Abstract
The Bio-Transplants method is a coral grafting method by inoculating coral seedlings/fragments using natural materials. They are dead corals in the DC and DCA categories as a place of attachment. This study aims to see the success of the Bio-Transplants method in compiling indicators of fish species associated with the field of Bio-Transplants. They have conducted this research in 10 x 10 square meters on the north side of Tunda Island waters in July 2019 (T0), November 2019 (T1), and July 2020 (T2). The sampling method used a stationary visual census. In July 2019, as many as 11 species from 7 families, November 2019 was 31 species from 10 families, and July 2020 was 47 species from 10 families. Composition of fish species as an indicator of the health of coral ecosystems from the Chaetodontidae family fish species. In July, when Bio-Transplants started production, there were no fish groups from the Chaetodontidae family. The composition of the fish species found in November was Chelmon sp. and Henichus varius. After its age, the Bio Transplants area was one year (July 2020) consisting of 4 fish species from the family Chaetodontidae, namely: Heniochus chrysostomus, Chaetodon trifasciatus, Chelmon sp., and Heniochus varius.
Highlights
The presence of reef fish, both in quantity and quality, is closely related to the health status of coral reefs, as evidenced by the percentage of living coral cover according to [1]
Based on various descriptions of previous research results, this study aims to determine the success rate of coral habitats rehabilitation using the Bio-Transplants method with indicators of the presence of reef fish species based on their function
The fish species found before the tests were Thalassoma amblycephalum and Thalassoma lunare from the family Labridae
Summary
The presence of reef fish, both in quantity and quality, is closely related to the health status of coral reefs, as evidenced by the percentage of living coral cover according to [1]. It is the type of diversity in the coral reef ecosystem. Reef rehabilitation is a part of fisheries technology innovation that focuses on coral restoration or repair to coral reef ecosystem stability. Took the development of the rehabilitation model from the concept of [4], namely by collecting corals directly from the reef and transplanting them into damaged areas. The product in question will make a model with stratification to see the difference in growth
