Abstract

Male tilapia is preferred by cultivators because it has a higher growth speed or matures quickly (sexual maturity) than female tilapia. Efforts need to be made to increase the production of tilapia by applying masculinization to increase the production of male tilapia. Masculinization activities can be carried out using the hormone 17α-Methyltestoteron. However, the use of these hormones usually leaves a carcinogenic residue which not only does not meet food safety requirements but also endangers consumers. Efforts to masculinize can be done by immersing the larvae in a water solution of honey. Honey contains chrysin which acts as an aromatase inhibitor resulting in increased hormone production and male traits become dominant. The purpose of this activity is to determine the male sex ratio from immersing tilapia larvae in honey solution. The larvae used were 7 days old, then soaking was carried out for 20 hours using honey with a concentration of 15 ml/L capable of producing 76% male seeds.

Abstract

Vannamei shrimp is a prospective commodity that continues to be cultured intensively in Indonesia. Efforts to produce vannamei shrimp fry are an activity that continues to be developed by stakeholders, including efforts to improve genetics. Apart from a good aquaculture system, genetics is also an important factor in the success of vannamei shrimp culture. This research was conducted at CV. Manunggal Rasa with a research design carried out using a comparison of 2 genetics of vannamei shrimp larvae, namely American Penaeid, Inc (API) and Benchmark Genetics (BM) with a stocking density used of 40,000 individuals/m2 in each pond with an area of 25 m2. Rearing vannamei shrimp fry for 4 cycles provided several differences in the observation of absolute length growth and survival rate. The absolute length growth of the API genetic vannamei shrimp fry was 5.68 mm, while the BM genetics was 6.16 mm. The survival rate in each cycle is cycle 1 (API 89.9% and BM 93.1%), cycle 2 (API 91.4% and BM 95.6%), cycle 3 (API 88.9% and BM 89 .7%) and cycle 4 (API 93.2% and BM 94.6%). The water quality for each cycle is calculated to be optimal, namely ranging from 27-31oC (temperature), 4.5-5 ppm (DO), 30 ppt (salinity), 0-0.1 ppm (ammonia) and 7.9-8.3 (pH).

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.
