Abstract

Raja Ampat Islands have been designated as a Marine Nature Reserve (SAP) since 2014, and community activity in these waters remains high for tourism, fishing and sea transportation activities. All of these activities have the potential to suppress the condition of the coral reefs there. Therefore, it is necessary to evaluate the effectiveness of zoning in terms of social and ecological indicators. This research was conducted using the Underwater Visual Census (UVC) method for coral reef fish and the Underwater Photo Transect (UPT) method for coral cover at a depth of 5-7 m. The set critical threshold value is used to evaluate the success of the zoning taken by interviewing fishermen. The results of the study found that the core zone had unfavorable conditions compared to the other zones. Based on an analysis of ecological indicators, the percentage of coral cover was only 20.9% and an abundance of reef fish of 28 ind/m2. The results of the social analysis of the community, Waisilip Village has the lowest level of compliance with a value of 56%. Meanwhile, 77% of respondents agree with zoning, and only 19% understand the zoning management system. The management of SAP Raja Ampat can be said to be effective by taking into the ecological and social indicators of the community. Increase in the percentage of coral cover in the core zone (0.2%), utilization zone (3.9%), sustainable fisheries zone (0.8%) and cultivation zone (5.7%). Most fishermen have good insight and concern for coral reefs and other aquatic resources.

Abstract

The The waters of Raja Ampat have a healthy coral reef ecosystem and a wide variety of species so it has a high abundance of coral reef fish. One of the indicators of fertility level in water is chlorophyll-a and its high and low are influenced by sea surface temperature. The purpose of this study was to determine the relationship between chlorophyll-a content and sea surface temperature using satellite imagery data on the community structure of reef fish in the waters of SAP Raja Ampat. The coral reef fish data collection method used UVC (Underwater Visual Census) while the chlorophyll-a content and sea surface temperature used spatial analysis. The results showed that the reef fish diversity index value was 4,1 - 4,6 in the high category, uniformity 0,88-0,96 in the high category, dominance 0,014 - 0,026 in the low category, for abundance 244.340 ind/ha – 403.520 ind/ha and biomass 131,45 kg/ha - 204 kg/ha. The chlorophyll-a content obtained was 0,366 mg/m3 – 0,511 mg/m3 and the sea surface temperature obtained was 30,717°C – 31,899°C. The results of the relationship of reef fish community structure with chlorophyll-a content and sea surface temperature do not have a significant correlation.

Abstract

Vanname shrimp cultivation is one of the most developed aquacultures in Indonesia and makes it one of the commodities with the highest foreign exchange inputs for the Indonesian state from the fisheries sector. Disease attack is one of the main causes of failure in vaname shrimp culture, especially disease attacks caused by Vibrio parahaemolyticus bacteria. Avicennia alba mangrove leaf extract is known to have active compounds that can act as antibacterial. This research was conducted by mixing Avicennia alba mangrove leaf extract with doses of 150 ppm (VA), 250 ppm (VB) and 350 ppm (VC) into commercial feed by re-pelletting. Positive control (KV+) treatment used commercial vitamins added to the feed. The vaname shrimp used was 60 days old with an average initial weight of 8.9 grams. The aquariums used were 15 pieces with a size of 60 x 30 x 40 cm and a volume of 54 liters of water. The white shrimp challenge test with Vibrio parahaemolyticus bacteria with a concentration of 106 Cfu/ml as much as 0.2 ml. The clinical symptoms of white vaname shrimp include pale white hepatopancreas, blackened tail, grippy swimming legs, necrosis in some parts of the body, necrosis of the tail, blackened and necrotic rectum, broken intestines that are partially brown and starting to turn white, empty intestines, presence of white feces. appears in the aquarium, decreased appetite, as well as not actively swimming. The results showed that Avicennia alba leaf extract had an effect on absolute weight growth (W), growth rate (GR), specific growth rate (SGR), survival rate (SR), total haemocyte count (THC) and phagocytic activity of white shrimp. The dose of 350 ppm VC treatment was the most influential dose as an immunostimulant in this study.
