accuracy diet formulations allow appropriate substitution feedstuffs. Therefore, study was conducted with advanced fingerlings (50–75 g) determine apparent coefficients (ADCs) protein, lipid,...
The influence of carbohydrate level and complexity on in vitro hepatic glucose utilization lipogenesis were determined hybrid striped bass, Morone chrysops ♀ × saxatilis ♂. Six isocaloric, isonitrogenous diets containing glucose, maltose, or dextrin at two different levels (200 400 g kg−1 diet) fed to adult fish for 15 weeks. Liver explants obtained near-maximum postprandial glycaemic response incubated with radioactive labelled substrates. Glycogen synthesis from [14C]glucose was not among...
Requirements for six of the 10 indispensable amino acids (IAA) have not been quantified hybrid striped bass. In this study, we estimate requirement l-tryptophan by nonlinear regression analysis several growth indicators. Fifteen isocaloric, isonitrogenous diets were formulated to contain 1.0, 1.3, 1.6, 1.9, 2.2, 2.5, 2.8, 3.1, 3.4, 3.7, 4.0, 5.0, 6.0, 10.0 or 14 g L-tryptophan kg-1 diet and fed reciprocal cross bass 7 weeks. After 5 weeks, survival fish receiving basal was 40% while...
