Abstract

Existence of parrotfish in Bali, especially at Kedonganan fish market, Badung Regency are already familiar for local society and visitors. However, the research about parrotfish specifically about parasites is still scarce. One factor that cause the decrease of fish quality is diseases caused by the presence of parasites in the fish body. This study aims to determine the various types of ectoparasite, abundance, prevalence, relationship between length or weight and number of parasites in the parrotfish (Family Scaridae). The sample of research were collected from Kedonganan fish market, Badung Regency, Bali from November until Desember 2019. The research was used a descriptive methods with purposive sampling technique. Ectoparasites found in the 35 gills of parrotfish were Gnathia sp. (492 ind), Hatschekia sp. (156 ind), and Haliotrema sp. (1.186 ind). The highest ectoparasite abundance is Haliotrema sp. (33.88 ind/fish) while the highest ectoparasite prevalence was Gnathia sp. (80.00%) and belong to a “usually” of infection level. The correlation between the length and number of parasites is in the “medium” level with the value of correlation (r) was 0,460 while the correlation between the weight and number of parasites was in the “medium” level with the value (r) was 0.502.

Abstract

Ornamental fish, both freshwater and seawater fish, are commodities that are in great demand by the community and have a great opportunity to be developed. Pigmentation in ornamental fish has an important role in the brightness of fish colour. Clown fish (Amphiprion ocellaris) is one of the ornamental fishes that requires carotenoids as a source of nutrition in the formation of body colour. The purpose of this research is to investigated the effect of different colour of culture containers on the quality improvement of the clown fish body colour and on the of growth and survival rate of cultured clown fish. The research method used was an experimental method. The size of clown fish used in this study were 4-5 cm and cultured in black, white, blue, and yellow containers. The results of this study showed that the colour of different maintenance containers has no effect on the total value of carotenoids found in skin or fish fins. However, visually the colour of different maintenance containers has an influence on each colour of the clown fish. The best value for total carotenoids was obtained using a white colour container. The growth rate at each treatment shows a difference in each week. Clown fish have the ability to live in bright and dark environmental conditions, therefore the treatment of different container colours does not affect the survival of clown fish.

Abstract

The Indian scad (Decapterus russeli) is a pelagic fish that has high economic value, found throughout the Indonesian waters. The availability of Indian scad resources makes this fish easy to find, especially in Kedonganan Beach, Bali. The use of Indian scad for human consumption makes it necessary to pay attention to the quality of indian scad in order to avoid fish diseases, such as parasites. The attack of endoparasites in Indian scad can be zoonotic, which can be dangerous for humans who consume them, so research is needed to determine the density of endoparasite attacks and the percentage of endoparasites in indian scad. Samples of Indian scad (D. russeli) were obtained randomly from PPI Kedonganan and Kedonganan Fish Market. The observed organs were intestines, gonads and liver. The research was conducted for 1 month from 16 December 2020 to 17 January 2021 and fish samples were taken by random sampling. There were 35 fish samples (D. russeli) examined. The endoparasites found were Anisakis sp. (316 individuals), Camallanus sp. (15 individuals), and Lecithocirium sp. (33 individuals). The highest intensity in the genus Anisakis was 9.2 ind/fish and was classified as moderate infection and the highest prevalence was also in the Anisakis genus, which was 97.14% with (almost always categories), 60% of the genus Lecithocirium (very frequent categories), and the Camallanus genus of 28.50% with (frequent category).

Abstract

This study aimed to find out the relationship between the maturity level of female abalone gonads with fecundity and egg diameter size of abalone. The results obtained showed that abalone having gonadal maturity level 1 was in the range of 3-4.5cm; gonadal maturity level 2 in the range size of 4.6-6 cm; and gonadal maturity level 3 in the size range> 6 cm. The results of the abalone gonad histology test showed that abalone with gonadal maturity level 1 had more ootid distribution than the primary oocyte. gonadal maturity level 2 has more ootid distribution, primary oocytes than secondary oocytes. Whereas in gonadal maturity level 3 it appears that secondary oocytes dominate which means the gonads are mature and ready to be spawned. The oocyte diameter is getting bigger and more similar simultaneously with an increasing level of gonad maturity. Abalone with gonadal maturity level 1 has an average oocyte diameter of 187 ?m gonadal maturity level 2 of 190 ?m, and gonadal maturity level 3 of 217 ?m.Abalone fecundity for gonadal maturity level 1 ranged from 60,480-86,190 oocytes; TKG 2 ranges from 196,560-214,520 oocyte grains; and TKG 3 ranges from 483,600-518,880 oocyte grains. Based on the results obtained, it can be concluded that the higher the level of maturity of the abalone gonad, the greater the fecundity with the distribution of more secondary oocytes seen in the results of the gonad abalone histology test.
