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.

The multiple-use Moreton Bay Marine Park in eastern Australia was rezoned in 2009, increasing the total no-take marine national park (MNP) from 0.5 to 16%. In the present study we measured trends in the human use of no-take areas using observed vessel position and categorisation during on-water and aerial surveys before and after rezoning. Measured changes in spatial patterns of fishing showed that the effects of rezoning on most fishing activity was minimal. After rezoning, the proportion of recreational fishing declined from 6.3 to 2.6% of the footprint in the new MNPs. The proportion of commercial fishing declined from 25 to 1%, although the amount of commercial fishing was low. There was an overall increase in fishing activity on Moreton Bay. Low recreational fisher displacement suggests that the expansion of the MNP area did not have a high social cost. However, most of the no-take zones were areas not previously subject to high recreational fishing pressure. If a significant proportion of the no-take zones were placed in areas of low ecological production, the biodiversity conservation impact achieved by the rezoning of Moreton Bay may have been less than the 16% increase in no-take areas would imply.

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.
