The purpose of this study was analyze the biological reproduction of P. tile which induced sex ratio, gonadal maturity level, gonadal maturity index and size at first maturity. Data collection was carried out from October to December 2022. The data collection method was conducted using experimental fishing methods by operating unit gill net with mesh size of 1,75 and 2,0 inch. Fish samples of each actual fishing were measured total length and weight, dissected to determine sex, measured gonad weight and determined the level of gonadal maturity. The results showed that the sex ratio of male fish was higher than female fish. The GML phase is in phases I-V where the immature gonads are more dominant than the mature gonads, the GSI increases as GML increases. The size at first maturity for males is 20.6 cm and 18.6 cm for females.

Five of the ten brokers in that market were taken as samples and observed as well as interviewed in depth. The results show that the role of the Brokers in the fresh fish marketing process, especially in that market, which is known as the main traditional market in Ambon is very large. It can be seen from the percentage of fish passing through them. Approximately 90% of the fishermen’s catch (especially purse seine) must pass the brokers for further distribution to consumers through retailers. For this job, they will earn 10% of fishermen’s sale, both those distributed to retailers and those sold to Cold Storage. Some fishermen argue that the existence of broker is very helpful in the marketing process, but some fishermen also complain about their presence in the market. When fishermen experience problems and need assistance (money), the broker will immediately reach out to help. The assistance must still be r...

Quality control is a necessity to keep the freshness of fish and the prime nutritional quality. In this study interview and observation were done on the focus group to investigate quality control activities carried out by the artisanal fisher community. In many places in Maluku, small pelagic fish caught by using purse seine net. The fishing ground is relatively close to the landing site at the coastal area and landed in 1-2 hours after death. Shortly after landed ice treating is applied on the fishes with the ratio of ice to fish roughly 1:2 and also a small amount of clean sea water added onto the fish-ice mixture in order to chilling fish and keep it fresh. Most fish are transported to the central market in town by using cars which takes one to two hours, and the rest taken by the small retailers and distribute to the closest markets in the village....

However, biological information about this species has been poorly documented. Our current study focused on the growth and morphometric relationships of spawning cohorts during spawning season (June to October 2013). Flyingfish which were trapped in bale-bale, an egg aggregation device for flying fish, were collected offshore of the Southeastern Seram Sea. Total samples of 1693 with Fork Length (FL) ranged from 156.15mm to 245.52mm and total weight from 53.15gr to 115.45gr. Von Bertalanffy growth functions (L∞) for-pooled sexes were FL = 251mm [1-e (1.82 (t+0.060)], K=1.82 and t0 = 0.060. Morphometrically, significant differences were observed for all individuals between sexes (F=14.20, P=0.0002), sampling locations (F=88.48 P<0.0001) and sampling period (F=138.84, P<0.0001). Condition factor of the fish generally declined in July-August. During spawning season, this fish tended to form single spawning cohort. The results of this study provide a significant understanding of the life history of this valuable fish inhabiting this particular region that rarely receives scientific investigation. For management purposes, harvesting eggs including broodstocks will lead to critical population depletion.

Laut Seram termasuk daerah penangkapan sumberdaya ikan terbang yang baru, sejak ditemukan pertama kali oleh Daeng Ngerang pada tahun 2001 dan telah dimanfaatkan sampai sekarang. Namun disayangkan masih belum diketahui sejauh mana tingkat pemanfaatan sumberdaya ikan ini terkait dengan perkembangan jumlah kapal dan kapasitas alat tangkap yang digunakan. Penelitian ini bertujuan untuk menganalisis trend CPUE tahunan dan potensi MSY serta trend CPUE bulanan. Pengumpulan data tahun 2001-2013 melalui review data Dinas Kelautan Perikanan Fak-Fak Papua Barat dan diverifikasi dengan mewawancarai beberapa nelayan, punggawa dan eksportir terkait dengan data upaya dan hasil tangkapan. Sedangkan data bulan Juni-Oktober 2013 diperoleh dengan mengikuti langsung nelayan di lapangan. Hasil yang didapatkan menunjukan terjadi penurunan nilai CPUE dengan puncaknya pada tahun 2007 dengan tingkat pemanfaatan potensi MSY terendah yakni -484641 kg, dan nilai MSY 402269 kg serta upaya optimal 614 unit kapal. Sedangkan produksi bulanan alat tangkap rumpong hanyut tahun 2013 menghasilkan rata-rata telur sebesar 149,4 kg/trip dengan total produksi 747 kg/musim. Jika dibandingkan dengan rata-rata produksi tahunan pada tahun yang sama yakni 561 kg/unit maka tingkat pemanfaatan sumberdaya ikan terbang di Laut Seram tergolong dalam tahap berkembang. Hasil penelitian ini diharapkan menjadi acuan pengelolaan dan pemanfaatan sumberdaya ikan terbang di Laut Seram dengan membatasi jumlah kapal sesuai hasil analisis.
