Distribution Of Fish

Distribution of small pelagis fish in FADs, and produktivity of FADs in AmFADs are usually used by fishermen to concentrate fish for an efficient catching activity. However, the number, distance, and distribution in the waters need to be assessed in relation to the productivity of the FADs in order to maintain the sustainability. This study was aimed to map the distribution of FADs; to analyze the distribution of species, number and size of fish associated with FADs; and to calculate FAD productivity based on distribution in the Outer Ambon Bay waters. Data was obtained by observation and interview. Field observation, including: coordinates and number of FADs, species, number and size of fish. The distance and distribution of FADs, was mapped using software (Argis web), while the productivity of FADs was analyzed base on catch per unit effort (CPUE). The result, FAD in Outer Ambon Bay waters was found 25 unit and the average distance of FAD was obtained 0.47 nautical miles, and the placement of the device was irregular. The placement pattern of FADs were generally straight to coastline. Small pelagic fish was found 7 species and the 5 of the dominant species were obtained Decapterus sp, Selar crumenophthalmus, Rastreliger sp, Sardinella sp and Selaroides sp. The species were unevenly spread at each FAD with quite varied sizes. FAD productivity showed that the highest productivity was found in the middle group FAD at Ambon Bay waters.Keywords: Distance, size, small pelagis, productivitybon Bay

Fish Harvest

Despite the magnitude of domestic and industrial pollution, fishery yield registered in several landing points at Guanabara Bay, between April 2001 and March 2002 was slightly over 19,000 tons, corresponding to a value of US$ 4.8 million. When considered only the fish directed to the food market, the total catch amounted to about 6,300 tons and a value of US$ 3.7 million. Only a few fish species reached expressive densities compatible with commercial fisheries. Among small pelagic fish, Atlantic anchoveta and Brazilian sardinella were the dominant species, while in terms of demersal fish, croakers, mullets and catfishes comprised the main part of the catch. The absence of landing data previous to the spilling of 1.3 million liters of oil in January 2000 led to claims by fishermen representative organizations of values corresponding to about 50 years of fish harvest in the bay. Possibly, a data collection network could be established in a participative way with the main fishermen local associations. The relatively stabilized fisheries in the bay suggested that reasonable inferences could be made, without, necessarily having a complete coverage of all landing points.

Penelitian ini bertujuan untuk mempelajari distribusi spasial kepadatan ikan pelagis serta hubungan dengan kondisi perairan pada musim peralihan di perairan pantai utara Jawa bagian timur dan Laut Flores, berdasarkan pada pengambilan contoh akustik dan 34 stasiun oseanografi pada bulan Oktober 2005. Data target strength menunjukkan bahwa rata-rata ukuran ikan pelagis yang terdeteksi di perairan pantai utara Jawa bagian timur adalah 10 sampai dengan 56 cm. Ukuran ikan di daerah lepas pantai lebih kecil dibanding daerah dekat pantai. Pada musim peralihan, kondisi suhu dan salinitas perairan relatif homogen. Sehingga faktor tersebut kurang signifikan terhadap distribusi keberadaan ikan. Diduga faktor lingkungan lain seperti faktor biologi dan kimia, berperan dalam pola penyebaran ikan pelagis kecil di perairan ini. Di Laut Flores dan sekitar Pulau-Pulau Sunda, densitas ikan tertinggi pada stratum 10 sampai dengan 50 m dengan ukuran 10 sampai dengan 20 cm terutama di beberapa lahan marginal seperti sekitar selat dan kepulauan. Selain merupakan lapisan tercampur di mana kondisi suhu dan salinitas relatif stabil pada kedalaman 10 sampai dengan 50 m, lahan marginal merupakan daerah subur tempat pertemuan 2 massa air yang berbeda yang membentuk front diharapkan merupakan tempat berkumpul ikan. Lapisan termoklin yang bersifat lemah berada di bawah 50 m, hal ini mempengaruhi densitas ikan yang semakin rendah pada kedalaman lebih dari 50 m. Ikan pelagis yang berada pada lapisan termoklin mempunyai ukuran yang lebih besar yaitu 14 sampai dengan 40 cm. Pada musim yang sama, rata-rata kepadatan dan ukuran ikan pelagis kecil di wilayah timur lebih rendah daripada sebelah barat. The aim of this research is to study the distribution of spasial density of pelagic fish with waters condition at intermonsoon in north of Java coast waters part of east and Flores Sea, based on acoustic sampling and 34 oceanography stations in October 2005. The target strength of fish indicated that pelagic fish measure in north of Java coast waters part of east is about 10 to 56 cm. Fish sizes in offshore is smaller than near shore. At intermonsoon, the waters condition of temperature and salinity was homogeneous relatively. Therefore, that are less to distribution of fish density. Anticipated, the others environmental factor like chemical and biological, was influenced to distribution of small pelagic fish in this area. In Flores Sea and Sunda Islands, the highest of fish density at 10 to 50 m and fish sizes about 10 to 20 cm especially in some marginal areas near archipelago and strait. At 10 to 50 m is mixed layer, where temperature and salinity was relative stabilize, the maginal areas is fertility waters which is passage of the shifting by two different water masses and front were formed . The weak termocline was formed below 50 m, maked fish density are progressively lower below 50 m. The pelagic fish residing in termocline layers have larger ones measure than stratum 10 to 50 m is about 14 to 40 cm. On same season, the fish measure and density of small pelagic fishes in east region is lower than at westside.

