Abstract

Belo Laut Village has 3,337 ha of mangrove potential spread over three hamlet areas, namely Belo Laut, Tanjung Punai, and Sukal. On the muddy beaches around the mangroves, the community has developed extensive cultivation of blood clams (Anadara granusa). The existence of cultivation in mangrove areas also has the potential to affect the existence of mangroves in the area. For this reason, it is necessary to know the perception of shellfish cultivators on mangroves and the reality of the condition of mangroves in Belo Laut Village so as to provide an overview of the potential for mangrove destruction due to Blood Clam cultivation. Data were collected by interviewing shellfish farmers in Sukal and Tanjung Punai Hamlets. The production of blood clam cultivation has become a new source of economy in Belo Laut Village which is carried out by almost all family heads in Sukal and Tanjung Punai Hamlets. The community considers that the mangroves in Belo Laut village had not changed in quantity and there was no indication of their use other than for tourism. The perception and understanding of shellfish farmers not to disturb the mangroves were based on the protection of their main source of income as shrimp and crab fishermen.

Abstract

The one of Belitung Island’s native fish which has important economic value is Cempedik fish (Osteochilus spilurus). Its consumption, which still relies on natural catchments, requires a study of its biology and ecology. One of the studies that have never been studied in the maturity of this species is the relationship of fecundity with fish weight - length and gonad weight. This study used samples of Cempedik fish from the Lenggang River, East Belitung which were obtained randomly from the catches of fishermen. Sampling adjusts the fishing season that occurs in the rainy season. The preparation was carried out on whole fish using 4% formalin. Calculation of fecundity gravimetrically and compared with fish lengths and gonad weights in the graph. Fecundity in 2015 was 222 – 10,947 eggs and in 2016 there were 335 – 2,060 eggs. Fish body length and weight affected the fecundity of the 2015 fish sample but had no effect on the 2016 sample. This is predicted to occur due to differences in sampling time to position and rainfall in the rainy season, availability and suitability of natural feed, and changes in habitat quality. Gonadal weight correlated with fecundity, where the higher the gonadal weight, the higher the fecundity. Keywords: Cempedik, rainy season, maturity, fecundity.

Abstract

Tilapia (Oreochromis sp.) is a consumption fish inhabiting freshwater and likeability by society. Tilapia’s benefits can attract breeders to cultivate in mass-producing with very high market demand. Every mistake that occurs in aquaculture activities is usually the feeding management which can cause various problems, such as damage to water quality that can trigger growth—diseases, including Motile Aeromonas Septicemia (MAS) caused by Aeromonas hydrophila. The use of Canbat assumed there are contain some antioxidants that can be used as immunostimulators to increase the survival of tilapia. This research aimed to find out the concentration of Canbat product PT. Meddia herbal is effective for the treatment of tilapia (Oreochromis sp.) infected by Aeromonas hydrophila bacteria. The method used in this research was experimental. The size of tilapia used is 10-11 cm with a density of 10 fish/container. The treatment doses used were P1 (40 ppm), P2 (60 ppm), P3 (80 ppm), Positive control (Amoxicillin), and Negative control (0 ppm), with 2-hour immersion. The parameters observed were clinical symptoms, fish survival, fish response to feed, and absolute weight growth. The results indicated that herbal Canbat with concentration (80 ppm) was effective in treating tilapia infected with Aeromonas hydrophila bacteria; it produces the fastest recovery of clinical symptoms on the 12th day and the highest survival rate of 90%.
