The fishing ground is identical and closely related to chlorophyll-a abundance in the waters, associated with its fisheries potential. This research has been conducted to determine the concentration and distribution of chlorophyll-a in the seas, especially in the Fisheries Management Area (FMA) 712 encompassing the Java Sea. The analysis used monthly time-series data collected from the satellite imagery over the last 11 years, taken through the ERDDAP website. The mean concentration of chlorophyll-a in the study area was 1.13 mg/l in June 2013. Based on 11 years of data processing, it can be concluded that the highest concentration of chlorophyll-a occurred in the west monsoon season from November to April, where increased rainfall caused the nutrient wash from terrestrial to the open waters. The lowest chlorophyll-a concentration happened in the east monsoon season from April to November, where the dry season arrived. The existence of pelagic fishes in FMA 712, such as Sardinella Lemurs and Sardinella Fimbriata, in waters highly influenced by the chlorophyll-a concentration, while Thunnus Sp. and Exocoetidae Sp. not affected significantly to the existence of chlorophyll-a concentration and its distribution.

Ecological Consideration

Pengertian dasar untuk pengelolaan perikanan terkait dengan fungsi fungsi biologi, sosial, teknologi, ekonomi serta lingkungan sumber daya sebagai komponen yang saling berhubungan untuk terjaminnya pengelolaan secara berkelanjutan. Stok ikan, ekosistem dan masyarakat nelayan merupakan salah satu kesatuan yang tidak dapat dipisahkan dalam sistem yang dinamis, dimana perubahan taktik dan strategi pemanfaatan masih merupakan suatu hal yang banyak dilakukan dalam rangka penyesuaian antara faktor teknis dan ekonomis yang sering kali mengabaikan pertimbangan bio-ekologi sumberdaya ikan. Sasaran pendekatan dan kebijakan pengelolaan perikanan di berbagai negara sudah mulai berubah, diawali dengan pendekatan memaksimalkan tangkapan tahunan dan ketenaga-kerjaan menuju ke konservasi dan pengelolaan berbasis pelayanan ekosistem. Konsep pengelolaan berbasis masyarakat dan ko-manajemen masih terbatas pada pengelolaan kawasan konservasi dan habitat terumbu karang. Adanya kesenjangan dan perbedaan antara kepentingan kawasan konservasi sebagai akibat kurangnya pemahaman kolektif terhadap tujuan pengelolaan, dan kerapkali menyebabkan aktifitas perikanan tangkap sebagai bagian dari kebutuhan ekonomis berbenturan dengan fungsi kawasan konservasi dalam jangka panjang. Pengendalian upaya penangkapan dan memahami dinamika perikanan, serta mengelola nelayan menjadi prioritas untuk pengelolaan sumber daya ikan, sedangkan konsep pengelolaan berbasis masyarakat dan ko-manajemen ditempatkan sebagai pelengkap untuk menutupi kelemahan aspek legal wilayah pengelolaan perikanan atau sumber daya ikan.Basic understanding of fisheries management related to biology, social, technology and economic function of fish resources. Fish stocks, ecosystem and fishers community are the integrated component under the dynamic of fisheries system, where as changing and on fishing tactic and strategy still exist to adjust between biology, technics and economics aspects. It is obvious that all technological creeps oftenly ignored the bio-ecological consideration of fish resources. The fisheries management and its policy were gradually shifting from maximize the catch, job opportunity become conservation and ecosystem based fisheries management. The concept of community-based management and co management is still limited to the management of conservation areas and coral reef habitats. The existence of gaps and differences between the interests of the conservation area as a result of a lack of understanding collective to the management objectives and often causing fishing activities as part of the economic needs clash with the function of conservation areas in the long term. Control efforts to capture and understand the dynamics of fisheries, as well as managing fishing is a priority for the management of fish resources, while the concept of community-based management and co management issued as a supplement to cover the weakness of legal aspects of the fishery management area or fishery resource.

This study aimed to map the oceanographic conditions and, based on that, to determine the favorable condition of skipjack tuna fishing ground in Fisheries Management Area (FMA) 713. This condition includes sea surface temperature (SST) and chlorophyll-a concentration. The primary data, such as fishing ground position and fish catch per trip, was collected by following the fishing operations that utilized pole and line (in Bone Gulf and Flores Sea) and purse seine fishing operations (in Makassar Strait). The secondary data, such as SST and chlorophyll-a, was derived from oceanographic satellite image data. The result showed that from January to August 2019, the skipjack tuna tends to occupy off shore areas where the sea surface temperature is between 29 - 29.5 oC and the chlorophyll-a density is between 0.10 to 0.15 mg.m3.

The Relationship

Abstract Cendrawasih Bay and the Pacific Ocean are known as potential fishing areas and as fish spawning locations in Fisheries Management Area 717. Larval dispersal in the waters is strongly influenced by oceanographic parameters. This study was conducted to examine the relationship between oceanographic parameters and fish larval dispersal in FMA 717. This research was conducted using KR Bawal Putih III in November 2019. A number of 42 stations were determined for observation. Environmental parameters included temperature, salinity, dissolved oxygen, chlorophyll-a, turbidity, and photosynthetic active radiation (PAR), were measured using SBE 19 plus V2 CTD while pelagic fish larvae were collected using a bonggo net. Analysis of the correlation of oceanographic parameters with pelagic fish larvae abundance and spatial distribution was calculated using PCA (Principal Component Analysis) statistical analysis. The results showed that the pelagic fish larvae was influenced by temperature, salinity, PAR, chlorophyll-a, turbidity, and DO. Temperature and salinity have a direct interaction to the abundance of pelagic fish larvae.
