This research was conducted in August-September 2019 in three (3) subdistricts in Tanete Riattang Timur District, namely Waetuo, Panyula and Toro. The objectives of this study is to formulate priority management strategies for vaname shrimp ponds against the distribution of parasitic diseases. Data were collected by measuring water quality directly at each pond and interviewing shrimp farmers, Head of Marine and Fisheries Agency, fishery extension agents and lecturers of Marine and Fisheries Polytechnics of Bone in the field fish disease. Data were analyzed using both descriptive analysis and Process Hierarchy Analysis (AHP). The results showed that management of vaname shrimp ponds against parasitic diseases distribution was still lack of attention. Vaname shrimp pond management strategies against parasitic diseases distribution in the District of Tanete Riattang Timur, Bone regency, South Sulawesi was directed at the aspect of water quality. According to this study, the aspects to be improved were water quality management, education and experience of farmers, feed management, the use of SPF and SPR certified fries and biosecurity.
Tilapia (Oreochromis niloticus) including the Cichlidae family from Africa. Measuring 200 -400 grams and omnivorous, it can consume vegetable and animal feed. Palm oil waste has a highenough protein so that it can be used as a source of vegetable protein in fish feed. This study aims todetermine the effectiveness of palm oil waste feed on the survival rate, growth and feed conversion oftilapia. This study used a Completely Randomized Design (CRD) with the number of treatments 3namely A = Palm Oil Dregs (POD) plus fine bran, B = POD plus fish meal, C = POD plus soy flour;with 3 replications. The parameters observed were survival, growth and Feed Convertion Rate (FCR).Stocking density for each tilapia 10 individuals / container. The results showed the survival oftilapia in treatments A and B gave the same results (86.66%) and treatment C (80%). The results ofanalysis of variance showed that the treatment did not significantly affect the survival of tilapia. Thegrowth parameters, both in absolute growth and growth rates of tilapia during the study showed thatthe treatment had a significant effect on the growth of tilapia and the best treatment was treatment B,while treatments A and C were not significantly different. The FCR obtained was treatment A (1.27), B(1.18) and C (1.16). The results of variance analysis showed that the treatment had no significanteffect on the tilapia FCR.
This research aims to determine the role female farmers in development of rural aquaculture and the factors that influence the role of women farmers in rural aquaculture Development. This research was conducted in January to February 2020 in Bulukumba Regency. The t test analysis method was the comparative test. The results indicate that the Role of Women Farmers in the Development of Rural Aquaculture in Bulukumba Regency had a positive impact and the average income of the groups receiving assistance had increased incomes. The results of the calculation of multiple regression analysis show that the factors that influence the role of women farmers in the economic improvement was age, degree level, land area, and level of experience, while the nature of work and the number of dependents do not directly affect the increase in income of farmers in economic improvement activities.
This research was conducted in Juli-September 2019 in the Intensive Bone Pond SUPM Negeri Bone, Bone Regency. This study aims to: (1) Describe the condition of the study site for pond intercropping patterns; (2) Knowing the type and density of mangroves at the study site; (3) Assessing the role of mangroves as biofilter for the pollution of vaname shrimp pond cultivation. The method used in data collection is done by direct measurement to the field for water quality at the location of the pond, the type and density of mangroves determined by using transects. The results showed that the pond intercropping pattern used in the Bone State SUPM Pond was a model of an open trench pond. The type of mangrove that dominates the research location is Rhizopora mucronata and for vegetation density each station was different where in the tree category station 1 had a vegetation density of 0.48 ind / m², station II was 0.87 ind / m², station III was 1.06 ind / m². For the stake category 1 station has a vegetation density of 0.24 ind / m², station II is 0.08 ind / m², station III is 0.68 ind / m². For the seedling category station 1 has a vegetation density of 77 ind / m², station II is 32 ind / m², station III is 15 ind / m². Mangroves in the vicinity of SUPM Bone Bone can play a role as biofilter for the pollution of vaname shrimp aquaculture results with measurements of water quality before and after passing through mangroves decreased
An ectoparasitic infection is one of the causes of losses for the farmers of red tilapia (Oreochromis niloticus). This study was aimed to determine the types of parasites, the level of attack includes the prevalence, intensity and dominance of ectoparasites in red tilapia by adding fermented copra meal to the feed. The research was carried out at the Maros Fish Farming Center, South Sulawesi, while observing parasites in fish were carried out at the BRBAPPP Fish Pathology and Health Laboratory, Maros. The treatments were tested by addition of fermented copra meal as follows: (A) 0% control; (B) 15%; (C) 30% and (D) 45%. The experimental feed was applied to the fish once a day by satiation. The parameters observed were 1) identification of parasites; 2) prevalence rate; 3) attack intensity; 4) dominance and 5) water quality. A total of 30 tilapia from containers were taken to observe the fish organs included, ectoparasites were observed using a smear method on the target organ (gills, scales and fins and eyes), then examined microscopically. The ectoparasites were identified based on Kabata (1985), Grabda (1981) and Moller and Anders (1986). The result found two types of parasites namely Argulus sp. and Epistylis sp. The result of the prevalence of Argulus sp. of treatments A, B, and D were obtained (3.33%) and intensity (1 ind/fish) except that Treatment C was obtained prevalence and intensity (0%). While the highest prevalence rate of Vorticella sp. in A (Control) was 20% (frequent infections) while other treatments were still relatively low at 3.33% - 13.3% (sometimes infections) with intensity of attacks 0-1 ind / fish (low infection rate). The dominance value in all treatments ranged from 0.1 to 0.85%. The range of water quality of fish container were temperature 26.3-29.2 °C, pH 7.5-7.8, DO 5.8-6.4 ppm and ammonia 0.02-0.26 ppm. The value was within good range for Red Tilapia.
Muh. Aryan R Suci. Growth of Baronang Fish (Siganus canaliculatus) in Basic Net Cages in Different Seagrass Conditions on Lantang Peo Island, Takalar Regency. Lantang Peo Island which is one of the islands which is covered by several types of seagrass. Data collection was carried out from September to October 2016 at the Lantang Peo estuary. The first treatment is observation of density, cover and identification of seagrass. The second treatment is measuring water quality and the last one is measuring the weight and length of the baronang fish. Observation of seagrass species obtained Enhalus accoroides and Thalassia hempichii species. The total density of seagrass at Station I was 47 (teg / m2) 10.03% cover of seagrass, 70 (teg / m2) density of seagrass at Station II was 17.12% and the total density of seagrass at Station III was 90 (teg / m2) 18.13%. Observation of the absolute growth of baronang fish weight at station I of 1 gr. At station II the absolute weight growth of fish is 3 gr and at station III the absolute weight growth of fish is 5 gr. Observations of the absolute length increase of fish at Station I were 1 cm, the absolute length increase of fish at Station II was 2 cm and the absolute length increase of fish at Station III was 3 cm. This difference occurs due to the different density structure of the seagrass at each station.
