et al. 2016

To assess the compensatory growth, a 10‐month pond experiment was conducted in which three species of Indian major carps, viz. Catla catla, Labeo rohita and Cirrhinus mrigala (1 : 1 : 1), were stocked at 7500 ha−1 and the fish were subjected to different restricted feeding and refeeding protocols, viz. Control (C): Continuously fed for 10 months; Treatment‐1 (T‐1): Initial supplementary feeding for 2 months+ No supplementary feeding for 1 month + Refeeding for 7 months; Treatment‐2 (T‐2): Initial supplementary feeding for 2 months + No supplementary feeding for 2 months + Refeeding for 6 months; and Treatment‐3 (T‐3): Initial supplementary feeding for 2 months + No supplementary feeding for 3 months + Refeeding for 5 months in triplicate ponds. At the end of experiment, 100% growth compensation was achieved in T‐2 for all the three carp species. Among all treatments, higher weight gain, PER and PPV and lower AFCR were also recorded in T‐2, resulting in maximum fish production. The restricted feeding had significant effect (P < 0.05) on whole body chemical composition of fish. From this study, it is concluded that in 10‐month pond culture of carp in fertilized pond, the T‐2 would be the best and most economic feeding strategy.

Growth compensation in juvenile tongue sole,Cynoglossus semilaevis(Güther, 1873): responses to thermal stress and feed restriction

et al. 2014

Responses of compensatory growth to high temperature and feed restriction in juvenile tongue sole, Cynoglossus semilaevis (G€ uther, 1873), were investigated during a 56-days experiment. Fish were divided into seven groups including three hightemperature treatments which were reared at 28°C for 1, 2 and 3 weeks, respectively, then returned to 22°C (recorded as T1, T2 and T3), three feedrestricted treatments which were fed 25% satiation for 1, 2 and 3 weeks, respectively, then fed ad libitum (recorded as R1, R2 and R3) and a control (continuously reared at 22°C). The results showed that juvenile tongue sole exposed to thermal stress for 1 week exhibited overcompensatory growth. However, complete compensation occurred in T2, T3 and R1 fish, while partial compensation occurred in R2 and R3 fish. The body composition and energy content of fish were not significantly different among all treatments (P > 0.05). The specific growth rate and feed efficiency of fish in T1 were significantly higher than other treatments during the whole experiment period (P < 0.05). Higher feed efficiency and apparent digestion rate during recovery might account for the compensatory growth in tongue sole in the present study. Hyperphagia played an important role in compensatory growth for feed-restricted fish, but was not involved in the compensatory response in thermal stressed fish in the present study. The results from the present study suggested that a suitable thermal stress could be more feasible to elicit compensatory growth than feed restriction in juvenile tongue sole.

“…Sonuçta balıkların son vücut ağırlıkları ve kondisyon faktörleri besleme azaldıkça düşerken spesifik büyüme oranlarında artış görüldüğü bildirilmiştir. Jiwyam (2010) ise P. bocourti türünde yem dönüşüm oranının açlıkla birlikte yükseldiği sonucuna varmıştır. Bu çalışmalarda telafi büyümesi ile beslenen balıklar kontrol grubunun büyüme performansını yakalayamamış ve sonuçları bizim bulgularımızla paralellik göstermiştir.…”

Ege Journal of Fisheries and Aquatic Sciences, 34(4):423-430. doi: 10.12714/egejfas.2017.34.4.09 Öz: Lepistes (Poecilia reticulata), pratikte çoğu zaman düzenli beslemenin uygulanmadığı hatta çoğu günler beslemenin bile yapılmadığı görülen bir süs balığı türüdür. Bu çalışmada, farklı açlık tokluk beslenme döngülerinin lepistes balıklarında cinsiyete göre büyüme ve gelişme üzerine etkileri araştırılmıştır. Çalışma dişi ve erkek bireylerde 3 tekrarlı olarak yürütülmüştür. Başlangıçta ortalama ağırlıkları ve total boyları 0,129±0,025 g ve 2,39±0,20 cm olan dişi ve 0,122±0,019 ve 2,39±0,14 cm olan erkek bireyler 30/50L stok yoğunluğunda kullanılmıştır. Denemede dişi (D) ve erkekler (E) ile ayrı deneme grupları oluşturularak, bu gruplar günde bir (K), bir gün aç bir gün tok (AT) ve iki gün aç bir gün tok (AAT) olarak beslenmişlerdir. Besleme doyana kadar pul yem ile yapılmıştır. Balıklarda büyüme ve gelişim 15 günde bir örnekleme (ağırlık ve total boy) ile 16 hafta boyunca takip edilmiştir. Çalışma sonunda en iyi ağırlık artışı dişi kontrol (KD) grubunda görülürken ATD grubu dişi bireylerde daha az ve AATD, KE, ATE ve AATE gruplarında ise eşit ağırlık artışları görülmüştür (P<0,05). Total boylar arasında anlamlı bir fark görülmese de (P>0,05) en iyi total boy artışı KD ve KE gruplarında görülmüştür, diğer grupların total boy değerleri birbirlerine yakındır. Maliyet analizleri sonucunda ise en karlı besleme KD grubunda saptanmıştır. Sonuç olarak lepisteslerin ticari besiciliğinde en azından günde bir kez beslenmeleri önerilmiştir.

In this study, effects of cycled starvation feeding regimes and gender on growth of guppy were investigated. The study was carried out with three replicates with male and female groups. Female guppies with mean weight of 0.129±0.025 g and mean total lenght of 2.39±0.20 cm and male guppies with mean weight of 0.122±0.019 g and mean total lenght of 2.39±0.14 cm were placed to each aquarium with 30 ind./50 L stocking density. In the experiment, female (D) and male (E) guppies were formed in separate groups, these groups were fed with once a day (K), every other day (AT) and other two days (AAT) starvation cycles. Fish were fed at satiation with flake feeds. Growth and development of fish were measured at every 15 days (weight and total lenght) during 16 weeks. The best weight gain was shown in female control group (KD) while lower in ATD than the KD group and equal weight gain was observed in the AATD, KE, ATE and AATE groups (P<0.05). A significant difference was not appeared between mean total lenghts (P>0.05). The best total lengh...
