Purse Seine Fishery

Due to very good collaboration with one commercial purse seiner, using “Srdelara” and operating in fishing zone G, preliminary data concerning the interaction between small pelagic purse seine fishery and its predators were obtained. According to the notes taken by experience observer on-board in period from year 2013 to 2016, seems that tunas, dolphins and swordfish were the faithful companions of purse seiner fisherman with abundance of 68.6%, 22.0% and 9.4%, respectively. Although they were present all year round, their monthly pattern of appearance indicated that less tunas were recorded in May-June, more dolphins were noted from July to October while swordfish were mostly abundant in winter (January-March). Within the investigated period, slightly increasing trend of tuna and dolphins’ appearance was recorded, although statistically not significant. Analysing possible correlation between purse seine catches and predator’s abundances, revealed that appearance of tuna had negative impact on the catches (dispersion of schools), while realised catches in presence of dolphins were quite good so it seems that they tend to round up small pelagic fish schools.

Pemanfaatan sumber daya ikan pelagis kecil di Laut Cina Selatan wilayah Indonesia (luasnya sekitar 595.000 km2), khususnya di perairan pantai Kalimantan Barat dengan sasaran utamanya ikan kembung (Rastrelliger brachyosoma) pada tahun 1991 telah mencapai 94% dari rata-rata hasil tangkapan maksimum lestari. Perkembangan penangkapan ikan pelagis kecil ke arah lepas pantai yang dirintis oleh armada pukat cincin Pekalongan sejak tahun 1985 di perairan Pejantan telah diikuti oleh nelayan Kalimantan Barat, khususnya di Pemangkat pada tahun 1990. Jumlah kapal pukat cincin Pemangkat yang pada tahun 1995 hanya enam unit, pada tiap tahunnya meningkat sampai mencapai 48 unit pada tahun 2003. Penelitian ini bertujuan untuk memperoleh gambaran perikanan pelagis kecil yang berbasis di Pemangkat dengan alat tangkap pukat cincin. Analisis dilakukan berdasarkan pada data log book tiap trip kapal pukat cincin pada periode tahun 2004 - 2006. Hasil tangkapan pukat cincin didominansi oleh ikan pelagis kecil, terutama 2 jenis ikan layang (Decapterus russelli dan D. macrosoma), bentong (Selar crumenophthalmus), banyar (Rastrelliger kanagurta), dan tembang (Sardinella gibbosa), serta jenis-jenis ikan lainnya yang bernilai ekonomis. Hasil tangkapan ikan pelagis kecil bervariasi menurut musim, yaitu paling tinggi pada musim peralihan 1 dan peralihan 2, serta paling rendah pada musim barat. Catch per unit of effort jenis-jenis ikan pelagis kecil dari tahun 2005 - 2006 pada umumnya cenderung turun, diduga akibat tingginya jumlah upaya dari banyak armada pukat cincin lain, baik dari wilayah Indonesia maupun dari luar negeri. Exploitation of small pelagic fish resources in the South China Sea of Indonesian region (around 595,000 km2) especially in the coastal waters ofWest Kalimantan Province which short bodied mackerel (Rastrelliger brachyosoma) as the main target had reached at a rate of 94% of the average of maximum sustainable yield. The development of fishing on small pelagic fishes toward off shore pioneered by purse seine fleet of Pekalongan (north coast of Java) since 1985 then followed by fishermen of West Kalimantan, especially in Pemangkat in 1990. The number of purse seine of Pemangkat that only 6 units in 1995 increased every year up to 43 units in 2003. The aim of this research was to describe small pelagis fishery in the Pemangkat landing site by purse seine. Analysis was conducted based on log book data of purse seiners during the period of 2004 to 2006. During the period of 2004 to 2006, the catch of Pemangkat purse seine was mostly small pelagic fish mainly composed of 2 species of scads (Decapterus russelli and D. macrosoma), big eye scad (Selar crumenophthalmus), Indian mackerel (Rastrelliger kanagurta), and fringerscale sardine (Sardinella gibbosa), also the other economic fishes. Both the catch varied between moonson. The highest catch was during the two intermoonsons and the lowest catch was during the west moonson. Catch per unit of effort of the small pelagic fishes from 2005 to 2006 mainly decreased, since the high amount of the efforts from purse seine fleets of the other locations of Indonesia as well as foreign countries.

