Feed is the main source of nutrients to support vannamei shrimp growth. The high cost of feed in operational costs due to the high raw material price of fish meal, limited availability, while the demand is high. Therefore it is necessary to find alternative materials that are low in price, have a high enough protein content and abundant availability such as golden snail flour. The purpose of this study was to analyze the effect of different proportion of fish meal and mashed snail (Pomacea canaliculata) as the main feedstock for the growth of shrimp vannamei (Litopenaeus vannamei). The experimental design used in this study was Completely Randomized Design (RAL) consisting of 5 treatments, namely A (57.18% use of fish meal in feed), B (42.89% use of fish meal, 14.30% mashed flour), C (28.59% fish meal usage, 28.59% mashed snail), D (Use of 14.30% fish meal, 42.89% mashed snail), and E (Use 57.18% golden snail flours). This study shows that the addition of mashed snail flour in the feed can increase the growth of absolute weight, the daily weight of vannamei shrimp, and can decrease the value of FCR.

African catfish (Clarias gariepinus) is a commodity admired by both farmers and consumers. However, one obstacle in nursery process, namely the high mortality of fry due to cannibalism, especially in mass scale nursery system. One alternative that can be done to reduce the potential for cannibalism is through a hormonal approach, namely the application of estradiol-17? hormone. This study aimed to evaluate the effect of estradiol-17? hormone within batch spawning groups on level of cannibalism of african catfish fry. This study used a non factorial randomized block design with three levels of estradiol-17? hormone doses treatment, i.e., estradiol-17? hormone on feed of 0 mg/kg feed, estradiol-17? hormone of 30 mg/kg feed, estradiol-17? hormone of 60 mg/kg feed, on three batch spawning groups. African catfish seeds were reared in concrete tanks with density of 1,194 fish/m2 within two weeks. The results showed that dose of estradiol-17? hormone treat-ment was not able to reduce cannibalism, but in third batch spawning group sup-ported absolute weight of 0.32 g (P<0.05), and in second batch spawning group were reduced cannibalism potential parameter by 0.61%, and a survival rate of 70.04%. Key words : Batch Spawning, Cannibalism, Clarias gariepinus, Estradiol-17?

Length of time entering readiness early reproduction so that the relative fecundity and the low degree of fertilization and the degree of hatching in the goldfish hatchery are a challenge in the effort to provide goldfish seeds in quality and quantity. The effort was made by combining kroto and oocyte developer in the female goldfish. This experiment was carried out in September 2019-March 2020 at the Aquatic Productivity Laboratory of the Faculty of Agriculture, University of Lampung. The test fish used were 60 females 5-month-old brood stock, with an average weight of 14.69±3.69 g. This study used a completely randomized design using two factors, kroto (g / kg of fish) and oocyte developer (ml / kg of feed) with two levels each: K1O1 (0 + 0), K2O1 (30 + 0), K1O2 (0 + 0.5), and K2O2 (30 + 0.5) and 3 replications for each treatment. The results showed that factor K (kroto) and factor O (oocyte developer) had no effect on the relative fecundity of female goldfish during 8 weeks of maintenance. Meanwhile, the combination of kroto and oocyte developer affected the relative fecundity of the female goldfish at the 8th week of rearing, the degree of fertilization, and the degree of hatching

Utilization of ex-sand pit lakes for aquaculture is difficult due to low water quality and high concentrations of iron (Fe). Phytoremediation using aquatic plants has been proven to be effective in reducing Fe in waters. This study aims to determine the growth, feed conversion efficiency and survival rate of tilapia (Oreochromis niloticus) cultured with ex-sand mining water media with phytoremediation treatment. Phytoremediation treatment was carried out by Eichhornnia crassipes, Azolla pinnata, and Salvinia molesta. Fish culture experiments were carried out in plastic tarpaulin tanks for 40 days, with ad satiation feeding, three times a day using the commercial feed. The results showed that phytoremediation with aquatic plants had succeeded in reducing Fe to a level suitable for fish culture. Fish culture experiments showed an absolute length growth rate of 0.09-0.18 cm/day and an absolute weight growth rate of 0.11-0.16 g/day. The feed conversion ratio was 1.18-1.40 and the survival rate was 98.04-99.08%. The survival rate of tilapia is high, the feed conversion ratio is medium and growth is low. The high environmental temperature and the decrease in water quality due to the absence of water changes and aeration are suspected of causing the low growth of fish. Therefore, further research with water change and aeration experiments and the use of other species of fish is needed to follow up the results of this study.
