his research was conducted in November to December 2012 which aimed to estimate thepopulation dynamic of mackerel fish through their age-group, growth, mortality, and yield perrecruitment. Samples were taken from the waters of sub district of Panyula, in the district of EastTanete Riatang, in Bone Region. Age-group was measured using Bhattacharya method with thehelp of Fish Stock Assessment Tools II (FISAT II) software. Growth and natural mortality weremeasured by applying the equations of Von Bertalanffy and Empiris Pauly (respectively). Whereastotal mortality as well as yield per recruitment were estimated by applying Beverton and Holdequation; and catch mortality was estimated by applying the equation of Z=F+M. Results showedthe average total length of 849 mackarel fish that was 121-295 mm. They were divided into 4groups with 306.35 mm asymptotic length, 0,33 growth rate coefficient and theoritical age of 0.0294year. Natural mortality rate, total and catch mortality, and exploitation rate were 0.3672per year; 2,4358 per year, 2,0687 per year and 0.8493 (respectively). This indicated that an overcatch had occurred due to the higher catch mortality compared to the natural mortality as well asthe yield per recruitment, i.e. 0.0865 gram/recruitment.

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

Saline tilapia fish is a result of technology engineering technique that is tolerant with brackish waters and sea with salinity ≥ 20 ppt. The main problem in the development of saline tilapia is the availability of seeds because the resulting synthesis is still low. One effort to overcome the problem of low tilapia salinity this is by providing dissolved organic material such as glucose. Glucose plays an important role as a source of energy for animals including tilapia. The aim of this research is to determine the optimum dose of dissolved glucose to the survival and growth of salt tilapia larvae (Oreochromis niloticus). The research was conducted from March to May 2017 at Brackish Water Aquaculture (BPBAP) Takalar, South Sulawesi. The research container using 25 L plastic volume basin amounted to 15 pieces. The test animals used were 7-day saline tilapia larvae of 0.03 gram sized for 20 days. The glucose used is pure glucose in powder form. The study was designed using a complete randomized design consisting of 5 treatments and each having 3 replications. The five treatments are 0, 50, 100, 150, 200 ppm per day added to the once-daily research container that is the morning. The result of variance analysis showed that soluble glucose administration had significant effect (p <0.01) on the synthesis and growth rate of saline tilapia fish. The highest survival rates and growth rates were achieved at 100 ppm doses of 94.44% and 14.93% / day respectively, while the lowest at doses of 0 ppm were 74.81% and 11.85% / day respectively.Keywords: glucose, salin tilapia, survival, growth rate

This research aimed to study correlation between the weight length and the condition factor of Pirikfish.The sample collection conducted from September 2014 through February 2015 in Sanrego river, LangiVillage, Bone regency, South Sulawesi. The analysis of the samples carried out in the Laboratory of FishBiology, Department of Fisheries, Hasanuddin University, Makassar. The total length was measured usingdigital calliper of 0.01 mm and the weight was measured using the digital scale of 0.001 g. The fish sampleswere dissected and categorized into male and females with the sex gonad maturity. The total samples of theendemic pirik fish collected during the research were 162, 72 male dan 90 female fish. The correlation of theweight length was based on the equation W=0,00003L2,8719 at male fish, W=0,00003L2,8575 in the female fish andin general, the obtained equation was W=0,00003L2,8846. The result of the t test showed that the value washigher than t table; therefore, the Pirik fish in Sanrego rivers had negative allometric growth attern (minor) (b <3), since the addition of body length was faster than the increase of body weight. The analysis of the conditionfactor revelead that the value range of 0,8038-1,2926 with an average 1,0274 in male fish and 0,9263-1,4533with the average of 1,1598 in female fish. This showed that the conditions factors of the endemic pirik fish werelower compared to the female fish.Keywords : Length weight, condition factor, endemic-pirik fish, Sanrego River, South Sulawesi
