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.

White-spotted spinefoot, Siganus canalicullatus (Park, 1797) is one of the most economically importantherbivorous fish captured along the coast of Selayar Islands. The present work was undertaken to assess thelength-weight relationship and Fulton's K condition factors of this fish caught in the waters of the northern coastof Selayar Islands District. Those parameters were calculated separately for both sexes. A total of 498specimens of S. canaliculatus consisting of 265 males and 233 females were randomly collected on a monthlybasis between January and June 2015 from local fishermen using gill nets of various mesh size in the coastalwaters of Desa Barat Lambongan, Kecamatan Bontomatene, northern part of Selayar Islands District. The fishwere brought to the laboratory and, after washing, their total length (L) was measured to the nearest 1 mm usinga fish measuring board and the total body weight (W) was recorded to the nearest 0.01 g using an electronicbalance. Each fish was then cut open and the sex were recorded. The length-weight relationships of males andfemales can be expressed as log W = –4.4220 + 2.7772 log L for males, indicated hypoallometric growthpattern; and log W = –4.6840 + 2.9022 log L for females, indicated isometric growth pattern. Overall, conditionfactor values were higher in males than in females.Keywords: condition factor, length-weight relationship, Selayar Islands District, Siganus canaliculatus, whitespottedspinefoot

The consequence of super intensive shrimp farming is an increase in aquaculture waste and disease transmission. Vibrio sp. Bacteria is a disease-causing agent in shrimp larvae when the shrimp is in a state of stress and weakness, and can cause death. The application of probiotics, namely beneficial microorganisms can degrade organic matter, reduce disease, and help accelerate the process of nutrient cycles as a consequence of super intensive shrimp farming. Commercial probiotics currently available are a mixture of several types of beneficial microorganisms, namely Bacillus sp., Pseudomonas sp., Nitrosomonas sp., Aerobacter sp., and Nitrobacter sp. The purpose of this study was to evaluate the use of probiotics with different time intervals to produce a decrease in the population of Vibrio sp. The research method applied was the treatment of commercial probiotics at different intervals of three, five, and seven days and without the administration of probiotics as controls. Furthermore, the bacterial population was calculated by total plate count (TPC). The results showed that the administration of probiotics had a significant effect on the decrease in the population of Vibrio sp. Provision of probiotics three days apart showed a decrease in the number of bacterial populations that were significantly different from the controls, but the same as the administration of intervals of five and seven days. The decrease in the number of bacterial populations in the treatment interval of three, five, and seven days in a row is 0.05 x , 0.41 x , and 0.61 x CFU / ml. This study recommends that the use of commercial probiotics intervals of seven days for super intensive vaname shrimp farming. The use of probiotics for three days indicates an impact on the increase in expenditure costs for probiotics. Commercial probiotic studies modified with natural microorganisms are thought to be able to streamline the operational costs of shrimp farming.Keywords: Vibrio sp. bacteria, probiotics, vaname shrimp, super intensive cultivation

Lamun merupakan tumbuhan tingkat tinggi yang hidup di laut dangkal. Sebagai tumbuhan, lamun berperansebagai produser primer yang memberikan kontribusi bagi biota laut maupun ekosistem lainnya. Hasil produksiprimer dari lamun akan masuk ke beberapa kompartemen. Namun berapa besar aliran produksi tersebut ke tiapkompartemen masih menjadi pertanyaan. Penelitian bertujuan untuk melihat berapa besar hasil produksi daunlamun yang dialirkan ke kompartemen lain. Penelitian dilakukan di Pulau Barranglompo Makassar selama 4periode yang mewaikili musim hujan, peralihan I, musim kemarau dan peralihan II. Penelitian dilakukanmelalui beberapa tahap, yaitu (1) mengestimasi produktivitas daun lamun, (2) mengestimasi stok karbon daunlamun, (3) mengestimasi besarnya grazing daun lamun oleh bulu babi dan herbivora lain, (4) mengestimasibesarnya produksi serasah daun lamun, baik yang tenggelam di dasar maupun yang terbawa keluar dariekosistem lamun. Hasil penelitian menujukkan total karbon yang dialirkan ke kompartemen lain mencapai2,20% dari stok karbon daun atau setara 81,8% dari produktivitas daun. Aliran produksi melalui serasah yangmelayang sebesar 0,59% dari stok karbon (setara 22,0% dari produktivitas daun), serasah tenggelam 1,36% daristok karbon (setara 50,6% dari produktivitas daun), grazing bulu babi 0,04% dari stok karbon (setara 1,4% dariproduktivitas daun) dan grazing oleh herbivora lain 0,21% dari stok karbon (setara 7,9% dari produktivitasdaun). Dalam konteks aliran produksi, hasil produksi primer lamun paling banyak berkontribusi dalam ekosistemlamun sendiri sebagai serasah, bisa dimanfaatkan oleh detritivore sebagai makanan, terdekomposisi sebagaiunsur hara, atau terkubur sebagai cadangan karbon. Hanya sebagian kecil produksi primer dimanfaatkan secaralangsung oleh herbivora.Kata kunci : produktivitas daun lamun, aliran produksi daun lamun, grazing lamun, serasah lamun

Refraction pattern of waves on the coast Sukamara have been known to conduct research in the year March –April 2014 . The prediction results showed that each season surge wave parameters that form there is adifference. This is because of differences in factors affecting pembangkitkan waves such as wind speed, duration,wind direction, and fetch. I transitional seasons wave direction most of the south and southeast (26.09 %) withheight and wave period at intervals ranging from 2.2 m - 3.1 m and 7.7 s - 8.7 s, the biggest wave of thesouthwest (3.8 m and 9.3 s). East monsoon waves are formed predominantly from the southeast (55.56 %),height and wave period at intervals ranging from 1.7 m - 2.7 m and 6.9 s - 8.1 s. The wave season is from thesouth east which is a storm surge of 3.5 m and 9.0 s. In the second transition back waves varies with thedirection of most of the southeast (26.92%) with height and wave period range in the interval from 1.9 to 3.1 mand 7.2 s - 8,5s. Due to refraction and shoaling pattern, so that the wave will experience changes in height,velocity and wavelength smaller than in the ocean waves. Deflection direction that causes the wave height of thewave decreases due to the speed and wavelength decreases. Convergence (penguncupan waves) generallyoccurs on the contour/coast which juts out (headland) and sund dune area, whereas divergence (spread waves)occur in the contour/coast that juts into the (bay area). Areas experiencing convergence generally cause abreaking wave height greater than the divergence area.Keywords: Sukamara coast, wind direction, wind speed, refraction, konvergen and divergen

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 .
