Selection of diet for culture of juvenile silver pomfret, Pampus argenteus

Abstract

Juvenile silver pomfret, Pampus argenteus, was grown in culture tanks for 9 weeks on four different diets, and their effects on fish growth, digestive enzyme activity, and body composition were assessed. The feeding regime was as follows: Diet 1: fish meat; Diet 2: fish meat+artificial feed; Diet 3: fish meat+artificial feed+Agamaki clam meat; Diet 4: fish meat+artificial feed+Agamaki clam+copepods. The greatest weight gain was associated with Diet 4, while the lowest weight gain was associated with Diet 1. No significant difference was observed in weight gain between fish receiving Diet 2 and Diet 3. Specific growth rate followed similar trends as weight gain. The feed conversion ratio (FCR) of fish fed Diet 1 was significantly higher than the other fish groups, but no significant differences were observed in FCRs of fish fed Diet 2, Diet 3 or Diet 4. There was also no significant difference in the hepatosomatic index (HSI) between the four diets. For fish that received Diets 2-4, containing artificial feed, higher protease activities were detected. A higher lipid content of the experimental diets also significantly increased lipase activities and body lipid content. No significant differences in amylase activity or body protein content were found between Diets 1-4. In conclusion, a variety of food components, including copepods and artificial feed, in the diet of silver pomfret significantly increased digestive enzyme activity and could improve growth performance.

Effect of high-dose vitamin C supplementation on growth, tissue ascorbic acid concentrations and physiological response to transportation stress in juvenile silver pomfret, Pampus argenteus

“…The basal diet was formulated (Table ) to contain about 46% crude protein and 12% lipid, which have been shown to be sufficient to support the optimal growth of silver pomfret (Hossain et al., ; Peng et al., ). L‐Ascorbyl‐2‐polyphosphate (35% ascorbic acid equivalent, SAMP, China) was supplemented separately to the basal diet at 0, 1000 and 2000 mg kg −1 to obtain concentrations of 100, 450 and 800 mg ascorbic acid/kg diet, respectively.…”

“…Silver pomfret ( Pampus argenteus ) is a new candidate species for aquaculture in China, Kuwait, India and Japan, (James and Almatar, ; Hossain et al., ; Peng et al., ). Based on the hypothesis that high doses of vitamin C could reduce stress in silver pomfret, the purpose of this study was firstly, to estimate the effect of high‐dose vitamin C supplementation on growth and tissue ascorbic acid concentrations; secondly, to estimate the effect of high‐dose vitamin C supplementation on physiological response to transportation stress in juvenile silver pomfret.…”

Recent advance on aspect of fisheries: A review

“…This species has distribution in Persian Gulf, Oman Sea, Japan, Malaysia, Indonesia, southern and eastern coasts of China, the West and Southwest Korean Peninsula and the Indian Ocean [26,27] and is popular species in these regions. So far extensive studies in the field of silver pomfret (P. argenteus) culture have been done; however, this technique is not complete [53,54]. High mortality rate of larvae and problems of natural reproduction of broodstock in capacity condition, are main issues of this species culture [51]; however, progress achieved in recent years in addition to the popularity of this species in middle east of Asia and worldwide, no cannibalism and suitable eating of artifact diet lead to offer this species as a new candidate to mariculture industry [45].…”

Dietary n-3 LC-PUFAs affect lipoprotein lipase (LPL) and fatty acid synthase (FAS) activities and mRNA expression during vitellogenesis and ovarian fatty acid composition of female silver pomfret (Pampus argenteus) broodstock

“…Silver pomfret ( Pampus argenteus ) is a novel aquaculture species in China (Peng et al . , ). In spite of significant technical developments and intense research in silver pomfret, certain limitations have hindered the applications of this fish species.…”

“…; Peng et al . , ), little information is available on the effects of diet on the physiological and biochemical responses of broodstock. The maturation cycle of silver pomfret broodstock requires large quantities of macronutrients (e.g.…”
