Abstract:
... A 12-week feeding trial was conducted to determine the dietary valine requirement of fingerling Catla catla (3.50 ± 0.15 cm, 0.63 ± 0.04 g). Seven casein gelatin-based diets (33% crude protein; 3.34 kcal/g digestible energy) containing graded levels of valine (0.51%, 0.69%, 0.91%, 1.12%, 1.31%, 1.49%, 1.71% dry diet) were fed to triplicate groups of fish to apparent satiation at 08:00, 12:30, and ...
... Five different levels (0, 25, 50, 75, and 100 g kg ⁻¹) of algal (Ulva fasciata) meal were added to red tilapia feeds to examine its effect on growth and carcass biochemical content. Addition of ulva meal significantly improved growth performance, feed utilization, total crude protein content, and percentage of highly unsaturated fatty acids. Fish fed 75 g kg ⁻¹ or 100 g kg ⁻¹ of U. fasciata perfor ...

Abstract:
... The purpose of this study was to examine the effect of some immunostimulants and probiotics on the survival rate, final weight, and disease resistance of overwintered tilapia fry. There were five treatments: T1 (control) fed a balanced diet (35% protein) without additives. Treatments 2 to 5 were fed diets supplemented with 4% garlic, 4 g/kg Echinacea, 4 g/kg Organic Green or 4 g/kg Vet-Yeast, resp ...
... The aim of this study was to provide new insights into the stability in water of the prepared feeds for echinoculture. The stability tests of four prepared feeds were carried out in laboratory in two different trials corresponding to different temperature levels (24°C and 19°C) and four different times of immersion (up to 72 h). Temperature and duration of immersion significantly affected the stab ...
... Three 28% protein feeds (premium, standard, or a low-cost diet) were fed to channel catfish in a pond study to compare growth, production, and costs as a follow up to similar work with 32% protein feeds. Twelve 0.1-ha earthen ponds at the University of Arkansas at Pine Bluff (UAPB) Aquaculture Research Station were stocked with carryover fish (0.39 kg mean weight) at 5,860 fish/ha and fingerling c ...

Abstract:
... We compared performance (growth, survival, condition, and health indices) of largemouth bass, Micropterus salmoides, fingerlings (10.3 g [SE ± 0.5 g] and 92 mm [SE ± 1 mm] total length) fed one of four commercial grower feeds: Purina Aquamax Grower 400 (PAG; PMI Nutrition International LLC), Bio-Oregon BioDiet Grower (BDG; Bio-Oregon), Silver Cup Steelhead (SCS; Silver Cup), and Richloam Bass Fry ...
