Abstract
A 20 week feeding with three dietary protein levels (40, 45 and 50%) and four dietary energy levels (18.5, 19.8, 22.1 and 22.4 MJ kg−1) by range (P/E) ratios of 17.86–26.85 mg protein kJ−1 was conducted to investigate optimum protein, energy and protein to energy (P/E) for final weight (FW), specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER) and Hepatosomatic index (HSI) Acipenser persicus Fingerling (Average weight 10.26 ± 0.11). Study was carried out in 3 × 4 factorial design. Acipenser persicus Fingerlings reared in fiberglass tank (500 L water volume) and fed to apparent satiation fourth daily. At the end of the experimental period six fish were sampled randomly from each replicate, killed and were preserved at −20°C for body composition analysis and Hepatosomatic index. The same energy level, increase in dietary protein from 40 to 45% resulted in significant increases in the final weight (FW) and Increase in protein levels from 40 to 45 and 50% led to a significant increase in (PER) Protein efficiency ratio fishes (P < 0.05). At similar protein levels, increasing energy from 18.5 MJ kg−1 to higher levels (21.1 and 22.4 MJ kg−1) resulted in a significant increase in W2 and PER values and an improvement of FCR (P < 0.05). Highest FW belonged to fish fed diet 7 (45% protein and 21.1 MJ kg−1) followed by fish fed diet 8 (45% protein 22.4 MJ kg−1) and fish fed diet 4 (40% protein and 22.4 MJ kg−1). Increase in dietary energy level from 18.5 to 24.4 MJ kg−1 resulted a accumulation of lipid in carcass. The highest body lipid and protein showed in fishes fed diet 3 (40% protein and 22.1 MJ kg−1) and 4 (40% protein and 22.4 MJ kg−1). The present study showed that diets containing 40% protein and 20.1–25.9% lipid with a P/E ratio of 17.86 mg kJ, prepared from good quality ingredients can meet the dietary requirements of A. persicus fingerlings without leaving adverse effects on the biochemical composition of the body.

Study was carried out in 3 × 4 factorial design. Acipenser persicus Fingerlings reared in fiberglass tank (500 L water volume) and fed to apparent satiation fourth daily. At the end of the experimental period six fish were sampled randomly from each replicate, killed and were preserved at −20°C for body composition analysis and Hepatosomatic index. The same energy level, increase in dietary protein from 40 to 45% resulted in significant increases in the final weight (FW) and Increase in protein levels from 40 to 45 and 50% led to a significant increase in (PER) Protein efficiency ratio fishes (P < 0.05). At similar protein levels, increasing energy from 18.5 MJ kg−1 to higher levels (21.1 and 22.4 MJ kg−1) resulted in a significant increase in W2 and PER values and an improvement of FCR (P < 0.05). Highest FW belonged to fish fed diet 7 (45% protein and 21.1 MJ kg−1) followed by fish fed diet 8 (45% protein 22.4 MJ kg−1) and fish fed diet 4 (40% protein and 22.4 MJ kg−1). Increase in dietary energy level from 18.5 to 24.4 MJ kg−1 resulted a accumulation of lipid in carcass. The highest body lipid and protein showed in fishes fed diet 3 (40% protein and 22.1 MJ kg−1) and 4 (40% protein and 22.4 MJ kg−1). The present study showed that diets containing 40% protein and 20.1–25.9% lipid with a P/E ratio of 17.86 mg kJ, prepared from good quality ingredients can meet the dietary requirements of A. persicus fingerlings without leaving adverse effects on the biochemical composition of the body.</abstract><relatedItem type="host"><titleInfo><title>Journal of Applied Ichthyology</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">0175-8659</identifier><identifier type="eISSN">1439-0426</identifier><identifier type="DOI">10.1111/(ISSN)1439-0426</identifier><identifier type="PublisherID">JAI</identifier><part><date>2011</date><detail type="title"><title>Proceedings of the 6th International Symposium on Sturgeon Wuhan, China October 25‐31, 2009</title></detail><detail type="volume"><caption>vol.</caption><number>27</number></detail><detail type="issue"><caption>no.</caption><number>2</number></detail><extent unit="pages"><start>737</start><end>742</end><total>6</total></extent></part></relatedItem><identifier type="istex">CB47DC3148F6309F9890D0C5613436094DAE32EE</identifier><identifier type="DOI">10.1111/j.1439-0426.2010.01636.x</identifier><identifier type="ArticleID">JAI1636</identifier><accessCondition type="use and reproduction" contentType="copyright">© 2011 Blackwell Verlag, Berlin</accessCondition><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Publishing Ltd</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
