Metamorphosis is a critical developmental stage that presents particular challenges in fish aquaculture. The sharp increase in mortality that accompanies this transformation has often been attributed to nutritional deficiencies. Providing live feed (the rotifer Brachionus plicatilis Müller, 1786 and the brine shrimp Artemia salina (Linnaeus, 1758)) during the larval stages is costly and labour intensive, which explains why much effort has been put on early weaning. However, previous observations in winter flounder (Pseudopleuronectes americanus (Walbaum, 1792)) indicate that juveniles weaned after settlement had better survival than those weaned at the larval stage. In this study, we tested whether late weaning (at settlement (W0) and groups maintained on co-feeding for 1 month (W1), two months (W2), or 3 months (W3) after settlement) could improve juvenile survival and lipid composition. Our results demonstrated that maintaining co-feeding beyond the larval stage was essential for after-settlement survival. Juveniles co-fed until 90 days after settlement were 32.5% heavier. Analyses of fatty acid trophic markers suggested that juveniles preferentially fed on enriched rotifers rather than inert food. No pigmentation or fin erosion problems were observed in any of the weaning treatments, which indicates good rearing conditions.

Instar 1, 3, 5, and 7 phyllosomas of the spiny lobsterJasus verreauxi were reared individually at one of four temperatures (18, 21, 24, and 27C) and fed low, medium, or high rations of 2- to 3-mm Artemia salina. An increase in the temperature reduced the intermoult period for all instars tested, but only the instar 5 phyllosomas showed any significant differences in postmoult size with temperature; those at 18C were smaller. Phyllosomas reared at 18C ate fewer Artemia each day than did those at the higher temperatures, but instars 3 and 5 at 18C consumed more in total over the intermoult period. Survival for all instars tested was lowest at 18C. Increasing the food rations affected the growth and survival of instar 5 and 7 phyllosomas; those fed at the lower rations took longer to moult and had a smaller growth increment. For all instars tested, the feeding rate and total consumption increased with food ration.

Pratama et al, 2018. The Effect of Different C/N Ratio in for Biofloc of Formation Culture Media to the Growth and Survival Rate of Juvenile Climbing Perch (Anabas testudineus). JLSO 7(1): Climbing perch fish resources still have a problem due to this fish is still obtained only through capture and also the growth of climbing perch fish is slow. The solutions to increase the growth of the climbing perch fish is by applying biofloc technology for climbing perch fish culture. The purpose of this research was to know the effect of different C/N ratio on the growth of climbing perch fish (Anabas testudineus) juvenille with biofloc farming system. This research used a completely randomized design consist of four treatments and three replications. The treatments were without molase (P0), molase with C/N ratio 15 (P1), C/N 20 (P2) and C/N ratio 25 (P3). The results showed that C / N ratio 20 was the best treatment with absolute length of growth of 1.33 cm, absolute growth of weight 1.92 g, survival rate of 99.17% and feed efficiency 138.06%.

pH is one of the important water quality parameters in aquaculture. This study aimed to observe the growth performance and survival rate of common carp (Cyprinus carpio) Rajadanu strain reared in culture media with different pH levels. Fish (length: 3.60 ± 0.18 cm; weight: 1.68 ± 0.18 g) were stocked in nine aquariums (40 cm x 40 cm x 30 cm) for 10 days with a stocking density of 25 fish per aquarium. The treatments used were (A) pH 4-5, (B) pH 5-6, and (C) pH 6-7, with three replications. A commercial feed containing 28% protein was given daily and as much as 3% of the total biomass. The observed data were analyzed using variance analysis (ANOVA), followed by Duncan test. The results showed that the pH treatments did not affect the growth (length and weight) and survival rate of common carp Rajadanu strain (P>0.05). The best growth was achieved by the fish group reared in water with a pH range of 6-7 (length = 0.38 cm; weight = 0.17 g). The highest survival was attained by the fish group reared in water with a pH range of 5-6 (90.66%).

Abstract Folliculogenesis is a complex process that requires integration of autocrine, paracrine, and endocrine factors together with tightly regulated interactions between granulosa cells and oocytes for the growth and survival of healthy follicles. Culture of ovarian follicles is a powerful approach for investigating folliculogenesis and oogenesis in a tightly controlled environment. This method has not only enabled unprecedented insight into the fundamental biology of follicle development but also has far-reaching translational applications, including in fertility preservation for women whose ovarian follicles may be damaged by disease or its treatment or in wildlife conservation. Two- and three-dimensional follicle culture systems have been developed and are rapidly evolving. It is clear from a review of the literature on isolated follicle culture methods published over the past two decades (1980–2018) that protocols vary with respect to species examined, follicle isolation methods, culture techniques, culture media and nutrient and hormone supplementation, and experimental endpoints. Here we review the heterogeneity among these major variables of follicle culture protocols.
