Abstract

The infectious of ectoparasites has a harmful impact to mangrove crabs. This study aimed to know ectoparasites that infected mangrove crabs and determine the prevalence of ectoparasites that attack mud crabs. 10 crabs / pond were randomly taken from two pounds. Identification of Crab was conducted in Laboratory of Water Resource Management, Faculty of Agriculture, University of Sumatera Utara. Parasite were observed in walking foot, swimming foot, claws, carapaks and gill of the crab. The result showed that 4 ectoparasites i.e Vorticella, Epistylis, Zoothamnium and Octolasmis were found from crabs of two ponds. Vorticella, Epistylis, and Octolasmis of Bagan Percut Ujung showed a relative high prevalence of 50%, while Octolasmis of Tangkahan Lagan Showed high Prevalence of 30%.Keywords: Ectoparasit, Mangrove Crab, Prevalence

Abstract

Mantis Shrimp (Oratosquilla gravieri) is one of the water resources that has highly economic potential but in the waters of the Sei Tuan has not been optimally utilized. The research of morphometrics and meristir were used for identification, growth model analysis, and management efforts for Mantis Shrimp resourse. The research was conducted in December 2017 in the seawaters of the Percut Sei Tuan. Catching of shrimp was conducted on 3 stations with a total sample of 90 shrimps. The length of Mantis Shrimp that caught during the study was 8.10 cm to 16.9 cm. Correlation between morphometric characters is very strong with correlation coefficient (r) ranged from 0.774 to 0.992. In Mantis Shrimp meristic was obtained 4 to 6 pieces of thorns on telson, 6 thorns on dactylus and 0 to 2 thorns on propodus. Mantis Shrimp growth pattern in Percut water was negative allometric with b value ranged from 2.212 to 2.326 (b <3).Keywords : Morphometrics, Meristics, Water Quality, Mantis Shrimp, Percut Sei Tuan

Abstract

Kecombrang have chemical content such as saponins, flavonoids, polyphenols, essential oils, and saponins which maypotencial as antimicroba. The purpose of this study was to determine the optimal concentration of kecombrang (Nicolaia speciosa) leaf extract to inhibit the growth of fish pathogenic fungi Saprolegnia sp. in gourami (Osphronemus gouramy). This research was conducted 3 months, from January to April 2017. Methanol, ethyl acetate and n - hexane were used as solvents for kecombrang leaf extraction. Assay on inhibitory of extract of kecombrang to Saprolegnia sp. used extract concentration of 0, 20, 40, and 60. Toxicity test (LC50) was conducted in gouramy at extract concentration of 1000, 100, 10, and 0 ppm. Water quality was observed icluding temperatute, DO, pH. The results showed that kecombrang leaf extract was reddish green, reddish brown, and yellowish green in color. Preliminary test of phytochemical compound of the extract showed that the extract contained saponins, tannins, and terpenes. The inhibitory test showed that ethyl acetate at concentration of 60% was able to inhibit up to 7.7 cm of the fungal growth. LC50 of methanol, ethylacetat, and n - hexane leaf extract was 25.4, 22.7, and 26.2 ppm, respectively. Temperature was 29 - 30 0C, DO was 7.0 - 7.2, and pH was 7.4 - 7.5 at the time of study.Keywords: inhibitory test, kecombrang, leaf extract, gouramy (Osphronemus gouramy), saponin, Saprolegnia sp.
