The objective of this research is to observe reproductive biology of Indian mackerel in Takalar coastal waters through gonad maturity development, the first size of mature gonad, spawning, gonado somatic index (GSI), and fecundity. Sampling was done for eight months started from March to October 2015. Gonad maturity stage was observed morphologically, spawning season focusing on direct observation result toward gonad by identifying Indian mackerel which has spawned.GSI was analyzed based on comparison between gonad weight and Indian mackerel weight while fecundity was observed by gravimetric method. Analysis result shows that Indian mackerel gonad maturity throughout the year with peak occurring in July and August. GSI was around 0,928-4,490. The first size of gonad mature of female Indian mackerel is 21,18 cm and male Indian mackerel is 21,31 cm. Spawning occurs after peak of gonad maturity so next month, value of maturity index decreases slowly and gradually. Indian mackerel has total fecundity around 11.235- 40.878 granule. AbstrakPenelitian ini bertujuan untuk mengamati biologi reproduksi ikan kembung lelaki di perairan pesisir Takalar melalui perkembangan kematangan gonad, ukuran pertama matang gonad, musim pemijahan, indeks kematangan gonad (IKG), dan fekunditas. Pengambilan sampel dilakukan selama delapan bulan mulai Maret sampai Oktober 2015. Perkembang-an kematangan gonad diamati secara morfologi. Musim pemijahan mengacu pada hasil pengamatan langsung terhadap gonad dengan mendata ikan kembung lelaki yang telah memijah. IKG dianalisis berdasarkan perbandingan antara bobot gonad dan bobot tubuh ikan kembung lelaki, sedangkan fekunditas dihitung dengan metode gravimetrik. Hasil analisis menunjukkan bahwa ikan kembung lelaki mengalami kematangan gonad sepanjang tahun dengan puncak terjadi pada bulan Juli dan Agustus. IKG berkisar 0,928-4,490. Ukuran ikan kembung lelaki betina kali pertama matang gonad adalah 21,18 cm dan jantan adalah 21,31 cm. Pemijahan terjadi setelah puncak kematangan gonad sehingga pada bulan berikutnya terjadi penurunan nilai indeks kematangan secara perlahan dan bertahap. Ikan kembung lelaki memiliki fekunditas total berkisar 11.235-40.878 butir.

<p>Indonesia is one country in the world exporters of tuna in the form of fresh, frozen and<br />processed. Tuna exported in processed form large enough to leave waste for exporting companies.<br />The purpose of this study was to determine a feasibility study on solid waste exported tuna loin for<br />raw material diversification. This research was conducted in Majene Makassar Strait. The study was<br />conducted using descriptive exploratory method by taking a sample of 3 times and each sample<br />was tested 3 times resulting in 9 times of testing for each of the observed variables. Chemical test<br />which includes moisture, protein, fat, ash, carbohydrates, and histamine. Microbiological test that<br />is E. coli, Salmonella and the total number of bacteria. Data were analyzed by descriptive qualitative<br />and quantitative display via Tables, Graphics and Image in the form of average value. The results<br />showed that the chemical solid waste tuna loin has a water content ranged from 78.34 to 78.78%,<br />protein content ranged from 14.32 to 16.41%, fat ranged from 1.56 to 1.66%, ash content ranged<br />from 5.18 to 5. 58%, carbohydrate content ranged from 1.29 to 1.34%, and histamine ranged from<br />2.08 to 3.21 mg / kg. Solid waste microbiologically tuna loin contains E.coli range from 1.2 to 1.9<br />(&lt;2), Salmonella negative and TPC ranged from 1.4 to 1.8 x 105 kol/g. The results of chemical and<br />microbiological testing showed solid waste tuna loin still suitable as raw material diversification<br />products.</p>

The objectives of the present study were to determine the size distribution, growth pattern, feeding habit and stomach fullness index of bullet tuna Auxis rochei in the Makassar Strait, West Sulawesi. The research was conducted for six months between March and August 2017. Sampling collection was carried out using the handline technique. A total of 2160 fish were caught. Their total length ranged from 15.8 to 28.5 cm and weight ranged from 52.3 to 366.5 g. The total length of male fish ranged from 18.5 to 28.5 cm and weight ranged from 77.5 to 366.5 g. The total length of female fish ranged from 15.8 to 27.5 cm and weight ranged from 52.3 to 328.8 g. The growth pattern of bullet tuna for both male and female fish was classified into a positive allometry (b>3); the type of food found in the fish gut consisted of crustacean (12.50% to 25.64%), chepalopods (7.32 to 34.80%) and unidentified (47.69 to 64.51%), respectively. Nonetheless, the predominant food condition was not identified and in the gut there was generally no food present. The stomach fullness index ranged from 1.13% to 7.18%, ¾ (12.11 to 15.74%), ½ (12.27 to 23.14%) and empty (59.26 to 65.74%). The length size distribution of male bullet tuna was larger than the female with a positive allometric growth pattern. However, the growth pattern of male and female bullet tuna statistically showed no difference.

In obtaining the data, the research is using survei method carried out for four months, starting April to July 2016 at Makassar strait. The data obtained was descriptively analyzed.  The research result presented that the number of fish caught at shallow FAD 568 fish (45.92%), consisted of skipjack tuna Katsuwonus pelamis (9.86%), Bullet tuna Auxis rochei (8.65%), Yellowfin Tuna Thunnus albacares (11.16%) and Indian Mackerel Rastrelliger kanagurta (16.25%). While 669 fish (54.08%) caught at deep FAD consisted of Katsuwonus pelamis (11.80%), and  Rastrelliger kanagurta (18.35%). The size spread of skipjack tuna (23-42 cm and 29-53 cm), Bullet Tuna (16.5-25.0 cm and 18.5-28.5 cm), Yellowfin Tuna (25-120 cm and 80-160 cm) and Indian mackerel (16-25 cm and 16-25 cm) for shallow and deep FAD respectively. The fish size distribution caught at shallow and deep FAD was skipjack tuna, whereas the  Auxis rochei rochei  and Thunnus albacares had bigger size distribution in deep sea FAD, while the  Rastrelliger kanagurta had relatively similar size distribution in shallow or deep sea FAD.   </p><p class="TubuhTulisanAll"><strong><em>Keywords:</em></strong><strong><em> </em></strong><strong><em> </em></strong><em>fish size, fish species composition,</em><em> </em><em>hand-line, shallow and deep sea FAD</em><em></em></p><p align="center"><strong>ABSTRAK</strong></p><p class="Abstrakisi">Penelitian ini bertujuan untuk menganalisis komposisi jenis dan ukuran ikan yang ditangkap pada rumpon laut dangkal dan rumpon laut dalam di Selat Makassar.
