“…Protein merupakan nutrien yang sangat berperan dalam pertumbuhan karena sebagai komponen terbesar dari daging dan berfungsi sebagai bahan pembentuk jaringan tubuh (Halver & Hardy, 2002). Beberapa studi penentuan kebutuhan protein pada ikan perairan tawar sudah banyak dilakukan di antaranya pada benih ikan nila Oreochromis niloticus (Abdel-Tawwab et al, 2010), benih ikan patin Pangasianodon hypophthalmus (Poernomo, 2015), benih ikan baung Hemibagrus nemurus (Suhenda et al, 2010), benih grass carp Ctenopharyngodon idella (Xu et al, 2016;Jin et al, 2015), ikan snakehead Channa (Zhang et al, 2017). Hasil dari penelitian menunjukkan adanya pengaruh kandungan protein pakan terhadap pertumbuhan ikan dan efisiensi pakannya.…”

“…Beberapa penelitian melaporkan bahwa kebutuhan protein pada ikan kerapu Epinephelus sebesar 45%-53% (Jiang et al, 2015;, ikan grass carp Ctenopharyngodon idella sebesar 20%-45% (Jin et al, 2015), ikan nila Oreochromis niloticus sebesar 35%-45% (Abdel Tawwab et al, 2010) dan ikan snout bream Megalobrama amblycephala sebesar 35% (Li et al, 2010).

“…Beberapa penelitian sebelumnya melaporkan hal yang sama, kandungan protein pada pakan tidak memengaruhi nilai sintasan ikan, seperti pada ikan grass carp (Jin et al, 2015), ikan nila (Abdel-Tawwab et al, 2010), kerapu hibrid Rahimnejad et al, 2015), dan teripang (Bai et al, 2016).

ABSTRAKProtein merupakan nutrien yang sangat berperan dalam pertumbuhan ikan. Penelitian ini bertujuan mengetahui kebutuhan protein optimal untuk pertumbuhan ikan Tor tambroides dan pengaruh kandungan protein pakan terhadap efisiensi pakannya. Benih ikan Tor yang digunakan berukuran panjang (1,5 ± 0,1 cm) dan bobot (0,08 ± 0,01 g). Benih ikan dipelihara dalam akuarium berukuran 40 cm x 30 cm x 30 cm dengan ketinggian air 20 cm sebanyak 50 ekor. Selama 40 hari pemeliharaan benih ikan diberi pakan komersil berupa crumble dengan kandungan protein, (A) 25%, (B) 35%, dan (C) 50% sebanyak 20% per hari dari total biomassa ikan, pemberian pakan dengan frekuensi tiga kali sehari. Rancangan penelitian menggunakan rancangan acak lengkap dengan tiga perlakuan dan tiga ulangan. Hasil penelitian menunjukkan ikan Tor tambroides yang diberi pakan dengan kandungan protein sebesar 35% dan 50% memiliki pertumbuhan panjang, bobot, laju pertumbuhan harian (LPH), biomassa, nisbah konversi pakan (FCR), dan efisiensi pakan yang sama (P>0,05) dan berbeda nyata pada pakan dengan kandungan protein 25% (P<0,05).

“…Metabolites reflect the final products of gene expression, but they are also tightly regulated by external environmental influences and thus more closely represent the phenotype of an organism (Patti et al 2012 ). As the molecules of metabolism, differential metabolite profiles can provide important insights into how an organism actually responds metabolically to different situations, such as temperature changes (Dunphy et al 2015 ), variations in salinity (Koyama et al 2015 ), exposure to poor water quality (Ji et al 2015 ), dietary manipulation (Jin et al 2015 ), longterm handling stress (Karakach et al 2009 ), and super-intensive culture conditions (Schock et al 2013 ), among others. Use of metabolomicsbased approaches in aquaculture research is starting to gain tract (reviewed by Alfaro and Young in review; Young and Alfaro in review).…”

Gas chromatography mass spectroscopy was applied to characterize the metabolic profiles of hatchery-reared mussel (Perna canaliculus) larvae before and after a prolonged handling and water exchange process, and to investigate the effect of culture conditions. A decrease in succinate and an increase in alanine were observed after the water exchange, which indicated alterations in energy production and osmotic balance. However, these variations were subtle and it is unlikely that the water exchange practice had any lasting negative effects on larval physiology and performance. Multivariate pattern recognition tools (hierarchical clustering, principal component analysis and projection to latent squares discriminant analysis) were used to assess metabolite variations in larvae reared in low-density static and high-density flow through systems and to construct a culture condition classification model.

“…Since protein is considered to be one of the most important and expensive nutrients in any feed, so that its inclusion in formulated diets should be approached with care. Although protein requirements of cultivable warm water fishes have been already studied by many workers [2][3][4][5][6]] still yet not much information is available on the influence of dietary protein level, isonitrogenous diets with variable protein source and different feeding regimes (ad libitum, 'limited' , and 'starvation' interval) on the growth performance, RNA/DNA ratio, Ca/P ratios and the rates of protein bio-synthesis in the muscle and liver of the Indian climbing perch, Anabas testudineus. Therefore, an effort has been made to determine the correlation with the growth and RNA/DNA, Ca/P ratio and protein bio-synthesis rate.…”

Early fingerlings of Anabas testudineus were nurtured in the laboratory for six weeks under altered nutritional status (different dietary protein level and source) and feeding regimes (ad libitum, 'limited', and 'starvation' intervals). Their RNA/DNA, Ca/P ratios and protein biosynthesis were determined with highly sensitive fluorescence technique, spectrophotometer and liquid scintillation system respectively. Well-fed early fingerlings (4-6 weeks age group) having higher RNA/DNA (2.11), Ca/P (1.82) ratio and protein biosynthesis rates both in muscle and liver have significantly differs from fingerlings with 'limited' food supply and 'starvation' intervals. Rate of protein biosynthesis >244.33 & 603.24 in muscle & liver respectively (count per minute mg protein -1 ) when compared with well-fed fingerlings and reared under 'limited' food supply and 'starvation' intervals. At 'starvation' interval no significant differences were recorded due to different diet treatment. However, fingerlings showed higher mortalities, decreased growth, RNA/DNA, Ca/P ratio and protein biosynthesis rate that may be caused by malnutrition. Fingerlings (early) sampled after 42 days in nearby areas during late monsoon (September) showed RNA/DNA, Ca/P ratio and protein biosynthesis rate were surprisingly low almost as low as 'starved' fingerlings, when judged on the basis of mean body weight as compared to well fed fish. It was also observed under microscope that some of these fingerlings were seriously affected by an intestinal disease and this may be due to the ingestion of unsuitable copepods. The low RNA/DNA, Ca/P ratio and protein biosynthesis rate in field samples and 'starved' fish are, therefore, interpreted as a sub-lethal result of this disease and malnutrition respectively.
