Abstract

This study aims to assess the condition of the coral reef ecosystem in East Biak waters and formulate a strategy for optimal and sustainable management of coral reef ecosystems in the waters of East Biak, Biak Numfor Regency. Data and information were collected through the application of various methods, namely field surveys using transect techniques, interviews using questionnaires and document tracing. The data analysis method consisted of analyzing the condition of the coral reef ecosystem, SWOT analysis. The results showed that the waters of East Biak had very varied coral reef ecosystem conditions with a range of 22 - 85% with an average percentage of coral cover of 68.78% and when compared to the percentage of coral cover in 2018 there was an increase of 12%, although found in some location has decreased. In the management of coral reef ecosystems in this area there is support from the government, but due to budget constraints, the management has not been carried out optimally. From the analysis, several management alternatives are recommended, namely; (1) Optimizing coral reef management through; zoning arrangements for coastal and marine areas, increasing community, private and government participation in coral reef management and strengthening regional regulations; (2) Conservation and rehabilitation of coral reef ecosystems through; strengthening regional marine conservation areas, carrying out conservation and rehabilitation of coral reef ecosystems, regulating fish utilization activities in the area, integrated law enforcement and strengthening community-based monitoring and supervision systems; and (3) Increasing the quality of life of the community through; public awareness of the importance of coral reefs, community empowerment, repositioning of community livelihoods and developing technology for the utilization of marine biological resources that are effective and environmentally friendly.

Abstract

Congo Tetra fish is one of the freshwater ornamental fish species which is in great demand because of its high economic value. Male congo tetra fish have a higher selling value than female fish, because the morphology of their bodies looks more attractive, especially their brighter colors and long fins. Sex reversal technology is one technique that can be used to obtain male monosexual offspring.The hormone 17α-methyltestosterone in male fish can increase spermatogenesis and determine secondary sex markers in male fish through the formation of sexual characteristics in fish morphology and body color. The administration of the hormone 17α-methyltestosterone with the right dose can increase the percentage of male sex of Congo Tetra fish. The purpose of this study was to determine the effect of the hormone 17α-methyltestosterone with different doses on the percentage of male sex, absolute weight growth, and survival of congo tetra fish, to determine which 17α-methyltestosterone hormone dose had the best effect on the percentage of male sex, growth in absolute weight, and survival in congo tetra fish. This research was conducted at the Regional Technical Service Unit of the Fish Seed Center for Ternate City. The time for conducting the research starts from March to May, 2020. In this study, 4 treatment doses of hormones were used, each treatment was repeated 3 times. The treatments tried were as follows: Treatment A: Dose 2 mg/l, Treatment B: Dose 3 mg/l, Treatment C: Dose 4 mg/l, Treatment D: Dose 0 mg/l (control).The results showed that the hormone 17α-methyl testosterone with different doses had a very significant effect on the male sex percentage of congo tetra fish, but it was not significantly different on the growth in absolute weight and survival of congo tetra fish. The highest average percentage of male sex in congo tetra fish was found in treatment C (dose 4 mg/l) which was 86.6%, the highest average value of growth in absolute weight was found in treatment A (hormone dose 2 mg/l) of 1.083 g, and the highest survival was found in treatment D (control) of 90.473%.

Abstract

Catfish has various advantages, including fast growth, high adaptability to the environment, delicious taste, and high nutritional content.  As a source of nutrition for reared fish, feed is a factor that plays a very important and decisive role in the success of fish farming.  The research aims to determine the effect of feeding frequency on the growth and survival of sangkuriang catfish larvae (C. gariepinus). The study was conducted from June to July 2020 at the Abelisawa Fish Seed Center (BBI), Sampara District, Konawe Regency, South East Sulawesi Province using a Completely Randomized Design with three frequencies of feeding treatment, namely treatment A feeding twice a day, treatment B feeding 3 times a day and treatment C feeding 4 times a day with 3 replications.  Data were analyzed using Analysis of Variance (ANOVA) at 95% confidence level (a 0,05).  The results obtained the highest daily growth in treatment B of 3.11 ± 0.04% per day, followed by treatment A of 2.58 ± 0.05% per day and the lowest in treatment C of 2.53 ± 0.03% per day.  The highest absolute growth was obtained in the frequency of feeding 3 times a day at 37.27 ± 0.20 g per individual, followed by 2 times a day at 27.64 ± 0.40 g per individual and the lowest at feeding 4 times a day at 26.51 ± 0.92 g per individual. Survival in all 3 treatments reached 100%.  Analysis of variance (α 0.05) shows that different feeding frequencies significantly affect the daily growth rate (0.05>0.00) and absolute growth (0.05>0.00) sangkuriang catfish larvae (C. gariepinus).

Abstract

White-Spotted Rabbitfish (Siganus canaliculatus Park, 1797) are herbivorous fish that are associated with seagrass habitat and are widely distributed in mangrove and coral reef habitats. The waters of the Buntal  Island – Kotania Bau have an ecosystem of seagrass medows, mangroves and coral reefs, with the association of S. canaliculatus as one of the target catch of fishermen. The purpose was study to analyze the biological aspects of S. canaliculatus, including: sex ratio, size of first maturity, and fecundity. The research was conducted from October 2015 until January 2016 in the waters of Buntal Island, Kotania Bay. Fish samples were collected from fishermen's catch using bottom gill nets and Set net. Each fish sample was dissected for sex determination and gonad maturity level. The analysis is used to see the relationship between body length and weight and fecundity. The results showed that 167 fish and 149 female fish. The ratio of male and female was balanced, namely 52.85%: 47.15% or 1.1: 1 (X2count 4.13 <X2table 11.34). The size of first maturity of female is 14.98 cm (14.5 - 15.5 cm) smaller than the male 18.9 cm (18.8 - 19.1 cm). The high potential of S. canaliclulatus based on the Fecundity obtained was in the range of 524,000 - 1,286,359 eggs. There is a positive relationship between body length and fecundity, indicating that the value of Fecundity increases with body size. To support its sustainable use in the wild, it is necessary to regulate the size of S. canaliculatus that can be harvest at a body length of > 15 cm TL, to provide opportunities for spawning and support population growth before exploitation, thus supporting responsible and sustainable fisheries.
