Development Analysis

Kapasitas penangkapan adalah ukuran kemampuan yang dikerahkan oleh berbagai jenis unit penangkapan ikan yang tergabung sebagai suatu armada penangkapan ikan untuk memperoleh hasil tangkapan. Penelitian ini menganalisis trend dan kapasitas penangkapan ikan pelagis kecil di perairan pantai barat Sulawesi Selatan. Delapan jenis alat penangkap yang signifikan di Selat Makassar, perairan barat Provinsi Sulawesi Selatan adalah payang, pukat pantai, pukat cincin, jaring insang hanyut, jaring lingkar, jaring insang tetap, bagan perahu dan bagan tancap.  Produksi dari 8 unit penangkapan berdasarkan 6 jenis ikan pelagis kecil, yaitu (1) kembung (Rastrelliger sp), (2) layang (Decapterus sp), (3) lemuru (Sardinella longiceps), (4) selar (Selaroides spp), (5) tembang (Sardinella  fimbriata), (6) teri (Stolephorus spp). Total upaya penangkapan ikan tahunan dari kedelapan jenis unit penangkapan ikan tersebut dihitung untuk kurun waktu selama 20 tahun (1987-2006) dengan menerapkan standardisasi berdasarkan kemampuan setiap jenis unit penangkapan ikan.  Analisis dilakukan untuk mengidentifikasi trend CPUE dan kapasitas penangkapan ikan pelagis kecil menggunakan metode Peak to Peak Analysis di tiga zona perairan pantai, yaitu perairan laut dangkal  (zona A), perairan bentuk teluk (zona B) dan perairan laut dalam (zona C), Tren CPUE di ketiga zona menunjukkan cenderung menurun dalam kurun waktu 30 tahun, dimana tren menurun CPUE di zona C menunjukkan lebih besar dibandingkan zona lainnya.  Kapasitas penangkapan di zona A, perlu mereduksi jumlah unit penangkapan sebesar 6%, sedangkan di zona B sebesar 5% dan zona C sebesar 11% untuk mencapai produksi optimal.Fishing capacity can be regarded as a total mobilized capability made by fishing fleet to produce catch. This research analyze trend and fishing capacities of small pelagic fish in off west coast of South Sulawesi. There are 8 significant fishing unit operated in off west coast of South Sulawesi ; these are  payang, beach seine, purse seine, drift gill net, encircling gillnet, fixed gill net, boat liftnet, fixed liftnet.  The fish production data cover 6 types of fish, i.e. Indian mackerel, anchovy, sardines, scads, and trevally caught by 8 types fishing unit. Annual fishing effort and CPUE over a period of 30 years (1977-2006) were calculated after a standardization considering variability in capture capability and fisheries development.  Analysis was conducted for identifyng CPUE trend and fishing capacities of small pelagic fish using Peak to Peak Analysis. The study area was divided into three regions, i.e, around Spermonde Island  (zone A), off Polman and Pinrang district (zone B) and off Majene dan Mamuju district (zone C).  CPUE trend in three water zone showed to decrease for 30 year of period, where decreasing CPUE trend at zone C was higher than other zones.  Fishing capacities in zone A need to be reduced of fishing effort for  6%, whereas in zone B was 5% and zone C was 11%.

The Impact

Although researchers have investigated the impact of Indian Ocean Dipole (IOD) phases on human lives, only a few have examined such impacts on fisheries. In this study, we analyzed the influence of negative (positive) IOD phases on chlorophyll a (Chl-a) concentrations as an indicator of phytoplankton biomass and small pelagic fish production in the eastern Indian Ocean (EIO) off Java. We also conducted field surveys in the EIO off Palabuhanratu Bay at the peak (October) and the end (December) of the 2019 positive IOD phase. Our findings show that the Chl-a concentration had a strong and robust association with the 2016 (2019) negative (positive) IOD phases. The negative (positive) anomalous Chl-a concentration in the EIO off Java associated with the negative (positive) IOD phase induced strong downwelling (upwelling), leading to the preponderant decrease (increase) in small pelagic fish production in the EIO off Java.

Studies on the exploitation and catch fluctuations of pelagic fishes have been undertaken in order to understand the fishery systems, annual and seasonal change of fishing effort and catches, as well as species composition. The study was based on the daily monitoring data of the purse seiners. The results showed that generally the fishing activities is one day fishing, the increase of fishing effort reflected in the number of fishing units and the number of trip, while the trend of production and catch rate were fluctuated by either annual or seasonal; the peak of catch rate was occurred in 2007, 2008 and 2012 periods, during December to June were low catches, and are going in the peak season in September-October. The lowest catch rate is about 100kg/trip and the maximum of 4.3 tons/trip (the average of 1.3 tons/trip), however the fail of fishing was often occurs and reached 30% of the total number of trips; the failed fishing was decline from year to year. The catch rate (kg/trip/day) was showed a pattern fluctuations; the small pelagic fish mainly the scads (Decapterus spp.) and clupeids (Bali sardine, Sardinella lemuru), respectively 33% and17%, whereas the dominan large pelagic fish is ‘tongkol’/frigate tuna (Auxis thazzard). The changes of species domination was occurred either in annually or seasonally.

