Abstract

Sponge is marine organism from porifera phylum which is a filter feeder (filtering food). Sponge can be degraded by high sediment suspended seawater, which causing a sponge body blockage, which will inhibit the growth of the sponge and even experienced death. This study aims to analyze the sponge coverage, sponge species identification and the relationship between sponge coverage and sedimentation rate. Underwater Photo Transect (UPT) was used in this study at three (3) depths i.e. 3 m, 6 m, and 10 m. The results showed that sponge coverage in high sedimentation rate is lower and there are 17 sponge species were found which were divided in to 14 family. In addition to sedimentation, water quality also greatly affects sponge coverage, such as currents, dissolved organic matter, salinity, and turbidity. One cause of sedimentation comes from the land, such as the transfer of land functions. Sponge's existence will continue to be threatened by physical and chemical pressure, and sedimentation if exploitation cannot be controlled.Keywords: sponge, sedimentation, water quality, land change

Abstract

Rabbitfish (Siganus canaliculatus) are found in seagrass beds so that they have the potential to be cultivated in the ecosystem. Cultivation activities require appropriate environmental / land requirements and support to be able to live and develop optimally. This study aims to analyze: (1) Suitability of rabbitfish cultivation land in seagrass ecosystem, (2) The carrying capacity of the land for rabbitfish cultivation in the seagrass ecosystem. This research was carried out in the coastal area of Barru Regency in March-April 2017. This study uses a method with the Remote Sensing Technology and Geographic Information Systems (GIS) approach. The types of data collected are oceanographic oceanic parameters consisting of physical factors (temperature, depth, current velocity, and turbidity), and chemical factors (salinity, pH and DO). The results of the study showed that the waters area was suitable ± 135.76 ha. Results estimation of the carrying capacity/capacity of the waters for rabbitfish cultivation with an area of about 81.46 ha or around 407,300 cultivation units or 5000 units / ha (assuming 1 unit of cultivation =      2 m2 (0,0002 ha).Keywords: land suitability, rabbitfish, carrying capacity

Abstract

Seagrass ecosystems in the coastal Labakkang Pangkep regency is the habitat of various types of shellfish which is the target of local fishermen catch. One of the many species of shellfish found in this coastal area is the mussel shell (Marcia hiantina L.). This study aims to determine the relationship between the length and weight of the long shell size of mussel shells (Marcia hiantina L.) in the coastal waters catchment of Labakkang. This research was conducted in catching area at three locations in coastal waters of Labakkang based on density of seagrass and population with sampling every month from August 2014 until July 2015 by using descriptive method that is random sampling by measuring the length of shell and weight of each shellfish. The results showed that the constant value (b) of mussel shell (Marcia hiantina L.) in all observation stations ranged from 2,44 to 2,63, meaning growth pattern including negative allometrik means shell length growth faster than body weight with coefficient of determination (R2) ranging from 0,88 to 0,91 means to have a high enough. The distribution of the size of the mussel (Marcia hiantina L.) is found on the smallest C  size station with the range 1,50 – 1,88 cm and the middle value of 1,69 cm and the largest with a range of 5,34 - 5,72 cm and the middle value of 5.53 cm.Keywords: Bakalang shell, Length weight, Coastal waters of Labakkang, Allometric negative

Abstract

This study aims to study the performance of phytoecdisteroids from mulberry leaves in molting stimulating of mangrove crabs. The research was carried out at the Research and Development Center for Aquaculture at the Faculty of Marine Sciences and Fisheries at Hasanuddin University, located in Bojo Village, Mallusetasi District, Barru Regency, South Sulawesi Province. Mangrove crabs (Scylla olivacea) weighing 45-55 g and carapace widths 60-65 mm were used as test animals. There were five doses of mulberry leaf extract applied through feed, namely: A) 1.1 mg / g feed, B) 1.9 mg / g feed, C) 2.7 mg / g feed, D) 3.5 mg / g feed. Crabs were kept individually in plastic boxes that are floated above the surface of the pond. During rearing, crabs are fed 3% dry fish per day which has been enriched with mulberry leaf extract. The parameters observed were ecdysteroid compounds contained in mulberry leaf extract, ecdysteroid content in hemolymph before and after application of mulberry leaf extract, and molting percentage. Identification of the ekdisteroid compounds contained in mulberry leaf extract was carried out using Thin Layer Chromatography (TLC) and Measurement of the content of ecdysteroids in crab hemolymh was carried out using Ultra Fast Liquid Chromatography (UFLC).  The results showed that the 3.5 mg dose of mulberry leaf extract / g feed gave the highest increase in ecdysteroid hemolymph, which was approximately 1760 ekdisteroid per mL hemolimph, while the dose of 1.1 mg / g feed only provided an increase of 100 ng ekdisteroid per mL hemolymph. The higher the dose of mulberry leaf extract in the feed, the higher the increase in the concentration of hemolymph ecdysteroids, but the high concentration of ecdystoid in the hemolymph does not guarantee molting.  The optimal dose of mulberry leaf extract in the feed stimulating molting was 2.4 mg / g of feed.Keywords: mulberry, phytoecdysteroid, molting, crab, aquaculture

Abstract

Capture fisheries business is one of the coastal community business activities in Mallusetasi District which focuses on fish production by carrying out fishing activities in the sea using trolling line and set longline fishing gear. This study aims to comparative analysis of income of trolling line and set longline fishing rods so it can be used as a reference in the selection of effective and efficient fishing gear at Mallusetasi District, Barru Regency. This study was conducted in November 2017-January 2019 at Mallusetasi District. The data were analyzed using income analysis. This research is quantitative by using a survey method through interviews with a sample of 39 respondents and a set longline fishing rod fisherman totaled 19 respondents, so that the total sample is 50 respondents and observations using purposive sampling technique.. The results showed that the trolling line income was Rp 5.825.923 per month, while the total longline fishing line income was Rp 4.738.040 per month. This shows that the income of troll line fishermen is higher than long line fishing fishermen.
