“…For the proximate composition, the varying levels of protein have significant influence of the whole body composition of P. indicus in terms of crude protein (87.67% ± 0.24%) and crude fat (4.45% ± 0.08%) of CP high and ash (5.88% ± 0.05%) of CP low but none in moisture content of both treatments. These results are in contrast with various studies wherein no significant difference was found in the proximate composition of P. indicus diets in terms of variations in proteins and energy (Vijayagopal et al, 2008), the effect of salinity and dietary protein levels (Kennari & Pagheh, 2007;Lalramchhani et al, 2020).…”

The growth efficiency, productivity and economic viability of Indian white shrimp (Penaeus indicus) fed with diet containing 40% (CP high ) and 34% (CP low ) crude protein (CP) levels were determined in a 90-day grow-out culture trial. Growth parameters including average body weight (ABW), specific growth rate (SGR), survival and feed conversion ratio (FCR) were not statistically different. CP low had lower overall shrimp production (797.53 kg/ha, DOC 90), but was not significantly different from CP high (843.78 kg/ha, DOC 90). The mean values for the water parameters of both treatments, such as DO, pH, salinity, temperature, TAN, NO 2 -N, NO 3 -N and PO 4 -P, also showed no significant differences. However, the TAN values of CP high were consistently higher from day of culture (DOC) 63 and increased significantly (p = .048) at DOC 90. Furthermore, the total bacterial and Vibrio counts in both treatments were not significant throughout the culture period. The economic analysis revealed that CP low obtained higher net profits (6093 USD/ha/year), return on investment (72%) and discounted benefit-cost ratio (1.73). The current study found that feeding a low protein diet to P. indicus is economically viable and profitable and results in improved growth efficiency and productivity while also improving water quality and lowering nitrogen discharge.

“…This dietary regime has been proven effective in promoting shrimp maturation, as documented in research and in actual practice. However, the erratic supply, the unpredictable biochemical content, coupled with the risk of disease agent introduction in the use of this diet, has shifted research interest to understand the biochemical components of polychaete, which enhances explicitly shrimp gonad maturation (Chimsung, 2014; Desrina et al, 2013; Thitamadee et al, 2016; Vijayagopal et al, 2008; Wouters et al, 2001; Xu et al, 2017).…”

Polychaete is considered the best maturation diet for penaeids; however, fluctuating supply and quality warrant detailed studies to understand the specific maturationpromoting factors present in polychaete. Indian white prawn, Penaeus indicus, was fed diets supplemented with different fractions of Marphysa sp. extracts. Fractions, such as the total soluble fraction (TSF), neutral lipid fraction (NLF), and polar lipid fraction (PLF), were incorporated in the maturation diet at 0.25, 0.50, and 1.00% following a 3 × 3 factorial design. One group was fed with basal diet (BD), and another was fed with fresh squid, mussel, and polychaete, serving as the control. After a 30day feeding trial, results showed that the inclusion of polychaete extracts in the diet significantly improved P. indicus maturation compared to groups fed BD and control with 40% maturation rates (MR) (p = 3.4 × 10 −4 ). MR was optimum in groups receiving diets supplemented with ≥0.5% TSF (70.00% ± 0.00) and NLF (60.00% ± 5.77). Similar improved MR was achieved in treatments receiving ≥0.25% PLF supplementation (60% ± 0.00). Accordingly, relative expression of ovarian vitellogenin mRNA of broodstock fed under 0.25 and 0.50% PLF group was 4.44 and 3.96 folds higher than BD, respectively (p = 0.003). No significant differences were detected in the broodstock survival, latency period, hepatosomatic, and gonadosomatic indices. Biochemical content analyses showed no significant differences among the nine treatments except for broodstock's higher ovary protein content in the TSF group (p = 0.037). This study highlights PLF as the most potent component of the polychaete extract in promoting gonad maturation in P. indicus maturation supplemented at a 0.25% optimum inclusion level.
