Eco-biological information of Cheilopogon abei in Geser Streit is unknown. The objective of this research is to observe the sex ratio, first size maturity, gonad maturity and gonado somatic index (GSI) with fecundity of flying fish Ch abei in Geser East Seram Strait waters. Sampling was done for ten months started from February to November 2018, using gill net measuring 1.50 inch. All fish samples were measured in fork length and weighted so dissected to make observations on the level of gonad maturity and the number of eggs in female fish. A total of 682 flying fish was found during the study with a fork length range of 182.6-243.3 mm and a weight of 73.98-115.45 g. The results of the analysis showed that the proportion of the number of male fish was less than that of the female fish for almost every month of observation. The first size gonad mature of male and female is 210.5 mm and 214.1 mm FL. The gonad maturity index of male fish ranges from 0,963-7,967 and female fish ranges 1,315-8,069, the total fecundity is 2321-9438 eggs. Gonads of ripe fish in each month of observation. The spawning peak of Ch abei takes place in June-July and it is hoped that no arrests will be made in both months, to ensure the sustainability of the stock.

Perairan di sekitar Barru Sulawesi Selatan merupakan salah satu kawasan terumbu karang yang penting di Selat Makassar. Sebagian besar dari nelayannya melakukan penangkapan ikan dengan menggunakan rawai dasar dan jaring insang dasar. Analisis perikanan ikan kakap merah (Lutjanus spp.) dan kerapu (Epinephelus sp.) dilakukan pada bulan Agustus dan Oktober 2006 dengan penekanan pada deskripsi alat tangkap dan teknik penangkapannya, komposisi hasil tangkapan, dan beberapa aspek biologi ikan kakap merah dan kerapu. Penelitian ini dilakukan dengan cara mengikuti kegiatan nelayan yang menggunakan rawai dasar dan jaring insang dasar di sekitar terumbu karang dan pencatatan data dari pendaratan ikan utama. Untuk kelengkapan data dilakukan wawancara dengan nelayan dan pedagang pengumpul setempat. Hasil penelitian ini menunjukan daerah penyebaran ikan kakap merah dan kerapu terdapat di perairan Barru dan Pangkajene Kepulauan. Pada perairan yang relatif dangkal (<50 m) digunakan pancing ulur dengan satu atau dua mata pancing (nomor 6 atau 7). Jaring insang dasar digunakan di luar daerah karang, satu pis (tinting) mempunyai panjang 40 m dan dalam 5 m dengan ukuran mata jaring 4 inci. Satu unit jaring terdiri atas 60 pis. Di perairan yang lebih dalam (lebih dari 50) digunakan rawai dasar yang terdiri atas 600 mata pancing (nomor 7 atau 8). Lama trip penangkapan tiga hari. Diperoleh laju pancing pada rawai dasar berkisar 6-8% dan laju tangkap jaring insang dasar berkisar antara 40-60 kg/kapal/tiga hari. Komposisi hasil tangkapan didominansi (47,2%) oleh ikan kakap merah (famili Lutjanidae) yang terdiri atas jenis Lutjanus malabaricus, Lutjanus hyselopterus, Lutjanus sebae, Lutjanus vittus, dan Pinjalo pinjalo. Ikan kerapu (famili Serranidae) terdiri atas jenis Epinephelus areolatus, Epinephelus malabaricus, Epinephelus microdon, dan Plectropomus maculatus. Kecuali itu tertangkap juga ikan lencam (famili Lethrinidae). Pengamatan biologi jenis ikan Lutjanus malabaricus dan Epinephelus malabaricus yang merupakan hasil tangkapan dominan masing-masing diperoleh nilai modus panjang cagak 48 dan 56 cm dengan modus bobot masing-masing 1,8 dan 2,15 kg. Karakteristik pertumbuhan kedua jenis tersebut adalah allometrik positif.The sea waters around Barru, South Sulawesi is one of the coral reef parts in Makassar Strait. Most of the fishermen use fishing lines, bottom long lines, and bottom gill nets in their fishing activities. Analysis of red snappers (Lutjanus spp.) and groupers (Epinephelus sp.) fisheries in this area were carried out in August and October, 2006. The emphasis is focused on the discription of fishing gear and fishing technique, catch composition, and some of biological aspect of red snappers and groupers. The research was done by following the fishing operations of bottom long line and bottom gill net conducted by fishers in the waters around coral reefs. Data were recorded in some importantant landing place at Barru, and interview of some fishermen to complete data and information needed. The result showed that the distribution of red snapper and groupers occured in the waters around Barru and Pangkajene Islands. In the shallow waters (<50 m) the fishermen use a lightly weighted hand line, with one or two relativelly small hooks (nomor 6 or 7). Bottom gill nets are frequently used in shallow back reef areas with one piece of 40 m in length, and 5 m in depth, with mesh size of 4 inches. One unit of the gear consisted of 60 piece of the nets. Meanwhile, in deeper waters (50-150 m), the number of hooks (nomor 7 or 8) in bottom long line operated 600 hooks for each unit. All fishing gears usually have three days at sea for a fishing trip. The average of catch rate (hook rate) for a trip of bottom long line was 6-8% (6 or 8 individual fish for 100 hooks). Meanwhile, the catch rate of bottom jaring insang was about 40-60 kgs/boat/3 days trip. The catches were dominated by the family Lutjanidae in which the red snappers species (reached to 47.2% at this survey period) including Lutjanus malabaricus, Lutjanus hyselopterus, Lutjanus sebae, Lutjanus vittus, and Pinjalo pinjalo. Meanwhile the groupers (family Serranidae) were dominated by species of Epinephelus areolatus, Epinephelus malabaricus, Epinephelus microdon, and Plectropomus maculatus. Other groups were emperors (Lethrinidae) and Gymnocranius. The biological measured for Lutjanus malabaricus and Epinephelus malabaricus as a dominant landed showed the modus of length were 48 and 58 cmFL, respectivelly. Meanwhile the modus of weight were 1.8 and 2.35 kg. The growth characteristic of both species were positive allometric. It means that increasing the weight was faster than their length.

