“…It is reported that dietary protein can influence immune system of crustacea (Bachère, 2000;Pascual et al, 2004). The inclusion of FPH in diet may afford more sufficient digestible protein which could be impacted better into the immune system of fish.…”

Abstract:We investigated the effects of fish protein hydrolysate (FPH) on growth performance and humoral immune response of the large yellow croaker (Pseudosciaena crocea R.). One thousand and two hundred large yellow croakers [initial average weight: (162.75±23.85) g] were divided into four groups and reared in floating sea cages (3 m×3 m×3 m). The animals were fed with 4 diets: basal diet only (control) or diets supplemented with 5%, 10% and 15% (w/w) FPH. The results show that dietary FPH levels significantly influenced the growth and immunity of the large yellow croaker. Compared with the control group, total weight gain (TWG) in all treatment groups, relative weight gain (RWG) and specific growth rate (SGR) in fish fed with diets supplemented with 10% and 15% FPH were significantly increased (P<0.05). Similar results were observed in immune parameters [lysozyme activity, serum complements, immunoglobulin M (IgM)]. Lysozyme activity, complement C4 and IgM were also significantly increased (P<0.05) in fish fed with diets supplemented with 10% and 15% FPH, while complement C3 level was significantly increased (P<0.05) in all treatment groups. In general, with the supplementation of FPH, particularly at dose of 10%, the growth performance and immunity of the large yellow croaker can be improved effectively.

“…In addition, the high rate of fecal production may increase the organic matter content of the hatchery water and generate water quality problems. Pascual et al (2004) observed that L. vannamei fed a low-protein diet (5%) showed increased ingestion rates, reduced growth, high levels of energy lost through waste products and reduced immune function. The authors suggest that the animals compensated for the protein deficiency of their diet by increasing their ingestion rate.…”

“…The energetic parameters were determined as follows (Lemos & Phan 2001;Pascual et al 2004) (1) Energy budget: Energy Ingested (C) = Energy expended in growth (P) + Energy expended in metabolism (R) + Energy expended in excretion (U) + Energy expended in feces (F) + Energy expended in exuviae (E)…”

The aim of this study was to evaluate differences in various physiological measures (growth, fecal production, feed intake, nitrogenous excretion, oxygen consumption, energy substrate used, and energy budget) among males, ovigerous females and non-ovigerous females of the freshwater prawn Macrobrachium amazonicum. This species exhibits pronounced sexual dimorphism and different male morphotypes and has the potential for use in aquaculture. Males and non-ovigerous females were studied for 30 days. Ovigerous females were studied for 10 days. Prawns were fed commercial prawn food, and all males were of the Translucent Claw (TC) morphotype. The results demonstrate physiological differences both between males and females and between females of different reproductive stages. Males had higher rates of ingestion, growth and oxygen consumption and less fecal loss than females. We postulate that in the absence of other morphotypes, TC males may exhibit increased growth rates. Males and females used protein as an energy substrate. Males channeled approximately 9% of their energy budget into growth, whereas non-ovigerous and ovigerous females channeled only 1.4 ± 0.4 and 0.07 ± 0.07%, respectively. Whereas males and non-ovigerous females channeled 9.0 ± 9.74 and 61.8 ± 3.0%, respectively, of the energy ingested into metabolism, ovigerous females channeled 97.7 ± 4.7% into metabolism, likely due to the frequent beating of their pleopods, which oxygenates and cleans the eggs. As reported for marine prawns, males and non-ovigerous females of M. amazonicum lost approximately 5% of their ingested energy in exuviae. The physiological differences observed between the sexes and between females of different reproductive stages might reflect corresponding differences in patterns of activity, growth, and reproduction.

“…Thus both had been named as the important indicators to evaluate shrimp immunological state in many researches [18,19]. Many researches have also shown that innate antimicrobial ability of shrimp relies upon a variety of antimicrobial peptides and proteins that are directly toxic to invading microbes via a strain-specific inhibition mechanism [7,8,20,21].…”

“…The shrimp immune system contained many important solid proteins, such as components of the prophenoloxidase system, superoxide dismutase, acid phosphatase, alkaline phosphatase, lysozyme, antimicrobial peptides and plasma lectins [5e7]. Haemocyanin was the most abundant functional protein of the haemolymph [8]. Recent studies had demonstrated that in addition to its multifunctional role (oxygen transporter, storage protein, carotenoids carrier, osmolite, ecdysone transporter) haemocyanin had a fungistatic [9] and prophenol oxydase-like function [10].…”
