Ikan pepija merupakan ikan demersal dengan penyebaran di perairan estuaria dan laut dangkal. Penelitian ini bertujuan untuk mengkaji distribusi spasial dan temporal ikan pepija di perairan P. Tarakan. Penelitian dilakukan dari Februari 2013 sampai dengan Februari 2014. Penangkapan ikan dilakukan dengan menggunakan pukat hela (trawl) dengan ukuran panjang sayap 7 meter dengan besar mata jaring pada sayap, badan dan kantong masing-masing berukuran 2,2 dan 1 inch. Pengoperasian jaring trawl pada masing-masing lokasi stasiun dilakukan âzig zagâ dengan 2 kali masa penarikan pukat hela (towing) selama 30 menit. Ikan yang tertangkap ditimbang seluruhnya. Hasil tangkapan bervariasi saat waktu pengamatan dan antara satu stasiun dengan stasiun lainnya. Laju tangkap tertinggi pada bulan Desember dan Januari sebesar 75.56 dan 77.37 kg/jam dan terendah pada bulan April sebesar 7.41 kg/jam. Ikan pepija melakukan migrasi harian dari Tanjung Simaya (tanggal 7 kalender Hijriah), tanggal 8 di perairan Tanjung Selayu, tanggal 9 antara perairan Tanjung Selayu dan Tanjung Juata, dan tanggal 10 pada penanggalan Hijriah di perairan Tanjung Juata. Berdasarkan data tangkapan tersebut terungkap bahwa distribusi ikan pepija di perairan Pulau Tarakan berkaitan dengan pasang surut, ikan ini hanya ditemukan pada saat pasang perbani pada tanggal 7, 8, 9 dan 10 bulan Hijriah.

ABSTRACTStudy of Reproduction Aspects of Endemic Fish Bonti-bonti (Paratherina striata)in Lake Towuti, South Sulawesi. Bonti-bonti, is one of endemic fishes in Lake Towuti andLake Mahalona. Bonti-bonti has been utilized by people around the lake for consumption inthe form of 6esh fish, dry fish, and salty fish; as ornamental fish; and as raw material foranimal feed. It should be protected from decreasing of fish population due to increasingexploitation and habitat quality changes. The objective of this research is to know thereproduction aspects of this endemic fish, as basic data for conservation. This research wasconducted in Lake Towuti, South Sulawesi from May 2006 to April 2007 at five stations.Samples were collected using experimental gillnet sized 0.625, 0.75, 1.0, and 1.25 inches.The result shows that testis and ovary was found each in one organ during a period of gonadadevelopment. Gonada maturity, was observed histologically oscured at five maturity stages.The range of egg diameters were from 0.01 to 1.50 mm. The fust gonada maturity period ofmale and female fish were reached at 5.53 and 6.26 cm of total length, respectively. Male andfemale fish gonada maturity (50%) were at 16.78 and 14.61 cm total length, respectively.Gonada maturity index value of male and female were 0.01-3.96% and 0.02-6.77%. Thereproduction ability is related to fecundity which have an effect on number ofjuveniles. Therange of fish fecundity were 818-6,051, which were devided kom female with 11.30-18.33cm total length. Bonti-bonti fish is partial spawner type.Key words : Reproduction aspects, endemic fish, Paratherina striata, and Lake Towuti

Study on habitat, distribution and size structure of opudi (Telmatherina antoniae) was carried out in Lake Matano, South Sulawesi from September 2010 to August 2011. Habitat was described based on underwater observations. Fish collections were accomplished monthly by using beach seine. The fish was distributed throughout littoral areas within clear water. The observed habitat ranged between sandy, cobbles to bouldery bottom substrate. Some parts of habitat had less vegetation and the others did not. Fish collected during the study were 2707 individuals, in which 53.08% of them were males and the remains were females. The individuals had standard length (SL) ranged between 32.76 and 85.67 mm. Male specimens were dominated by individuals ranged between 41.58 and 54.80 mm (78.98% of total male specimens). Female specimens were dominated by individuals ranged between 37.17 and 54.80 (87.80% of total female specimens). Both male and female individuals were dominated by large size classes.Key words: Distribution,habitat, size structure, Telmatherina antoniae.

The Lubuk Lampam floodplain’s ecosystem is naturally affected by the fluctuation of the water surface. This ecosystem also receives anthropogenic substances such as nutrients and other chemicals, especially from the oil palm plantation and its industrial processing activities. The main objective of this research was to determine the trophic status of the floodplain using the trophic level index (TLI) and Carlson’s trophic state index (TSI). The water quality and the fish samples were collected and analyzed from 7 stations representing various types of floodplain habitat. The results showed that the trophic status of Lubuk Lampam was hypereutrophic (very nutrient-rich). This was also supported by the high increase of the body weight (“b” value more than 3) and the high gonadosomatic index (GSI) of the studied fishes, i.e. Osteochilus vittatus 2.53-6.81% (male) and 3.00-15.86% (female); Helostoma temminckii 0.28-3.33% (male) and 1.30-10.43% (female); and Channa striata 0.33-0.59% (male) and 0.21-2.73% (female).