Marosatherina ladigesi is an endemic fish species in South Sulawesi and is famous as ornamental fish. However, the biological information of this species is still restricted. This research direct analyzes the length-weight relationships and condition factors of M. ladigesi. Sampling was held monthly from May 2018 to April 2019 in the Walanae Cenranae River Watershed, South Sulawesi. Fish samples were assembled by seine net. A total of 550 M. ladigesi were collected consisted of 227 fish in Camba River, 88 fish in Sanrego River, and 235 fish in Batu Puteh River. The length-weight relationship of male and female fish was W = 0,0002L2,74 and W = 0,00004L3,23 in Camba River, W = 0,0001L2,78 and W = 0,0001L2,92 in Sanrego River, W = 0,0001L2,88 and W = 0,00006L3,12 in Batu Puteh River, respectively. In Camba and Batu Puteh Rivers, the growth pattern of male and female fish were negative allometric and positive allometric, respectively. Conversely, the growth patterns of male and female fish in the Sanrego River were isometric. The condition factor fish in Sanrego River was lower than Camba and Batu Puteh River. These findings are valuable data for establishing a monitoring and conservation of this endemic species in its habitat.

Shark fisheries in Indonesia are still relying on the natural catch. Several shark species are important fisheries commo-dities and are highly collected. Although there are several rules to control catch, usage, and conservation status, in practice, fishermen are less submissive. This study was conducted to obtain information about species diversity, per-formance, and sex ratio of sharks which were found in Cilacap Port in October to November 2015. The method used was purposive random sampling technique. Samples were taken four times with two weeks interval for each observation. The parameters were species number, total body length, body weight, morphometry and sex. Data were analyzed descriptively. Thirty six sharks were recorded during the sampling which consisted of 14 species. Among 36 individuals, 7 individuals were juveniles, 3 individuals were adolescence, and 26 individuals were adults. Alopias superciliosus (321 cm) was the longest species, while the shortest was Sphyrna lewini (59 cm); Isurus oxyrinchus was the heaviest (100 kg) species and the lightest species was Carcharhinus falciformis (1 kg). In general, female fish were obtained more than the males. AbstrakProduksi ikan hiu di Indonesia masih mengandalkan hasil tangkapan dari alam.
