“…Feed intake was found to decrease when dietary lipid exceeded 12 % in our study, and it seemed that fish fed to satiation can adjust feed intake in order to satisfy their digestible energy requirements (Cho and Kaushik 1985;Kaushik and Medale 1994). Although lipid intake and lipid gain increased with the increase in dietary lipids, the low LRE, an indicator of poor lipid retention, showed by fish fed with D15 follows the same trend of teleost pejerrey Odontesthes bonariensis, when fed lipid levels higher than 25 % (Gómez-Requeni et al 2013). Betancor et al (2011) reported that HUFA (mainly DHA) was readily deposited in fish tissues and associated with higher sea bass mortalities because of increased peroxidation risks, and dietary DHA contents up to 5 % severely increased the incidence of muscular lesions and the presence of ceroid pigment within hepatocytes.…”

“…The increase in dietary lipids significantly improved PER in our study, revealing that increasing the dietary lipids will provide a more efficient utilization of dietary protein for growth purposes (Lee et al 2002). As weight gain involves fat deposition and is not only the result of protein retention, it may not always be considered an accurate predictor of true growth (Gómez-Requeni et al 2013). Therefore, the higher PRE reflected the better protein utilization for growth purposes in fish fed with D12.…”

The present study aimed at determining the growth performance, feed utilization, body composition and antioxidant status of chu's croaker (Nibea coibor) juveniles fed with increasing levels of dietary lipid: 6 % (D6), 9 % (D9), 12 % (D12) and 15 % (D15). Each diet was assigned to triplicate groups of fish in a total of 12 floating pens (300 fish, 25 fish per pen). After a 49-day growth trial, survival rate was not affected. D12 and D15 led to significantly higher specific growth rate (SGR). Fish fed D12 showed the highest protein efficiency ratio (PER), protein and lipid retention efficiencies (PER and LRE, respectively). The hepatosomatic and viscerosomatic indexes (HIS and VSI, respectively) increased, while feed conversion ratio (FCR) and feed intake (FI) decreased. Body protein, ash and muscle lipid contents were not significantly affected, but significantly higher body and liver lipid were noticed in fish fed with D15. Monounsaturated fatty acid (MUFA) was found to decrease compared to the experimental diets in muscle, while high unsaturated fatty acid (HUFA) was selectively accumulated in all treatments. Serum alanine transaminase (ALT, 14.13-22.53 U/L), aspartate transaminase (AST, 34.31-51.25 U/L), cholesterol (CHO, 2.02-3.03 mmol/L) and triglyceride (TG, 5.61-8.50 mmol/L) were correlated with increasing dietary lipids. Liver malate dehydrogenase (MDA, 3.32-6.67 mmol/L) and superoxide dismutase (SOD, 42.69-52.86 U/mg prot) increased with dietary lipids, while total antioxidant capacity (t-AOC, 1.08-3.50 U/mg prot) decreased. Polynomial regression analyses between SGR and dietary lipid levels showed that the optimal dietary lipid requirement of chu's croaker is 12.9 % of dry matter.

“…Thus, these results suggested that dietary lipid could partially spare protein, meanwhile, the low-protein and highlipid diet could improve the intestinal health status of fish. However, in fish, it was proved that endogenous lipase activities were limited [24] and high levels of dietary lipid decreased the efficiency or activity of endogenous lipase, resulting in poor digestion of lipids [59,60]. Therefore, we speculate that exogenous lipase supplementation may improve intestinal health through elevating lipids digestion in the intestine of fish, which need to be investigated.…”

In this study, the effects of different salinity levels (9,12,15,18,21,24,27,30, and 33) on the growth performance, body composition, antioxidant indexes of Perinereis aibuhitensis (initial average mass, 20.4 ± 0.3 mg) and total nitrogen in the substrate were investigated. The survival rate, specific growth rate, feed coefficient, and protein efficiency ratio under different salinity levels were measured. The results showed that the survival rate of P. aibuhitensis at the salinity level of 9 was significantly lower than that of P. aibuhitensis at other salinity levels (P < 0.05). However, the survival rate of P. aibuhitensis at other salinity levels was not significant (P > 0.05). On the basis of quadratic polynomial fitting of the relationship between salinity levels and the specific growth rate, feed coefficient, and protein efficiency ratio, it was concluded that 25.36 -25.9 is the most suitable salinity range for the growth performance of P. aibuhitensis. The main body composition (moisture, crude fat, crude protein, and ash content) was measured at different salinity levels. The results indicated that, with the increase in salinity, the moisture content of P. aibuhitensis decreased gradually; in contrast, the ash content increased gradually, as the salinity level increased. However, in the salinity range of 18 to 33, the difference in ash content was not significant (P > 0.05). Salinity had a significant influence on the crude protein content (P < 0.05), while it had no significant influence on crude body fat. Crude protein showed an increasing trend with the salinity increasing from 9 to 24, and decreased with the salinity increasing from 24 to 33. Antioxidant indexes such as superoxide dismutase, catalase, vo MDA content was as low as the antioxidant activity at the salinity level of 24; this means low in vivo contents of active oxygen free radicals and excellent growth performance. This conclusion is consistent with that for other growth indexes. The total nitrogen content of the substrate in which the P. aibuhitensis specimens were cultured for 60 days was higher than the total nitrogen in the soil. With an increase in salinity, the total nitrogen content first decreased and then increased, and the lowest value was observed at the salinity level of about 24.
