Abstract
8-week feeding trial was conducted for juvenile rainbow trout (Oncorhynchus mykiss) to determine the optimal amount of Tenebrio molitor meal (TM) that could replace fishmeal in feeds without reducing growth performance, hematological indices and non-specific immune responses. Five isonitrogenous and isolipidic
diets were formulated with TM...
Aims: In recent years, marine fish farming has been one of the most important aquaculture activities in tropical regions, and their cultivation has grown considerably in most parts of the world. Thus, this study aimed at investigating the effects of different water temperatures on growth performance, biochemical body composition, and hematological...
Silaginidae family fish from Perciforms, are appropriate candidates for shallow water and coastal aquaculture. At least three species of this family represents in the Persian Gulf. Genetic analysis of Sand whiting Sillago sihama , the most common species of family performed using COI gene. During the present study 10 samples were collected from Bus...
Japanese threadfin bream (Nemipterus japonicus) is one of the most important commercial species of fishes in the Persian Gulf. The purpose of this research was to elucidate some features of the sexual cycle and nutritional traits of fish caught in the Persian Gulf (Bushehr province) from September 2012 to September 2013. The total number of 315 fis...
We conducted this study to determine the chronic effects of Azadirachtin on growth parameters, survival and gill morphology of grass carp [Ctenopharyngodon idella (C. idella)] with an average weight of 11.09±2.3 g. We equally distributed 120 fish between three treatments and a control group, with three replicates each. Sublethal concentrations of p...
During the last decade, there has been growing interest in edible or biodegradable films based on biopolymers. Edible films and coatings are of interest since they have potential to improve shelf-life, maintain quality and prevent microbial deterioration and physical damage of foods. In this research, edible films based on red tilapia (Oreochromis...
The effects of dietary nucleotide at 5 levels of 0.0%(Control), 0.15%, 0.25%, 0.35% and 0.5% on the body composition and fatty acids of the grouper, Epinepheluscoioides, with initial weight of 10.70±0.29 g was investigated for a period of 10 weeks. The results indicated improvedgrowth parameters uponadding nucleotide. The best value of growth param...
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)...
The effects of inulin were studied on the growth indices, intestinal morphology as well as fatty acid profile of the Pacific white shrimp, Litopenaeus vannamei with average weight 3.21±0.03 g for 5 weeks. The experiment was carried in triplicate, was conducted in circular PVC tanks of 300 L capacity with 25 shrimp per tank at the Aquaculture Center...
a b s t r a c t Impact of bambara groundnut protein isolate (BGPI) on autolysis and gel properties of surimi from threadfin bream (Nemipterus bleekeri) was investigated. BGPI with trypsin inhibitory activity of 6356.3 AE 6.02 unit/g markedly increased (P < 0.05) the breaking force and deformation of modori gel as the levels used (0e3 g/100 g) incre...
The effects of dietary nucleotide (0.2%) on the growth, intestinal morphology as well as fatty acid profile of the whiteleg shrimp, Litopenaeus vannamei was investigated in Bushehr province (Delvar) for a 5-week feeding trial. The experiment was carried out in triplicate in circular PVC tanks of 300L capacity. Each tank was randomly filled with 25...
Replacement of fish meal (FM) with rice protein concentrate (RPC) as a practical diet for the Pacific white shrimp, Litopenaeus vannamei, was evaluated. Five isonitrogenous (36.6% protein) diets, formulated by replacing 0, 25, 50, 75, and 100% of FM by RPC, were fed to shrimp (initial weight of 6.99 ± 0.08 g) five times daily to satiation for 60 da...
The effects of dietary nucleotide on the growth performance and some hemolymph parameters of the Pacific white shrimp Litopenaeus vannamei were investigated for a 5-weeks feeding trial. The experiment, carried in triplicate, was conducted in circular PVC tanks of 300 L capacity, filled with 200 L of seawater. Each tank was randomly stocked with 25...

... Although previous studies have shown the positive effects of dietary NT on different aspects including physiological, morphological, and microbiological conditions of the gastrointestinal tract in rats (Uauy et al., 1990) and in humans (Bueno et al., 1994), studies on fish, e.g. Atlantic salmon, Salmo salar (Burrells et al., 2001a) and shellfish whiteleg shrimp, Litopenaeus vannamei (Oujifard et al., 2012) have not adequately addressed such aspects. The present study results showed that dietary NT was able to increase the fold and entrocyte height in the mid-intestine in striped catfish, which could lead to a significant increase in total gut surface area and to better absorption capacity. ...
... This work made use of the commercial Lactobacillus plantarum (KC426951) probiotic, which was previously isolated from the intestine of rainbow trout Oncorgynchus mykiss (provided by Zistyar Varna Co, Gilan Province, Iran) (Valipour et al. 2019). To achieve the nal conc. of 2×10 8 CFU kg − 1 of feed (0.2% per 100 g feed), sterile physiological serum (0.9% w/v of NaCl) was mixed in 2 grams of the probiotic (containing 10 8 CFU per 1 g of cells weight) and sprayed on 1kg of a commercial dry feed. ...
... Bambara groundnut protein isolate with trypsin inhibitory activity increased the breaking force and deformation of gels prepared from threadfin bream surimi. Addition of Bambara groundnut protein isolate (2 g/100 g) increased the breaking force and deformation of modori gel from threadfin bream surimi when compared with the control ( Oujifard, Benjakul, Ahmad, & Seyfabadi, 2012). Protein isolates of Bambara groundnut and mung bean enhanced the gel strength of both modori and kamaboko gels from sardine surimi, due to the trypsin inhibitors present in the protein isolates of each bean. ...
