The nutritional management of barramundi, Lates calcarifer– a review

Barramundi nutrition research has been undertaken since the 1980s. From that time to the present, the requirements for most nutrients, energy demand, ingredient utilization and the effects of nutrition on flesh quality aspects have all been examined to varying extents. Optimal protein content of diets has been shown to vary with diet energy density and also the size of fish that are being fed. Most studies have suggested a protein requirement from 450 to 550 g kg^?1. For small fish, a protein to energy ratio of 25 to 30 g MJ^?1 is suggested. Limited work has been carried out on fish larger than 500 g. The 10 essential amino acids for other fish are also considered to be required by barramundi. Proportional requirements have been identified for methionine, lysine and arginine. Protein utilization efficiency by barramundi has been estimated at 46% efficiency. Iteratively determined protein and amino acid requirements suggest that the requirement for protein and amino acids will decrease with increasing fish size and are largely consistent with empirically determined requirements. Lipid requirements for energy and essential fatty acids (EFAs) show that smaller fish performed the best with a dietary lipid level of 140–160 g kg^?1, while growth of larger fish continued to improve with lipid levels up to 190 g kg^?1, although no higher levels were examined. EFA requirements have been identified for long‐chain n‐3 fatty acids and minimum levels of 10 g kg^?1 have been indicated. An optimal ratio of n‐3 to n‐6 fatty acids of 1.5 to 1.8:1 was also suggested. Barramundi have shown limited capacity to utilize dietary carbohydrates for energy, with starch digestibilities below 30% at even low inclusion levels. Barramundi also exhibit limited glycaemic control, being unable to rapidly reduce blood glucose levels. Requirements have been demonstrated for several key vitamins and quantitative requirements determined for varying forms of ascorbic acid (vitamin C). Quantitative requirements have also been established for pyridoxine and pantothenic acid but only qualitative assessments for other key vitamins. Few mineral requirements have been identified. Phosphorus is the only mineral to be studied and a requirement between 5.5 and 6.5 g kg^?1 is suggested. Energy demands of barramundi have been shown to be largely driven by thermodynamic demands on metabolic requirements and the demand for somatic energy deposition. Energy utilization by barramundi has been estimated as 68% efficient. Energy demands for maintenance are shown to be related to liveweight by an exponent of about 0.8. Variations in temperature are shown to vary the maintenance energy requirement but do not affect the efficiency of energy utilization. Feed management through feed specification selection has been shown to be possible through selection of feed protein and energy content based on the fish's change in somatic energy density. Typically, this leads to the use of lower protein and higher energy density feeds with larger fish. Ration allocation based on changes in fish size and temperatures has been studied from both iterative and empirical perspectives, and tables were developed based on these findings. Several key feed ingredients have been evaluated for their digestibility, palatability and energy and nutrient utilization. Among those ingredients were meat meals, lupin kernel meals, soybean meals and some plant oils. Limited effects of feed ingredients on flesh quality have been noted, although some effects of diet nutrient and energy specifications have been noted.

软骨鱼类染色体研究进展

在各类脊椎动物中，软骨鱼类是开展染色体研究最少的类群。迄今为止，文献共报道了70种软骨鱼的核型，仅占现生838种软骨鱼类的8．35％，包括31种鲨类，37种鳐类和2种全头类。已报道的软骨鱼类二倍体染色体数为52～104（巴西双鳍电鳐二倍体染色体数为28例外），常存在微染色体。在不同的分类阶元，相对原始的软骨鱼类具有较多的染色体数，端部和亚端部着丝粒染色体较多，多有微染色体。软骨鱼类染色体进化趋势表现为个体染色体数目的减少。中部和亚中部着丝粒染色体数目的增多，并伴随微染色体的消失。软骨鱼类是核DNA含量较大的脊椎动物。已报道144种软骨鱼类的核DNA含量，其变化较大，为3．0～34．1pg／N，全头类的核DNA含量最小，角鲨目和扁鲨目的核DNA含量最大。近年来，在软骨鱼类染色体的C带、核仁组织区（NOR）染色、限制性内切酶显带、特异DNA探针如端粒序列和短散布重复序列（SINE序列）的荧光原位杂交等方面取得了较大进展。现代分子生物学技术也被用于一些软骨鱼类的基因组研究，在重复DNA序列、随体DNA家族和微卫星位点等方面均取得一些成果。
