This research was conducted at Unit of business Freshwater Aquaculture (UPBAT) Pasuruan, East Java, on July â€“ September 2015. The purpose of this study was to determine the fish hatchery techniques of Cyprinus carpio in UPBAT Pasuruan. Hatchery goldfish in UPBAT include aircraft maintenance, preparation for spawning tub, parent selection, breeding, seed maintenance and feeding. Results obtained are spawning carp be done naturally by mass system, using the parent goldfish namely 4 female parent and 8 male parent of a total holding in UPBAT. In one spawning produced Â± 240,000 eggs, resulting in a year with three times the number of eggs obtained spawning Â± 720,000 eggs. The fertilized eggs will hatch 2-3 days after spawning, spawning once the larvae thus obtained Â± 236 128 Â± 708 384 larvae in a year so the HR = 98.38%. Once spawning is obtained approximately 205 984 fish seed so that in one year earned approximately 617 952 fish seed which means SR = 87.23%. Feeding the form of natural silk worms do after the yolk will run out (Â± 3-4 days) at a dose of feeding as many as 3% of the body weight of larvae / day approximately 100 grams, to 236 128 larvae. As for the mains feed pellets was given at a dose of feeding 3% of the parent body weight / day 2 kg for the mains and feed on the seeds with a dose feeding 3% of the seed weight / day to 800 grams to 205 984 fish seed.

The aims of this study was to determine the effect of the aquaponic system on the normalization of water quality for organic catfish cultivation, the survival rate of catfish and the growth of water spinach in the aquaponics system. The research method to be carried out is an experimental method using a completely randomized design (CRD) with different stocking densities, namely P1 (100 fish/m2), P2 (250 fish/m2), and P3 (500 fish/m2). The parameters measured were the water quality of the catfish culture media including NH3, NO2, NO3, pH, and dissolved oxygen, as well as the survival rate of catfish and kale plant growth (plant height, number of leaves, and leaf width). The results showed that rearing catfish with an aquaponic system with Kangkung plants could stabilize water quality. Value of water quality NH3 (0 – 0.1 ppm), NO2 (0 – 0.881 ppm), NO3 (0 – 1.443 ppm), pH (6 – 7.8), and dissolved oxygen (4.5 – 6.2 ppm). The survival rate was P1 (95.2%), P2 (94.3%), P3 (89.6%). The best growth of kale was found in the P3 treatment, namely plant height 37.2 cm, leaf width 2.5 cm, and number of leaves 24 strands. The results showed that the water quality was relatively stable. The higher the stocking rate, the lower the survival rate of catfish, on the other hand, the higher the stocking density, the better the growth of kale plants.

Natural feed has a very important role in supporting the success of aquaculture. The availability of natural feed is a key factor in the seed / fry phase, where at that phase the fish are still unable to consume additional feed, namely pellet feed. The objectives of this activity are: (1) Introducing Artemia, Improving the entrepreneurial spirit and entrepreneurial motivation, (3) Increasing the knowledge and abilities of SMK Ibrahimy 1 Sukorejo students in terms of decapsulation and artemia culture. This activity targets the fishery students of SMK Ibrahimy 1 Sukorejo, Department of Agribusiness, Brackishwater and Marine Fisheries. Service activities are carried out using lecture and demonstration/practice methods. Evaluation was carried out on the ability of participants to practice artemia decapsulation and artemia culture, indicators of the success of this practice are theoretical and practical knowledge of Artemia sp culture. The success of this activity can be seen from the very high enthusiasm of students and the increasing knowledge of students about the decapsulation of Artemia sp. The obstacle that is used as an evaluation in this activity is that several additional tools are still needed to maximize the decapsulation practice of Artemia sp.

Grouper production in Indonesia can be supported by hybridization technology which can produce grouper species with relatively faster growth and more resistance to disease. Cantang grouper is a type of grouper fish that was engineered by crossbreeding between female tiger grouper (Epinephelus fuscoguttatus) and male grouper Kertang (Epinephelus lanceolatus). The purpose of this study was to determine the stages and technology of nursery grouper Cantang which was carried out at BPBAP Situbondo. The method used in this research is the method of observation, participation, and interviews. The primary data needed in this study are data on infrastructure, data on the number and size of seeds, feed management, water quality management, and harvesting. The data is presented with a descriptive method by discussing the data that has been obtained compared to the theories that have developed at this time. The results of this study indicate that cantang grouper nursery activities start from tank preparation, water filling, seed selection and distribution, feed management, water quality, fish pest and disease control, grading, and harvesting of cantang grouper seeds. During the practice period, the seeds were spread from hatcheries with a stocking density of 3000 to 5000 individuals in one tank with a size of 4 x 2.5 x 1 m, or the equivalent of 300 to 500 individuals/m3. The distribution of seeds is carried out after the acclimatization process, namely the adaptation process before releasing the seeds. After the seeds are removed, the tub is given an antiseptic to prevent disease in the seeds. There are several factors that can affect the growth rate of seeds, namely water quality management and feeding. During the maintenance period, a flowing water system is used, so that the water used is continuously renewed. In the morning, the seeds are flushed and soaked using fresh water, with the aim of releasing mucus on the seeds so as to reduce the potential for disease outbreaks. Nursery grouper at BPBAP Situbondo can run optimally by paying attention to the stages of cultivation, especially in the feed management and water quality management.

In order to strengthen the economy of the community in Sumberejo Village and overcome the limited stock to supply catfish, it is necessary to form a community business, namely a catfish cultivator group. There were twelve potential community members were gathered to be taught and assisted in the process of establishing and managing a catfish cultivation business. The members of the community were taught technically how to cultivate catfish right through to the marketing process, then facilitated the formation of farmer groups together with the Situbondo district fisheries instructor and the Sumberejo Village Head until the "Santri Aquaculture Ibrahimy" farmer group was formed. Assistance is provided starting from the process of building a pond, preparing the pond, keeping fish and harvesting, to the marketing process. The results of economic benefits began to be seen in the first harvest cycle, there was a profit of IDR 2,400,000, with capital issued of IDR 7,000,000,-. With the existence of the Santri Aquaculture Ibrahimy farmer group, it can be achieved at least to overcome the shortage of daily consumptive stock of catfish and to strengthen the village economy by opening up employment opportunities for the people of Sumberejo Village.
