A sixty-days feeding trial was conducted to evaluate the inclusion effect of spirulina Arthrospira platensis meal (SM) in diet on growth and health condition juvenile Pacific white shrimp Litopenaeus vannamei. Four isonitrogenous iso-lipidic experimental diets were formulated contain 0%, 0,2%, 0,4% 0,8% SM. After 60 days, sampled total haemocyte counts measured. The performances significantly a...

The effect of five isonitrogenous diets (36.6% protein), formulated by replacing 0, 25, 50, 75, and 100% of fish meal (FM) with rice protein concentrate (RPC), was investigated on the growth and tail-muscle fatty acid (FA) quality of juvenile Pacific white shrimp, Litopenaeus vannamei. The feeds were fed to shrimp (initial weight of 6.99 ± 0.08 g) five times daily to apparent satiation for 60 d...

the effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. there was no significant difference in final weight (m...

The potential use of poultry by-product meal (PBM) and meat and bone meal (MBM) as alternative dietary protein sources for juvenile Macrobrachium nipponense was studied by a 70-day growth trial. Triplicate groups of M. nipponense (initial body weight: 0.37 g) were fed at 20.7-22.4 degrees C on each of the five isoenergetic and isonitrogenous diets (protein content about 38%) with different repl...

Abstract A supplemental effect of Achyranthes aspera extract (200 mg/kg phytosterol) in diets was evaluated for Pacific white shrimp ( Penaeus vannamei ) on growth performance, digestibility, innate immunity, antioxidant capacity, and disease resistance against Vibrio parahaemolyticus . fish meal soybean meal‐based control diet (Con; protein 38.0% lipid 8.7%) formulated five other were prepared...

Fish meal (FM) has long been considered an essential ingredient for the formulation of shrimp feeds. Until recently, 12%FM was considered a minimum amount, below which weight gain would become reduced due to a reduction in feed intake. In order to test this perceived minimum value, an experiment was conducted on a long-term basis with 4 replicates. Four practical isonitrogenous and isoenergetic...

The shrimp industry in Central America has grown significantly. Much waste is generated by this industry because of the high percentage of shrimp heads, exoskeletons, and soluble components lost during processing. The objective of this study was to measure the effect of substituting different levels of shrimp meal (SM) for soybean meal (SBM) in layer diets. A control corn-soybean layer diet and...

as growth response, vary from 50–55% in Penaeus japonicus, to 40–46% in Penaeus monodon and over 30–60% in Litopenaeus vannamei (Teshima and Kanazawa, 1984; Cousin et al., 1993). Commercial shrimp feeds contain 30–50% crude protein, composed mostly of marine animal protein products such as fish, shrimp and squid meal. These feed materials have high nutritive value and palatability but are expen...
