STUDI BIOEKOLOGI PERAIRAN SUNGAI BATU BATU DAN SUNGAI WALANAE UNTUK MENDUKUNG KEGIATAN BUDIDAYA DI DANAU TEMPE KAB.SOPPENG DAN WAJO PROP.SULAWESI SELATAN
Study aim was to determine bioecology aspect of Batu-Batu and Walanae River for supporting aquacultureacitivies at Tempe Lake. Batu-Batu and Walanae Rivers were 2 out of 8 river where affected water quality ofTempe Lake. Research was conducted for 7 months and sampling was conducted for 5 times. Physical waterquality parameters were measured in situ while chemical, primary productivity and nutrients parameterswere analysed at laboratorium. Results showed that range of temperature and pH were 30.5 – 31.7oC and7.49 – 7.90, respectively. Range of phytoplankton and zooplankton abundance account for 512 – 2220 cell/Land 40 – 140 ind/L, repectively. Consentration nitrate was range 0.0015 – 0.0452 mg/L, while consentrationphosphate was range of 0.015 – 0.1340 mg/L Chlorophyll a concentration was range 0.007 – 2.550 mg/Land primary productivity had range account for 0.10 – 0.89. Based on water quality parameter concludedthat Batu-Batu and Walanae River had a significant effect on abundance of phytoplankton and primaryproductivity. Phosphate and nitrate concentration significantly affected on growth of phytoplankton andzooplankton, so this could be supported for aquaculture activities.
 
IDENTIFIKASI BEBERAPA SPESIES RUMPUT LAUT YANG POTENSIAL DIBUDIDAYAKAN DI PERAIRAN SULAWESI SELATAN
Indonesia has a long costline dan have a high natural fisheries resources. One of natural resources from thecoast area is seaweed. Seaweed is export commudity from fisheries sector and Indonesia is one of the thirdmain producer for seaweed in the world. Seaweed species that have been cultured and utilized was onlyseveral species such as Glacillaria sp, Euchema cottoni and Geledium sp, on the other hand, Indonesia has ahigh diversity of seaweed. Based on LIPI data survey on 1998, it was found that 55 species of seaweed atIndonesian waters. Through this data, it showed that Indonesian water has a high potency for seaweedculture development. Aims of this study were to identify seaweed species that has a high potency to becultured at South Sulawesi’s waters and to analyse natural potency of several seaweed species that can becultured. Results study showed that diversity of seaweed species was varied within South Sulawesi’s waters.The highest number of species account for 30 species that found at Pangkep waters and the lowest number ofspecies was found at Bone waters account for 5 species. There were three class of seaweed that found fromlocations, such as Red, Brown and Green algae. The highest number of species from Red algae class wasfound from Bantaeng waters, furthermore the highest number of species from brown algae class was foundfrom Pangkep waters.Keywords : Seaweed, seaweed culture, South Sulawesi waters

NISBAH KELAMIN DAN UKURAN PERTAMA KALI MATANG GONAD IKAN LAYANG DELES (Decapterusmacrosoma BLEEKER, 1841) DI PERAIRAN TELUK BONE, SULAWESI SELATAN
This research was conducted to investigate the sex ratio and the first gonadal maturity size of mackerel fish(Decapterus macrosomas Bleeker 1841). Samples were taken from June to October 2013 in the sub-district ofPanyula, District of East Riattang, in Bone region. Sample analysis was conducted at the Fisheries biologylaboratory, Department of Fisheries, Hasanuddin University, Makassar. Sex ratio was analyzed by using chiquadrat-testwhereas the first gonadal maturity size was obtained from the first size of the third-gonadal-maturitystage. There were 782 fish collected with male to female ratio 1,02:1,00. Statistically, the sex ratio from Bone waterswas 1:1, in other words, it is still in a balance condition. The male fish reached gonadal maturity stage at the size of195 mm, whereas the female at 210 mm. Keywords: sex ratio, gonadal maturity size, Mackarel fish, Bone strait
Frekuensi Pemberian Pakan Buatan Berbasis Limbah Untuk Produksi Kepiting Bakau Cangkang Lunak
Feed eficiency is largely determined by its availability in suficient quantities and on timefeeding, s o it is necessary to study the frequency of feeding for the best production of soft shell crab. Four feeding frequency (1 time per day, 1 time per 2 days, 1 time per 3 days, and 1 time per 4 days) tested in this study. Feed with nutrient composition of 30.86% protein, 7.2% fat, nitrogen free extract (NFE) 48.89%, crude fiber 5.7% enriched with vitomolt 0.1041 5 mg/g of feed to the standard dose and 0.4166 mg vitomolt/g feed to high doses; or equal to 700 ng vitomolt/g crab. Test crabsof Scylla sp. reared in crabs box and placed in the pond. The results showed the frequency of feeding 1 time per 2 days resulted in the highest percentage of molting (66.67%) and the lowest percentage of moulting was found at 1 per 4 times a day of feeding (36.67%). Growth param eters such as weight and carapace width, and feed eficiency did not difer among all treatments. Thus, feeding in the soft shell crab for the maximum production can be done with a frequency of 1 time per 2 days
PENDUGAAN BEBERAPA PARAMETER DINAMIKA POPULASI IKAN LAYANG (Decapterus macrosoma, BLEEKER 1841) DI PERAIRAN TELUK BONE, SULAWESI SELATAN
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.