The Impact

Current South African government policy aims to create more equitable access to marine resources and there is pressure to increase the inshore gill-net fishing effort. At present, the gill-net fishery in the Western Cape is confined to the cool temperate west coast. In order to ascertain the potential catch if the fishery was to expand along the warm temperate south-west coast, a program of experimental netting was conducted. Estuarine and coastal marine sites were sampled bimonthly, using a range of commercial gill-nets (44–178 mm stretch-mesh). Although the target species, Liza richardsonii, dominated the catches, at least 33 of the by-catch species caught were also targeted by the commercial or recreational line-fish sectors. The number of species captured and the line-fish (by-catch) catch per unit effort (CPUE) were greatest in areas currently closed to the commercial gill-net fishery. Multivariate analysis indicated significant differences in catch rates and composition between exploited west coast and unexploited south-west coast sites. A combination of natural biogeographical trends and the impact of over 100 years of commercial gill-netting on the west coast are the likely causes of these differences. A spatial expansion of the gill-net fishery could have a detrimental impact on overexploited line-fish stocks and lead to increased user conflict.

Pelagic fish, including sardines and anchovies (Order Clupeiformes), are the most common species taken by artisanal marine fisheries along the Togolese coast. We investigated fisher involvement as well as fish captures over a period of 10 years, particularly of the European anchovy (Engraulis encrasicolus). Our results indicate that 60% of fishers operated from the Lomé fishing harbour, most fishers being Ghanaians working seasonally in Togo. 63.7% of all the fishers used canoes with outboards, a higher percentage compared to the previous decades. Seven fishing gear type were identified, with bottom gillnet and surface gillnet being the most commonly used. However, in the most important fishing camp in the country in terms of fish production (Lomé fishing harbour), all fishers used shark nets. Overall, fisheries catches did not change significantly across years, but anchovy fishing effort and catch per unit of effort (CPUE) declined over the study period, suggesting some depletion of the species stocks on the Togolese coast and a demotivation of fishers.

Sumber daya ikan di perairan Indonesia merupakan salah satu modal menuju kemakmuran bagi bangsa, apabila dikelola secara berkelanjutan.Kajian potensi dan tingkat pemanfaatan tahun 2015, merupakan salah satu dasar utama dalam merumuskan pengelolaan tersebut menuju pemanfaatan sumber daya yang lestari bagi kesejahteraan bangsa. Secara keseluruhan komposisi jenis sumber daya ikan di perairan Indonesia didominasi kelompok ikan pelagis kecil sebesar 36 % dan ikan pelagis besar sebesar 25 %. Potensi sumber daya ikan di perairan Indonesia adalah sebesar 9,931 juta ton per tahun dengan potensi tertinggi terdapat di WPP 718 (Laut Arafura) sebesar 1,992 juta ton/tahun (20%), di WPP 572 (Samudera Hindia sebelah barat Sumatera dan Selat Sunda) sebesar 1,228 juta/tahun (12 %) dan di WPP 711 (Selat Karimata, Laut Natuna dan Laut Cina Selatan) sebesar 1,143 juta ton/tahun (12 %). Tingkat pemanfaatan secara keseluruhan terlihat didominasi kondisi overfishing (indikator warna merah) sekitar 49 %, diikuti kondisi fully-exploited (indkator warna kuning) sekitar 37 % dan kondisi moderat (indikator warna hijau) hanya 14 %. Kelompok ikan yang mengalami kondisi overfishing paling tinggi adalah kelompok udang Penaeid, lobster, kepiting dan rajungan, yang mencapai 63 % dari kondisi overfishing saat ini. Dalam perspektif yang demikian, opsi pengelolaan yang harus segera dilakukan adalah mengurangi jumlah upaya penangkapan pada WPP yang mengalami kondisi overfishing serta meningkatkan upaya pada WPP yang tingkat pemanfaatannya masih moderat dan fully exploited.Fish resources within Indonesian waters (i.e. teritorial and archipelagic waters) including Indonesian Economic Exclusive Zone if under sustainably management it would contribute a significant role as a source of nation welfare. Scientific advice on stock status and its exploitation rate are required as an input to support an apropriate fisheries management. Generally, fish resources in these waters are dominated by two main fish groups such as small pelagic fish by 36 % and large pelagic fish by 25 %. Indonesia fish resource in 2015 was estimated for 9,931 million tons/year with comprises of 1,992 million ton/year (20 %) in fisheries management area (FMA) 718 (Arafura sea), 1,228 million/year (12 %) in FMA 572 (western of Sumatera of Indian ocean and Sunda strait) and 1,143 million tons/year (12 %) in FMA 711 (Karimata strait, Natuna sea, and south China sea). Most of fish resources (49 %) were in the status of overfishing with red indicator, folowed by fully-exploited state(37 %) in yellow indicator and only 14 % in the moderate state (green indicator). Among all nine fish groups, the overfishing state (up to 63%) is recorded from group of shrimps (Penaidae), lobster, and crabs. The management options in these prespective is urgently suggested to reduce fishing effort at the level of f.opt (fishing optimum) for overfishing fish groups. Whilts possibly to increase effort for fish groups with fully and moderate exploited state at the level off opt.
