<p>The grouper fish culture was developed after its succesful seed production in hatchery well known. In grow-out culture grouper, the protein requirement and feeding rate have to know well in order to understand the effectiveness on feed utilization . The experiment was designed by factorial design with the first factor as 3 dietary protein (36%, 42%, 48%) and the second factor as 3 feeding rate ( 1,5%, 2,0%, 2,5%). Ten of juvenile tiger grouper (102, 51-102, 73 g of body weight) were stocked in 27 polycarbonate tanks with 400 l volume each. Each tank was equiped with aeration and flow-through water system. Fish was fed three time per day i.e. 08:00, 11:30 and 15:30 Central Indonesia Standard Time for 16 weeks. Every week was measured body weight, survival rate, and feed quantity. The parameter used in this experiment were weight gain, spesific growth rate, feed efficiency and survival rate. The results of the experiment showed that the combination of protein level (36%, 42%, 48%) with feed ratio (1.5%, 2.0%, 2.5%) gave response on growth, weight gain and survival rate.

Completely Randomized Design

The tiger grouper (Epinephelus fuscoguttatus) is an economically important fish whose fry still relies on natural catches. Several species of grouper are very potential to be cultivated because of their fast growth, efficient feed conversion, and high selling value. The purpose of this study is growth performance and survival rate tiger grouper (Epinephelus fuscoguttatus) used different live feed. The research design used in this study was a Completely Randomized Design with 3 treatments 3 replications and continued with LSD test if there were differences. The treatments given are treatment A (Snail), treatment B (Chicken Intestine), and treatment C (Caterpillar Maggot). Parameters observed were length increase, weight gain, survival, feed response, and water quality. The results of this study indicate that the highest increase was found in the treatment of C: 4,04 cm and the lowest was in treatment B: 3 cm, the highest weight gain was found in the treatment of C: 3,73 grams, and the lowest was in treatment B: 2,18 grams. The survival rate for all treatments is 100%. During this study the temperature ranged (28.6-31.8 oC), pH (6.7-8.2), DO (6.3-8.1 ppm), and salinity (23-27 ppt).Keywords: growth, live feed, survival rate, tiger grouper.

Three Nigerian foodstuffs, yellow corn (maize) C(Nig), guinea corn (sorghum) GC, and peanut meal (groundnut cake) PNM were evaluated chemically and biologically in comparison with Canadian yellow corn C(Can) and Canadian soybean meal SBM. Treatments consisted of seven isocaloric (3,600 kcal digestible energy/kg) diets based on combinations of the cereals and protein supplements upon which were superimposed three (20, 16 and 12%) protein levels. Diets were fed to weanling Sprague-Dawley rats for an experimental period of 4 wk. Chemical analyses revealed expected differences in crude protein, fat and amino acids between PNM and SBM. Other than in arginine and phenylalanine, PNM contained fewer essential amino acids than SBM. PNM-supplemented diets resulted in more carcass fat and less carcass lean than SBM-supplemented ones. Although there were no obvious differences in the protein and amino acid composition of the three cereals, there were interactions between these energy sources and the protein supplements. SBM gave its best performance with GC and PNM gave its best performance with C(Can). Supplementation of C(Can)–PNM diet with DL-methionine and L-lysine did not significantly improve gains. Dietary protein level showed an inverse relationship (P < 0.01) to protein and energy digestibilities expressed as percentages, although daily N retention was positively related to dietary protein level. Liveweight gain and empty body weight gain did not give equivalent relative performance to that of dry matter empty body weight gain.

 Best diet of the fish is the sole of production of aquaculture. Growth performance of Clarias gariepinus on the basis of formulated feed supply was carried out from 7th March to 6th May, 2019 in the laboratory of P.G.Campus, Biratnagar in which 130 juveniles (each of 10±0.11 g.) of catfish were cultured in 13 aquaria feeding with treatment diets having crude protein level 35%, 40%, 45% and 50% for treatment and commercial diet for control. There are no significant differences between the water quality parameters and body weight gain (p>0.05) in all treatments. The highest body weight gain (7.31±0.11 g; 65.20%) and SGR (13.051±1.15 g) was observed in fish fed with T C (45% protein level). This value was lowered than value of control(C) i.e. 7.59±0 g; 69.88% and 13.55±0 g respectively. Feed conversion ratio (FCR) was best (13.28±1.89 g) in T D (50% protein level feed). Its value was larger (7.52±1.11 g) in T C than C (7.15±0 g). Mortality rate was highest in T C and C i.e. 30% and lowest in T A and T B i.e. 23.33%. Weight gain of the fish increased with increasing protein level in diet till crude protein level 45% then it was dropped at the diet with protein level 50%. The best weight gain was observed in 7th week having crude protein level 45%. The diet with protein level 45% is suggested for farmers concerning the fish (Clarias gariepinus) in the aquaculture.

Tiger Grouper

Transport in water is the most common method for achieving high survival rates when transporting cultured fish in China; yet, transport success relies on proper water quality and conditions. This research was designed to explore the effects of ascorbic acid and β-1,3-glucan on survival, physiological responses, and flesh quality of farmed tiger grouper (Epinephelus fuscoguttatus) during simulated transport. The transport water temperature for live tiger grouper was 15 °C, which had the highest survival rate, the lowest stress response, and metabolic rate, and this will reduce the susceptibility to diseases. It is stated that β-1,3-glucan influences the changes of cortisol content, heat shock protein 70, IL-1β, and IgM transcription levels during simulated transport. Rather than using ascorbic acid alone (the A-group), β-1,3-glucan (3.2 mg/L) in the presence of ascorbic acid (25 mg/L) can effectively reduce the increase of transport-induced serum cortisol content, heat shock protein 70, and IL-1β, but stimulated IgM. 25 mg/L ascorbic acid and 3.2 mg/L β-1,3-glucan had no obvious effect on the nutritional indexes and flavor of live tiger grouper; however, these can effectively reduce the stress response, improve the innate immune activity, and ensure a higher survival rate.

Ad Libitum Feeding

The effect of the level of dietary protein (5%, 20%, 40% casein by weight) fed for 7 days in an environmental temperature of 22 °C, upon the survival of rats subsequently starved in an environmental temperature of 2 °C was studied. In these experiments ad libitum feeding, isocaloric feeding, and restricted feeding techniques were used, and the effects of thyroidectomy and thyroid feeding were investigated. In all cases, animals provided with the 5% protein diet survived for shorter periods than did those fed the 20% protein diet. In intact rats, but not in thyroidectomized rats, survival time appeared to be inversely related to rate of body weight loss in starvation. Differences in duration of survival among dietary groups are not explicable on the basis of differences in body weight, body composition, or total food intake prior to starvation. The results of experiments using thyroidectomized rats and thyroid feeding suggest that the effect of dietary protein level upon survival in subsequent starvation in the cold are not mediated through the thyroid gland.