Nelayan penangkap ikan yang efektif membutuhkan informasi sumberdaya ikan dan pola penyebarannya. Penelitian ini bertujuan untuk mengetahui pola sebaran sumber daya ikan yang dikaitkan dengan kondisi oseanografi WPP-NRI 715. Analisis dilakukan berdasarkan kombinasi metode hidroakustik dan profiling CTD pada stasiun oseanografi yang dirancang secara parallel pada jarak tertentu di lintasan tersebut. Hasil penelitian menunjukkan, estimasi ukuran ikan pelagis yang terdeteksi didominasi oleh ukuran kecil. Ikan pelagis kecil yang terdeteksi didominasi ukuran ikan antara 12-14 cm dan ikan pelagis besar ukuran ikan 28-31 cm. Kepadatan ikan pelagis kecil cenderung menurun dengan rerata faktor 0,4 dengan bertambahnya kedalaman, sebaliknya meningkat dengan rerata faktor 1,7 untuk ikan pelagis besar. Pada saat observasi, dikawasan perairan Laut Maluku bagian timur diindikasikan terjadinya upwelling ditandai dengan suhu rendah, salinitas tinggi, dan klorofil tinggi. Ikan pelagis besar lebih banyak ditemukan pada lokasi yang memiliki karakteristik suhu dan DO yang relatif lebih tinggi sedangkan salinitas lebih rendah dibandingkan dengan lapisan air yang didominasi ikan pelagis kecil. Informasi pola sebaran ikan pelagis ini diharapkan dapat dijadikan rujukan bagi pelaku perikanan tangkap dan masukan untuk bahan perumusan kebijakan pengelolaan perikanan tangkap yang berkelanjutan.Effective commercial fishers need information on fish resources and their distribution pattern. This study aims to determine distribution of fish resources in Indonesian FMA 715 through tracking hydroacoustic method and CTD profiling at stations within regular distances. The results showed that the estimated size of pelagic fish was dominated by small size fish groups. Small pelagic fish were detected at the size ranged between 12-14 cm and large pelagic fish was dominated by the size of 28-31cm. The density of small pelagic fish decreases with depth with average factor of 0.4, while the large pelagic fish with average factor of 1.7.  An indicated upwelling incidence was likely occurred in the eastern part of Mollucas sea region, which were characterized by the low temperature, high salinity and high chlorophyll concentrations. Large pelagic fish were more occasionally found in locations with relatively higher temperature, DO characteristics and lower salinity compared with small pelagic fish. Information on the distribution pattern of pelagic fish is expected to be used as a reference for capture fishermen and inputs in formulating the policy the sustainable fisheries management.

Abstract Stockwell, J. D., Weber, T. C., Baukus, A. J., and Jech, J. M. 2013. On the use of omnidirectional sonars and downwards-looking echosounders to assess pelagic fish distributions during and after midwater trawling. – ICES Journal of Marine Science, 70:196–203. Small pelagic fish can play an important role in the structure and function of ecosystems, and there is increasing interest in their non-market value. At the scale of fish aggregations, however, the impact of fishing has received relatively little attention, with most effort devoted to impacts of vessel and gear avoidance on stock size estimates. We used concurrent deployment of a downwards-looking echosounder (Simrad ES60 system) and an omnidirectional sonar (Simrad SP90 system) during commercial pairtrawling operations for Atlantic herring (Clupea harengus) in the Gulf of Maine to examine their potential for studying the impacts of fishing on herring aggregations. We compared a number of aggregation metrics to illustrate similarities and differences between the two systems, and then qualitatively examined their properties during and after pairtrawling events to illustrate potential applications. Our results suggest that using both downwards-looking and omnidirectional systems provides complementary information on fish aggregation metrics. Future applications of these systems in before–after–control-impact (BACI) designs may help inform management agencies when evaluating potential impacts of fishing at the time and space scales of pelagic fish aggregations.

Barru Regency has various potentials for capture fisheries, including small pelagic fish such as flying fish (Decapterus spp). Until now, fly fishing in Barru Regency is still open access. So it is necessary to monitor the catch per unit effort. The identification of the type of catch is done visually. Data processing through the Schaefer Model approach. The results showed that the sustainable potential of flying fish in the waters of Barru Regency, Schaefer model (1954), was 6774.59 tons, the maximum sustainable fishing effort (fMSY) was 384 units. Meanwhile, JTB for the sustainable potential of flying fish is 5419.67 tons with a maximum number of fishing effort units of 212 units / year. The status of the utilization of flying fish resources in Barru Regency waters has been categorized as dense exploitation with a high level of cultivation. Even though they have not passed the MSY and Fopt values, caution is needed in their use.

Small pelagic fish resources in the Java Sea, especially Banyuwangi, are dominated by catches of Decapterus sp, which are mostly landed at the UPT of the Coastal Fisheries Port Muncar. This study aimed to provide information on CPUE trends (Catch Per Unit Effort) and the seasonality of flying fish in the Coastal Fisheries Port Muncar as an effort to encourage effective and sustainable in using of fishery resources. The method used in this study was a survey. The research data was obtained through secondary data including time series of the production of catches of flying fish, and trip data of purse seine, payang and bagan from 2015 to 2019 collected by Coastal Fisheries Port Muncar. The analysis used the CPUE analysis by comparing catches to capture attempts. The results showed, from 2015 to 2019, the highest CPUE of flying fish occurred in 2019, amounting to 13 365.5 kg/trip, while the lowest CPUE occurred in 2016 amounted to 1 050.6 kg/trip. The trend of CPUE flying fish from 2015 to 2019 experienced a fluctuating increase with an average of 7 327.5 kg/trip. A good season for flying fishing occurs from May to December, and shares a peak in December, while famine occurs in January.