Fish Catch

The purse seine is the dominant fishing tool at the Birea Fish Landing Base (FLB) which generally catches small pelagic fish. Handling fresh fish is an important part of the chain of the fishing industry. The problem that dominates fishermen and owners is the decline in the quality of fish caught due to fishing time at sea, so that preservation technology is needed that is able to maintain the quality of the fish longer from being caught until landed in the fishing port.The purpose of this study was to analyze the handling and quality of the purse seine fish catch and to analyze the handling and quality of the fish catch after landing from the purse seine ship. This research was conducted on a purse seine vessel in Bantaeng Regency from February to March 2020. Of the five vessels that were the object of research, vessels with better fish quality were vessels that used management with a ratio of 1: 1 meaning 1 kg for 1 kg of fish. The behavior management of fish traders in the market and the travel time from the fish caught to the market are factors that influence the effect of the decline in fish quality.

This study aims to analyze the economic value of small pelagic fishing fisheries in Indramayu Regency, West Java. This research was conducted by a survey method using a questionnaire with a purposive sampling method and the data were analyzed descriptively quantitative and qualitative. The benefits of the results of this study are expected to provide information for decision making for the relevant government in formulating policies on fisheries activities, especially small pelagic fish in Indramayu Regency West Java so that they remain sustainable. Catching small pelagic fish is done by purse seine, mini purse seine, Millenium gill net, fishing line, and nylon net. The majority of the ship size used ships with sizes below 20 Gross Tonnage (GT). The types of small pelagic fish caught are Anchovy, Mackerel, Long Jawed Mackerel, Sardine, Scad, Sand Whiting, Tanjan Fish, Rucah Fish and Japuh Fish. The highest acceptance value of small pelagic fish in 2019 is found in anchovies, which is 8.997 billion. So that the highest profit of the highest small pelagic fish obtained in 2019 is found in Anchovy, amounting to 8,780 billion. The Benefit-Cost Ratio (BCR) calculation shows that the BCR value for catching pelagic fish species above is> 1 so that the fishing activity is feasible and can be continued. 99.7% of small pelagic fishing activities are influenced by the GT of the ship, the number of trips (months), and the fishing gear based on the calculation of multiple linear regression analysis.

Abstract The purse seine is the dominant fishing gear operating at the Tumumpa Fishing Port with a vessel of >90%. The purse seines that have developed are large pelagic targets, with the main catch targets being skipjack, mackerel tuna, and tuna. Tuna, mackerel tuna and skipjack are important commodities for fisheries in Indonesia. This study aims to determine the characteristics of purse seine fishing gear and its catch in the Sulawesi Sea. Data collection was carried out for two years from 2019-2020 at Tumumpa Fishery Port. Indications for the use of fish resources are calculated by comparing the length-at-first-capture (Lc) with the length-at-first-mature (Lm). The results showed that purse seines are very dominant in exploiting large pelagic resources (skipjack, mackerel tuna and tuna) with the proportion reaching 78%, small pelagic (21% scads and 1% other fish). The large pelagic fishing season using the purse seine vessel occurs in May – November, with 2 peak seasons in July and September. While the small pelagic occurs in May – September, with the peak occurring in July. The size when the frigate tuna was first caught was at a fork length of 25.15 cm (Lc) and Lm in a size of 28.52 cm for females and 28.29 cm for males. Meanwhile, the first scads was caught (Lc) at a length of 21.4 cm with the length-at-first-mature (Lm) being 20 cm for the female and 19 cm for the male. Based on this analysis, it was shown that the purse seines is a selective fishing gear for small pelagic fish but not selective for large pelagic fish.

Fishing Capacity

Croatia has a fishing fleet of 7559 vessels. Of these, small-scale coastal fishing boats, less than 12 meters in length, makes up 95,7% of the fleet. However, the largest percentage of catches, more than 94%, is made by purse-seiners that are representing only 3% of total fishing vessels. These vessels target small pelagic fish, predominately sardine and anchovy. This paper describes all the technical characteristics of the Croatian purse seiner fleet, based on 113 purse seine vessels registe-red in 6 Croatian ports and targeting anchovy in order to allow a precise determination of that fleet fishing capacity and subsequent management of the fleet in a responsible and sustainable manner. Comparison of different technical characteristics showed that the length of a vessel corresponds to the amount of the catch as well as to size of the fish. Hence, results confirm superiority of sonar, as a fish-finding device, over sounder in detecting fish shoals, which is prerequisite for purse seine fishing.
