Tinfoil barb, Barbonymus schwanenfeldii (Bleeker, 1854), is a potential freshwater fish for Indonesian aquaculture. Before widely used, the candidate needs to be evaluated. This research aimed to evaluate the reproductive performance of the first generation (G1) and larval performance of the second generation (G2) of domesticated tinfoil barb. A total of 68 female and 24 male broodstocks were selected for the artificial breeding program. The gonadal maturity test was carried out by canulating the eggs every month. Before spawning, GnRHa hormone was injected into the dorsal area (0.5 mL/kg for female and 0.2 mL/kg for male). Fecundity, fertility rate, hatching rate, embryogenesis, and larvae ontogeny were recorded. The results showed that the first matured G1 males of tinfoil barb were at the standard length of 16.01 ± 1.18 cm, while females at 15.79 ± 1.23 cm. The mature broodstock indicated by the gonad maturity stage III and IV confirming higher estradiol concentration (above 400 pg mL-1). The fecundity of two mature broodstock-sized of 217.2 g and 197.3 g were 12,495 and 15,782 eggs, respectively. The spawning season of G1 tinfoil barb was in October and November (rainy seasons). The fertilized eggs latency time was 10 hours 44 minutes at 25°C and hatched after 23 hours 7 minutes. The fertility rate was 96.96 % and the hatching rate was 95.16 %. The survival rate of G2 normal larvae was 100 % at three days of the rearing period. The G2 larvae production in this experiment provides an excellent opportunity for fish diversification both for aquaculture and restocking.

Humpback grouper Cromileptes altivelis is seawater that lives in tropical waters, especially in Indonesia. This fish has high economic value and is the most expensive grouper fish in Indonesia. Humpback grouper seeds can be used as ornamental fish or raised for consumption fish. This study aimed to evaluate the growth performance of humpback grouper cultivated with the cage system. During the maintenance, fish were fed with 1-5% feed ratio. Fish were reared from 30g to 200g in size, and a feed conversion ratio of 2 was obtained with a survival rate of 94%. The fish were started to be given mixed feed with a 3-4% feed ratio, consisting of 15% pellets and 85% fresh fish which had been cut according to the fish mouth opening. The next maintenance starts from fish measuring 200g to reaching 500g with a survival rate of 93%. The profit obtained from harvesting 12 times in one year is IDR 590 587 187 years-1, R/C Ratio 1.80, the payback period is 1.7 years, break event point IDR 376 100 576, BEP unit 895kg, and price cost of production (HPP) Rp 233 312kg-1.

Sembilang Fish (Plotosus canius) is one of the fish found in estuarine waters, and it's quite popular with the community. Excessive fishing by the community causes the habitat of sembilang fish to be threatened to decrease. The purpose of this study was to determine the water quality and examine the environmental conditions of sembilang fish in the dry season and rainy season in the estuary waters of Langsa City as the basis for domestication. This study used a descriptive method by collecting water quality data at 3 research stations and collecting fish data that was taken from fishermen's catches in Langsa estuary waters. The results showed that the water quality parameters observed in the dry season and rainy season in the estuary were still in decent condition for the life and existence of sembilang fish. Season greatly affects the body weight of both male and female fish. In the dry season, the female weight ranges from 120–220 g and the male 120–240 g, while in the rainy season, the female weight ranges from 134-572 g and the male 136–260 g.

Clownfish Amphiprion sp., have a relatively wide distribution area, especially in Indo-Pacific waters. In nature these fish live in small groups in one anemone and consist of one pair of parents, the others are usually smaller in size which are still in the male sex. If one of the parent pairs dies, the position will be replaced by the largest in the group, especially the female. This condition is usually called sequential hermaphrodite. The purpose of this study was to gather information on the techniques for fish hatchery clownfish to produce quality fish. Clownfish spawn with a sex ratio of 1:1, with an average spawning frequency of 2 times a month. Clown fish can produce eggs with an average of 419 eggs, fertilization rate (FR) 76,37%, hatching rate (HR) 75,27%, and survival rate (SR) 58,35%. For one year, the total number of fish hatchery that can be produced is 108.911. Payback period of 8,2 years, break event point (unit) of 73.859 fish/year, break event point (rupiah) of Rp. 369.292.918, and cost of production of Rp. 3.817/fish

Pacific whiteleg shrimp is a cultivated commodity with the prospect of increasing market opportunities yearly. The increase in value is in line with the increasing need for pacific whiteleg shrimp consumption. The impact is an increase in state income in general. Pacific whiteleg shrimp cultivation activities have been carried out on a large and small scale. However, proper enlargement production techniques are needed to increase production. This study aims to determine the technique of pacific whiteleg grow-out so that the information obtained can be disseminated to the public and will add value to the benefits of improving welfare. A study case method with a descriptive analysis approach was used. Pacific whiteleg shrimp culture is divided into the hatchery and grow-out sectors. The grow-out activities include pond cleaning, media preparation, fry stocking, feeding, treatment, pest and disease management, growth sampling, and harvesting. Based on the study's results, the production consisted of three cycles per year with a density of 180 m2 an SR value of 85.5%, and an FCR value of 1.25%.

The development of mirror carp (Cyprinus carpio) farming in Indonesia has progressed very rapidly, as can be seen by the increasing number of varieties of mirror carp produced from various regions with their respective specifications and advantages. Along with the need for carp that are more resistant to environmental changes and disease attacks, the development of the Majalaya carp variety subsequently produces Mantap carp fish that are disease-resistant, and growth in the growth segment is faster. The aim of this study was to disseminate technical information on Mantap fish carp culture to the public so that it can be used as a reference source for the community, especially for cultivators who are interested in developing this fish. In this study, primary and secondary data were collected. Based on the results of a fecundity study, one female broodstock produced 104.496 kg broodstock-1, the average percentage of egg fertilization (FR) was 89,64%, the average hatching rate (HR) was 61,37%, and the average survival rate (SR) until the size of the seed size 2-3 cm reaches 60%.
