Abstract

Feed is one main factor in aquaculture activities which influences the quantity and quality of aquaculture commodities. Feed can also increase the cultivated fish survivability to prevent from fish diseases. Binahong leaf powder is one material added in the fish feed making which contains active compounds functioning as antibacterial agent. This study did aim at examining the influence of Binahong leaf powder addition to feed on the prevalence and survival rate of Red Tilapia seeds infected by Aeromonas hydrophila bacteria. This research employed an experimental method using a randomized complete design with four treatments. Each treatment consisted of different Binahong leaf powder dosage used as the material in feed making with treatment A (5%), treatment B (7%), treatment C (9%), and treatment D (control). The test animals were ± 5 cm red tilapia seeds infected by Aeromonas hydrophila bacteria. Feeding was given twice, in the morning and evening with the feeding rate of 10% per day of the total body weight. The research results showed that the addition of Binahong leaf powder did not influence the prevalence and survival rate of red tilapia seeds infected by Aeromonas hydrophila bacteria. Keywords: Aeromonas hydrophila, Bacteria, Binahong, Disease, Feed

Abstract

Mangrove crabs (Scylla sp.) are important economic fishery commodities that will be developed in Gorontalo Province. Mangrove crabs have large and prospective market opportunities in the domestic and foreign market. The mangrove crabs demand in this country is very high. Market demand for mangrove crabs has not been able to be fulfilled, because of the limited catch and the production of aquaculture which is still very minimal. The problem is how the development of mangrove crab cultivation will be applied in Gorontalo Province. The purpose of this research was to study and determine the development strategy of mangrove crab cultivation in Gorontalo Province in accordance with the potential and carrying capacity of the environment. The researched method was survey method with observational data collection and random sampling techniques. Data analysis was performed descriptively and SWOT analysis. Based on the SWOT analysis the strength (S) most influential on the development of mangrove crab culture in Gorontalo Province is government support and profitable business prospects (0.66), while the biggest weakness is the limited capital (0.54) and the low quality of human cultivation resources (0,48), and the biggest opportunity (O) is economic value (Very popular, because it is delicious and contains high nutritional value) (0.8), and threat (T) environmental degradation (0.8). Based on the quadrant of the analysis is in quadrant 1 (Growth Oriented Strategy). Keywords: Development, Strategy, Scylla spp, Cultivation, Gorontalo Province
