Abstract

Improper shrimp hatchery can have an impact on the low level of fry quality so that fry production results also decrease. Therefore, quality vannamei shrimp hatcheries must be handled appropriately in accordance with standard operating procedures that have been implemented so that they are marketable. So it is necessary to study more deeply about the vannamei shrimp hatchery, especially the vannamei shrimp hatchery technique. The purpose of this study is to find out a number of things including: Operational Standards for Vanname Shrimp Hatchery; Gonad maturity performance; and Post-harvest activities of vanname shrimp hatchery. The shrimp hatchery technique uses analysis by calculating the Fertilization Rate (HR) and Hatching Rate (HR). Based on the results of the study it was found that: 1). The technical aspects of the CV Manunggal 23 shrimp hatchery in general are in accordance with the standard procedures referred to. 2). The broodstock productivity performance at CV Manunggal 23 has a good rate with an average HR of 75.83% and FR of 62% within 3 weeks. 3). Water Quality in CV. Manunggal 23 achieved optimal numbers with an average temperature of 27-28°C, pH 8, DO 5.5-5.6 mg/L, and Salinity 32-33 ppt within 3 weeks.

Abstract

To achieve success in the maintenance of cantang grouper requires mastery of techniques in good hatchery of cantang grouper (Epinephelus fuscoguttatus >< Epinephelus lanceolatus) in order to produce optimal productivity both in terms of quantity and quality. The aims of this study were: 1) To find out the development and growth rates in cantang grouper hatcheries (Epinephelus fuscoguttatus – lanceolatus), 2) To determine the condition of water quality in cantang grouper hatcheries (Epinephelus fuscoguttaus – lanceolatus), and 3) To determine the feasibility of cantang grouper hatcheries (Epinephelus fuscoguttaus – lanceolatus). The data analyzed in this study include data on growth, water quality, and business analysis. The results of the analysis showed that: 1) In a day the average length increase reached 0.074 cm and the percentage rate of increase in length of cantang grouper larvae for 29 days from the age of D30 – D58 was 7.4%. At the beginning of measuring the length of cantang grouper larvae, the average length was 1.12 cm and at the end of the observation the average value was 3.28 cm. 2) From the results of water quality maintenance, the temperature ranged from 29 – 31°C, oxygen dissolved 4.37 – 4.87 mg/L., pH 7.4 – 7.9, and salinity 28 – 30 ppt, 3) In terms of financial or business feasibility the cantang grouper hatchery activity at the Blitok BPBAP Situbondo Installation can be said to be feasible to do and profitable with a net profit of Rp. 665,904,233/year with an R/C ratio of 3.7. Break Event Point (BEP) price of Rp. 111,539,155/year with production BEP reaching 37,179 heads. Payback Period (PP) for 1 year.
