Abstract

Information on the biometric characteristics, egg morphology, and habitat of O. javanicus are very important for its use as model fish in the laboratory, ornamental fish, and environmental bioindicators. Therefore, research is needed to analyze the biometric character, egg morphology, and habitat of ricefish O. javanicus in the brackish water pond of Banten Bay. This research was conducted non-eperimentally by observing biometric characters to examine meristic, morphometric, and sex dimorphism characteristics. Observations of egg morphology were macroscopic and microscopic characteristics. Habitat characteristics were observed by measuring water quality in situ. The results showed that O. javanicus from Linduk had meristic characteristics D.6–7; A.21–22; P.9-10; V.5–6 and sex dimorphism in the shape and size of the dorsal and anal fins. Blue metallic color pattern on the head and yellow color on the fins are potentially ornamental fish. O. javanicus eggs have a diameter of 1.08 ± 0.02 mm, are equipped with attaching filaments and non-attaching. The non-attaching filaments are 0.14 ± 0.03 mm in length. The percentage of yolk area was 73.7 ± 4.85%, and the oil droplet area was 8.3 ± 0.54% of O. javanicus at the gastrula stage with egg yolk volume 0.349 ± 0.048 mm3. Water quality in this study is a reference for rearing O. javanicus in the laboratory.

Abstract

Coral rehabilitation on Tunda Island is carried out to support marine tourism, which is the mainstay of the community tourism sector. Because of this, the Student Creativity Program (PKM) is being carried out, namely community service (PM) related to fishdom-based coral transplants. This activity is the creation of artificial coral reefs that aim to restore underwater ecosystems, fish populations and diversity. The program's success starts from selecting locations and community participation through community knowledge. Based on this, the activity objectives were to obtain information on community knowledge about coral and marine ecotourism, recommendations for implementing coral transplants, and the location of PKM-PM on Tunda Island. The stages of the activity are planning, data collection in the community, and data analysis. Coordination is carried out with the local government and tourism awareness groups (Pokdarwis). The data was collected through non-formal interviews with community representatives in 2 RW 6 RT in Wargasara Village, Tunda Island. The interviews showed that more than 50% of the people of Tunda Island had good knowledge about coral reefs and their functions, coral transplants, the condition of coral reefs, fish locations and ecotourism on Tunda Island. More than 60% of the people of Tunda Island do not know the structure of the fishdom and have never attended socialization and training on coral transplantation. Therefore, the community suggests conducting coral transplantation training and fishdom construction on Tunda Island is necessary. The community suggested that coral transplants could be carried out in East Tanjungan and fishdom placement on the North Beach to support underwater tourism on Tunda Island. Community involvement, especially Pokdarwis, can guarantee the sustainability of PKM-PM activities on Tunda Island through coral conservation education-based tours.
