Abstract

This study aimed to evaluate financial analysis of fingerling production of tiger grouper (Epinephelus fuscoguttatus) fed commercial pellet and trash fish. The experiment was carried out in floating net cages located in the Gondol Research Institute for Mariculture Bali. A total of 3,000 humpback grouper juveniles with the average body weight of 12 g and 8 cm of total length, were stocked in six 2x2x2 m cages at stocking densities of 500 fishes/cage. The cages were divided in two groups for two treatments in triplicates. The treatments were feeding with commercial pellet and copper raw trash fish. Results showed that  body weight gain, total length, specific growth rate, were not significant different (P>0.05) between fish fed commercial pellet and trash fish. Feed conversion ratios obtained by commercial pellet and trash fish were 1.43 and 4.53, respectively. Survival rates were significant different (P<0.05) between fish fed commercial pellet and trash fish which were 83.33 and 69.86%, respectively. Nursering for production of tiger grouper fingerling fed either commercial pellet or trash fish in floating net cage were economically feasible. Feeding with commercial pellet gave a higher net profit of Rp 4,486,250.- with the RC ratio of 1.47 and rentability of 47.12%, while feeding with trash fish gave a net profit of Rp 3,212,500.- with the RC ratio of 1.37 and rentability of  37.35%.This study aimed to evaluate financial analysis of fingerling production of tiger grouper (Epinephelus fuscoguttatus) fed commercial pellet and trash fish.

This research also aims to find out an applicable technology of shrimp aquaculture for fish farmers in the coastal area of Special Region of Yogyakarta. The basic method used in this research is descriptive research with research instrument in the form of a questionnaire. The descriptive research aims to provide a picture of a society, a particular group of people or a picture of a symptom. Data collection techniques are conducted by interviews and structured observation to obtain a more detailed picture of a phenomenon. The location of the research is determined by purposive sampling, focusing on Sidorejo, Banaran, Galur, Kulon Progo, Kuwaru and Ngentak, Poncosari, Srandakan, Bantul. The reason for taking 3 areas is because as the center of production of shrimp vaname first and the longest operates in the coastal area ofSpecial Region of Yogyakarta. Respondents were determined by proportionate random sampling from 3 specified areas. This research took place from June 18, 2015, to July 12, 2015. The results showed the application of the good fish farming method on the activity of enlargement of shrimp vaname (L. vannamei) on the coast of Special Region of Yogyakarta covers 10 parameters. These ten parameters include site selection; determination of construction layout and design; selection of cultivation containers; biosecurity; selection of fish seed (shrimp); use of fish feed (shrimp); use of probiotics; use of disinfectants; harvesting method and harvesting equipment. Application of good fish farming method at vaname shrimp (L. vannamei) aquaculture development in the coast of Yogyakarta Special Region averaged at 62.24%. Factors that influence the application of good fish farming in the shrimp aquaculture development activities are the existence of communication and socialization services on the technical methods for the shrimp aquaculture by employees of feed and probiotics companies. Counseling (communication and socialization), verification (recording) and control in the form of certification has not been done by the Department of Marine and Fisheries of Indonesia. The technology of vaname shrimp farming (L. vannamei) applied by farmers in the coast of Yogyakarta Special Region is semi-intensive technology.

Abstract

The aim of this research was to find out the effect of waste collection in red tilapia culture using floating net cage to the quantity of the waste and degradation rate, on survival and growth rate of fish. A completely randomized design was performed in the experiment consist of two waste collections; namely: with and without collection, and three fish stocking weights of 2.5 kg, 5 kg and 7.5 kg fish/cage, with two replicates each. Floating net cages with the size of wide, length and height of 1 x 1 x 1.2 m were used in the experiment. To collect fish waste, inverted cone-shape plastic collector was attached to the cage and hanged 15 cm below the cage. Fingerling size ranged from 50 – 70 gram/fish were divided into two groups and stocked in the different replication. The fish were cultured for 84 days and fed daily with commercial feed (25-27% protein content) at the rate of 3% fish body weight. Waste sample were collected and incubated in different temperature of 20, 25 and 30 oC with deviation of 1 oC and 3 replicate each. Parameter of total dissolved solid (TDS), total suspended solid (TSS), DO, BOD, CO2 and NH3 were checked every 5 days for 20 days, and total N and total P were check at the beginning and the end. Data were analyzed statistically using confidence level of 95%. Total waste collected were ranged 0.109-0.117 kg dry weight/cage and waste lossing due to fixing collector 15 cm under the cage was about 14.44%. The addition of waste collection in fish culture tended to make lower survival and growth rate, meanwhile more stocking weight may increase fish harvest. Fish waste decomposed faster in higher temperature, indicate that the waste decomposition could decrease water quality and increase concentration of N and P nutrients.
