“…While data on protein requirements for maintenance are available for a few freshwater (Kaushik et al 1981;Kaushik & Luquet, 1984) and marine species (Lupatsch et al 1998), data on the maintenance requirements for IAA are scarce. For estimating the AA requirements for maintenance of pigs, Fuller et al (1989) proposed a linear model based on the relationship between AA intake and N gain.…”

Besides being an indispensable amino acid for protein synthesis, arginine (Arg) is also involved in a number of other physiological functions. Available data on the quantitative requirement for Arg in different teleosts appear to show much variability. So far, there are very limited data on the maintenance requirements of indispensable amino acids (IAA) in fish. In the present study, we compared N and Arg requirements for maintenance and growth of four finfish species: rainbow trout (Oncorhynchus mykiss ), turbot (Psetta maxima ), gilthead seabream (Sparus aurata ) and European seabass (Dicentrarchus labrax ). Groups of fish having an initial body weight close to 5 -7 g were fed semi-purified diets containing graded levels of N (0 to 8 % DM) and Arg (0 to 3 % DM) over 4 to 6 weeks. For each species, N and Arg requirements for maintenance and for growth were calculated regressing daily N gain against daily N or Arg intakes. N requirement for maintenance was estimated to be 37·8, 127·3, 84·7 and 45·1 mg/kg metabolic body weight per d and 2·3, 2·2, 2·6 and 2·5 g for 1 g N accretion, in rainbow trout, turbot, gilthead seabream and European seabass respectively. The four species studied appear to have very low or no dietary Arg requirements for maintenance. Arg requirement for g N accretion was calculated to be 0·86 g in rainbow trout and between 1·04-1·11 g in the three marine species. Turbot required more N for maintenance than the other three species, possibly explaining its reputedly high overall dietary protein requirement. Data suggest a small but sufficient endogenous Arg synthesis to maintain whole body N balance and differences between freshwater and marine species as regards Arg requirement. It is worth verifying this tendency with other IAA.

“…However, the value for DE efficiency (0.27) was lower than that in studies on other fish species. For example, in gilthead seabream (Sparus aurata) the efficiency of utilisation of DE and DP for growth were 0.54 and 0.34 respectively (Lupatsch et al, 1998).…”

“…Nutrient requirements in fish are normally quantified by a dose-response relationship, where diets containing graded levels of a nutrient are fed and the growth is measured (Lupatsch et al, 1998). Once the optimal requirement for a nutrient is determined this is provided in the feed.…”

Abstract-A study was conducted to find a suitable diet and feeding level for the culture of milkfish (Chanos chanos) in Zanzibar. Two growth trials and one digestibility trial were done. The first growth trial was conducted using 25, 32 and 40% protein diets to determine the optimal level that could be used for the second growth trial on feeding levels. There were no significant differences on feed intake and growth performance of milkfish among the treatments (P<0.896). Body composition analysis showed that fish had more fat (lipid) when fed 32 than 25 and 40% protein diets. The digestibility of protein increased with increasing protein levels: it was 87.3, 92 and 93% respectively. There were no significant differences among the diets (P<0.291). The 32% protein diet was chosen for the second growth trial to test a suitable feeding level. Milkfish were fed at 0, 0.8, 1.6, 2.4, 3.2 and 4% of their body weight. There was a significant linear relationship (r 2 = 0.79) between digestible energy fed and energy gain, digestible protein fed and protein gain among protein and feeding levels. Protein and energy efficiency were 0.37 and 0.27 respectively. Results of growth, protein and energy efficiency and utilisation indicate that the suitable level of milkfish feeding was 4% of body weight per day when a 32% protein level was used.

“…The optimum dietary protein content for good performance depends on the energy content of food (Cowey, 1979;Salhi et al, 2004). An optimal dietary protein to energy ratio (E/P) is important because any excess or defi ciency of non-protein energy results in lower protein and energy utilization and may also depress fi sh growth performance (Shiau and Peng, 1993;Lupatsch et al, 1998;Ali and Jauncey, 2005;Tibbetts et al, 2005). The E/P ratio has been studied for several species such as channel catfi sh (Garling and Wilson, 1976), Nile tilapia (ElSayed and Teshima, 1992), Asian seabass (Catacutan and Coloso, 1995), and grouper (Shiau and Lan, 1996).…”

A bstractAn 8-week feeding trial was conducted to detect the optimal dietary protein and energy, as well as the eff ects of protein to energy ratio on growth, for the rare minnow ( Gobiocypris rarus ), which are critical to nutrition standardization for model fi sh. Twenty-four diets were formulated to contain three gross energy (10, 12.5, 15 kJ/g), four protein (20%, 25%, 30%, 35%), and two lipid levels (3%, 6%). The results showed that optimal dietary E/P was 41.7-50 kJ/g for maximum growth in juvenile rare minnows at 6% dietary crude lipid. At 3% dietary lipid, specifi c growth rate (SGR) increased markedly when E/P decreased from 62.5 kJ/g to 35.7 kJ/g and gross energy was 12.5 kJ/g, and from 75 kJ/g to 42.9 kJ/g when gross energy was 15.0 kJ/g. The optimal gross energy was estimated at 12.5 kJ/g and excess energy decreased food intake and growth. Dietary lipid exhibited an apparent protein-sparing eff ect. Optimal protein decreased from 35% to 25%-30% with an increase in dietary lipid from 3% to 6% without adversely eff ecting growth. Dietary lipid level aff ects the optimal dietary E/P ratio. In conclusion, recommended dietary protein and energy for rare minnow are 20%-35% and 10-12.5 kJ/g, respectively.
