“…Santiago et al. () used 6‐ to 24‐month stunted bighead carp juveniles in cage culture and reported partial CG activity in only the 6‐ to 18‐month stunted groups. Similarly, Prabhakar, Sardar, and Das () observed CG and hyperphagia in rohu fingerlings subjected to 3‐ and 7‐day food deprivation followed by re‐feeding for the same period, while the same was absent in the 15‐ and 25‐day cycles.…”

“…Chakrabarti, Sarkar, andGhosh (1990) (in Hossain et al, 2003) reported retarded growth in 6-month overwintered mrigal during a subsequent grow-out phase, whereas overwintered rohu were unaffected. Santiago et al (2004) used 6-to 24-month stunted bighead carp juveniles in cage culture and reported partial CG activity in only the 6-to 18-month stunted groups.

“…() in their review of cyprinids have reported full, partial, as well as no CG responses. Stunted juveniles of bighead carp Aristichthys nobilis (Richardson 1845) have shown lower weight and length attainment in the grow‐out phase (Santiago, Gonzal, Aralar, & Arcilla, ), while in another cyprinid, rohu Labeo rohita (Hamilton, 1822), stunted juveniles exhibited a CG response in the subsequent grow‐out phase under polyculture (Hossain, Little, & Bhujel, ). Such reports, in favour and against the CG response in cyprinids, present an ambiguity on the existence of the phenomenon in stunted rohu, the important Indian major carp.…”

Summary Rohu Labeo rohita juveniles stunted for 2, 4, 6, 8 10 and 12 months at 20 and 40 m−3 densities were subsequently cultured for 1 year in six grow‐out earthen ponds each 0.09 ha. Each pond was stocked with juveniles stunted for a particular duration (treatment) at a combined density of 8,000 ha−1 from two density groups at a 1:1 ratio. Electronic tags were implanted in 20 juveniles of each density group in all treatments as sub‐samples to track fish growth per individual. Another grow‐out study evaluated the growth of a fresh batch of rohu juveniles against similar sized but stunted 12‐month‐old juveniles, stocked together at 8,000 ha−1 density (1:1). Thirty juveniles from each group in this pond were tagged. After the year‐long grow‐out phase, survival (85.6%–96.3%) showed a positive correlation with the juvenile stunting duration. The study revealed a minimal influence of stunting density on juvenile growth in a subsequent grow‐out phase when they were stunted up to 8 months. But a higher stunting density (40 m−3) favoured growth in juveniles stunted for longer periods (>8 months). Growth curves of the lower and higher stunting density groups as well as “all rohu populations” in the treatments showed convergence with those of control (2 months stunted) only in the 4‐month stunted juveniles. The growth convergence in this treatment was achieved within 6 months of culture and subsequently surpassed that of control to over‐compensate at the end of 12 months of culture. No such compensatory growth (CG) response was observed in the 6‐ to 12‐month stunted rohu, because the growth curves run almost parallel to each other. The study also revealed juvenile stunting for more than 6 months delayed the initiation of the growth recovery process in the stunted individuals during their subsequent grow‐out phase. In the second study, identical growth trajectories of the fresh batch and the year‐long stunted juveniles reaffirmed a non‐existence of CG activity in the later. Such results indicate that juvenile stunting in rohu for 6 months and beyond does not lead to a better fish yield or economic gain to farmers, but rather adds to the investment costs because of the need for more feed and maintenance during stunting.

This study aimed to evaluate the growth of stunted elver Anguilla bicolor from three different periods of stunting process. Prior to experiment, the stunting process of elver was carried out by limiting the feeding rate at 2% of the fish biomass and temperature media with 24 oC for 2, 4, and 6 months period. The study used a completely randomized design with three different sources of stunted elvers (i.e., A = 2 months; B = 4 months; C = 6 months) as treatments with three replications. Measurement of RNA:DNA ratio, protein content, profile blood description and elver otolith growth was carried out at the beginning and end of rearing process. Post-stunting elvers were reared on artificial media designed according to elver habitat and controlled. Elver was stocked with 15 individuals in the artificial semi-natural media with a temperature of 28 oC and fed with 1 kg media-1 day-1 tubifex worm for three months. The results showed that the compensatory growth of stunted elvers increased two to three times with 100% of survival rate after three months of rearing process. Stunting has a significant effect on treatment B, indicated by the value of weight specific growth rates, RNA : DNA ratio, protein content, blood glucose levels and otolith growth of elvers. This study revealed that the growth performance of stunted elver reared in semi-natural media for four months is better than other treatments.

ABSTRACT The aim of the research was to determine feed requirement for the maintenance, optimum, and maximum growth of freshwater eel (Anguilla bicolor bicolor) seed (1–2 g body weight). Feed used in this research was KRA feed with 46% protein content, with different feeding level (FR) at 0%, 5%, 10%, and 15% of fish biomass. The experiment was conducted in 30 days. Parameters measured were survival and specific growth (SGR). The results showed that survival of fish in all treatments were 100%, except in fish fed on 15% of biomass (only 96). Fish growth with feeding of 0%, 5%,10%, and 15%, were -1.06%; 0.42%; 0.73%; and 0.19%, respectively. Based on the analysis of the relationship between feeding level and growth, the feed requirement for maintenance, optimum, and maximum growth in 1–2 g freshwater eel seed were 3.3%; 7.0%; and 9.5% of the biomass, respectively. Keywords: eel seed, feed requirement, growth ABSTRAK Penelitian dilakukan dengan tujuan untuk mendapatkan kebutuhan pakan untuk maintenance, dan untuk pertumbuhan optimum serta maksimum benih ikan sidat (Anguilla bicolor bicolor) (bobot tubuh 1–2 g). Pakan yang digunakan pada penelitian ini adalah pakan KRA dengan kadar protein 46%, dengan tingkat pemberian pakan 0%, 5%, 10%, dan 15% dari bobot biomassa ikan. Pemeliharaan berlangsung selama 30 hari. Parameter yang diukur meliputi sintasan (STS) dan laju pertumbuhan spesifik (LPS). Hasil penelitian menunjukkan bahwa STS benih ikan sidat selama pemeliharaan, memiliki nilai yang baik (100%) kecuali pada pemberian pakan 15% (hanya 96%). Laju pertumbuhan benih ikan sidat selama pemeliharaan dengan pemberian pakan 0%, 5%, 10%, dan 15% berturut-turut adalah -1,06%; 0,42%; 0,73%; dan 0,19%. Berdasarkan analisis hubungan antara tingkat pemberian pakan dan laju pertumbuhan spesifik, maka kebutuhan pakan maintenance, pertumbuhan optimum dan maksimum benih ikan sidat berukuran 1–2 g berturut-turut adalah 3,3%; 7%; dan 9,5% dari biomassa. Kata kunci: benih ikan sidat, kebutuhan pakan, pertumbuhan
