Abstract

Transplantation of coral reefs requires sufficient fragments but must still ensure the sustainability of coral donors. This research aimed to know the survival rate and growth rate of transplant corals with different fragment sizes and planting positions and to determine the most effective and efficient transplantation methods of the Seriatopora hystrix. The research was conducted from January to April 2016 in Serangan Island waters Denpasar Bali (1-2 m depth). The method used was a field experiment with variations of planting position (vertical, horizontal) and fragment sizes (3, 5, 7 cm). The results showed a high survival rate (98.3%) of the transplanted S. hystrix with planting position and fragment sizes variation. The variation of planting position and fragment sizes were significantly affected the length growth rate of the S. hystrix (p <0.05). The vertical planting position showed better growth compared to the horizontal planting position. The transplantation of coral with initial fragment sizes of 5 and 7 cm showed a higher growth rate than the fragment size of 3 cm. However, statistical analysis revealed no significant difference between initial fragment sizes of 5 and 7 cm. Therefore, this study demonstrated the most effective and efficient for S. hystrix transplantation showed in the vertical position with the initial fragment size of 5 cm.Key words: coral bleaching, initial fragment, tropical, zooxanthellae

Abstract

Acanthocephala is a parasite commonly found in the digestive tract of fish. This study aimed to determine the prevalence and mean intensity of Acanthocephala infecting the shortfin scad (Decapterus macrosoma) caught from the southern coast of Yogyakarta and to identify those parasites by morphological approach. A total of 221 samples of fish were obtained from local fishermen operating in fishing grounds along the southern coast of the Indian Ocean in the Special Region of Yogyakarta. The fish samples were measured for total length (TL) and weight and dissected to examine for the presence of Acanthocephala. Parasite samples were collected from the digestive tract of shortfin scad and preserved in absolute ethanol for further identification. Data analysis focused on calculating prevalence and mean intensity of infection. The results showed that the prevalence of Acanthocephala infection was 16.3%, with a mean intensity of 1.9 larvae/host. Both the prevalence and the mean intensity tended to increase with increasing fish length. Most of the shortfin scad (75%) was infected with Acanthocephala at a relatively low intensity (1-2 larvae/host). The highest intensity of Acanthocephala infection was 13 larvae/host and was only found in one fish. Morphological identification indicated that the genus infecting shortfin scad was Acanthocephalus (Koelreuther, 1771). Keywords: Acanthocephalus, biological tag, morphology, parasite, prevalence
