Abstract

Tilapia (Oreochromis niloticus) seeds is one of the fishery products that is in great demand by the public. National tilapia production increases every year. Transporting seeds is what determines success in maintaining survival during the transportation process. However, the transportation process can cause the fish to become stressed and vulnerable to death. This problem can be prevented by stunning the fish first. Anesthesia is carried out with the aim of extending transportation time by suppressing the fish's metabolic activity. The organic ingredient that can be used as an anesthetic is clove oil. Clove oil contains eugenol which can be used as an anesthetic for fish. The aim of this activity is to see the effectiveness of clove oil as an anesthetic agent in closed system transportation of tilapia seeds. The method used was 135 animals/treatment using 3 treatments and 1 control. Doses K (0.0%), A (0.25%), B (0.30%), and C (0.35%) with 3 repetitions. The experimental results showed that the highest survival value was in A 0.25% (2.5ml/l) with 90%, while the lowest survival value was in the C treatment with a survival value of 57.50%. The longest fish fainting time was in the C treatment with the fish fainting time being 120.2 minutes, while in B the fish fainting time was 107.7 minutes. The best effective dose used as an anesthetic in the process of transporting tilapia fry measuring 5-7 cm is 0.25% (2.5ml/l).

Abstract

Thalassiosira sp. is a natural feed that has high nutritional content and supports the growth of Litopenaeus vannamei larvae. This research aims to determine cell density, peak population, daily growth rate, and water quality parameters on intermediate scale culture of Thalassiosira sp. with different salinities. This research was conducted at CV. Manunggal Rasa by applying 28 ppt, 30 ppt, and 32 ppt salinity with two repetition. The highest peak population was found in the 28 ppt salinity treatment with an average number of 40×104 cells/ml and the lowest population was in the 32 ppt salinity treatment with an average number of 35.5×104 cells/ml. The daily growth rate reached the highest level in the treatment with 28 ppt salinity with a value of 0.28 cells/ml/day. Meanwhile, the 32 ppt salinity treatment had the lowest daily growth rate 0.14 cells/ml/day. The population peak occurred on the third day, after which there was a decrease in the number of Thalassiosira sp. cell populations. The results of this research indicate that the higher the salinity will reduce the results of the parameters tested.

Abstract

Tilapia (Oreochromis niloticus) is one of the freshwater fishery commodities that is popular with the public and has high economic value, and has other advantages, namely that it is easy to cultivate and can adapt easily to various environmental conditions in fresh, brackish and marine waters. Tilapia is a euryhaline fish, where tilapia has good physiological adaptation to a wide range of salinity and has the ability to equalize salt levels in both sea and fresh water. Areas that have brackish saline waters are usually used as pond land with shrimp cultivation or milkfish cultivation as the main commodity. This research aims to determine the optimal salinity regarding the survival and growth of red tilapia in various salinities that are maintained for 30 days in order to increase the potential for greater production by utilizing less productive pond land to meet domestic and international market demand for tilapia. which is increasing. The use of rearing media with a salinity of 19 ppt produces a survival rate of 87.3 ± 0.98%, and produces an average final weight of 8.07 ± 0.02 grams with an average initial weight of 2.08 ± 0.02 grams. The final daily weight growth rate was 0.258 ± 0.0007 grams/day. The average final length is 11.67 ± 0.04 cm with an average initial length of 3,25 ± 0.21cm. Final daily length growth rate 0.351 ± 0 cm/day. SGR 4.14 ± 0.03%. And the lowest FCR with a salinity of 16 ppt was 1.23 ± 0.02. Based on experiments conducted, using a salinity of 19 ppt in the rearing media could increase the survival and growth rates of red tilapia.

Abstract

Red tilapia (Oreochromis sp.) is the result of a cross between tilapia O. mozambicus and fish. tilapia O. niloticus. The advantages of tilapia are its relatively fast growth and relatively easy maintenance, as well as having a significant tolerance to environmental conditions. The growth rate of male fish is higher than that of females. Hormonal stimulants for male sexual orientation can be derived from natural ingredients, namely propolis. Propolis has advantages, including being safe for consumption, relatively inexpensive, and environmentally friendly. Treatment of propolis through immersion and artificial feed on red tilapia (Oreochromis sp.) seeds at a dose of 0.1 ml/L and 2.7 ml/kg of feed resulted in a male sex percentage of 85%, SR 100%, FCR treatment A (1 .43) and treatment B (1.34).

Abstract

The availability of broodstock in vannamei shrimp cultivation, especially in hatchery activities, is generally the main requirement. The lack of availability of good quality broodstock is an obstacle in shrimp hatchery activities. One of them is a decrease in egg hatchability which can affect the number and quality of Nauplius produced. Maturation is the initial stage in the process of prospective parent vannamei shrimp becoming mature gonads. Apart from that, the aim of maturation is to maximize growth into adult parent shrimp so that prospective parent vannamei shrimp are ready for spawning. Data collection through observation, documentation, and direct participation in the field in parent maturation activities. The average fecundity produced by each parent during the research ranged from 150-250 thousand eggs. Meanwhile the Hatching Rate was 78.60-79.91%, in December it was 68.37-72.71%. Fertilization Rate (FR) 60-75, Survival of vannamei shrimp in November 91.5%. December 89.5%. The results of water quality measurements, the temperature in the broodstock maturation rearing tank at PT Bibit Unggul Kalianda is around 28-30 oC and the salinity is around 30 ppt.

Abstract

The Marble Molly fish (Poecilia sphenops) and the Sunkist Balloon Molly (Poecilia sphenops) are one of the fish that are popular in Indonesia. It is hoped that crossing sunkist mollies and marble mollies will produce unique colors and new patterns, with diverse and unique colors so that public interest will once again be high in keeping ornamental fish, especially mollies. The methods used start from preparing tools and materials, preparing spawning tanks and larval rearing tanks, selecting mature gonad male and female parents with the characteristics of the male having a gonopodium on his stomach while the female does not have it with the age of the male and female being at least 4 months before they can be spawned. The cross is carried out with a ratio of males and females, namely 5 males and 10 females in each spawning tank, there are 6 spawning tanks with 3 tanks representing the cross between a marbled male and a Sunkis female and another 3 tanks with a Sunkist male and a marbled female, then the best data is taken from the 2nd following treatment. The results obtained were the emergence of 3 color variations and 5 pattern variations with unique and varied colors and patterns.
