ABSTRAKChaetognatha atau cacing panah (arrow worm) merupakan salah satu kelompok holoplankton yang distribusi dan keragamannya cukup tinggi di perairan. Chaetognatha memiliki peran yang sangat penting didalam rantai makanan dan juga berfungsi sebagai bioindikator kondisi oceanograf suatu wilayah. Kelimpahan Chaetognatha di dalam perairan dapat mempengaruhi kelimpahan larva ikan dan zooplankton lainnya, sehingga informasi keberadaannya sangat penting dalam pengelolaan perikanan. Penelitian ini bertujuan untuk mengetahui keragaman, distribusi dan kelimpahan Chaetognatha di perairan pesisir Kota Dumai Provinsi Riau. Penelitian ini dilaksanakan pada bulan April hingga September 2021 di perairan pesisir Kota Dumai. Jumlah stasiun pengambilan sampel sebanyak tiga titik dengan jumlah pengambilan sampel sebanyak dua kali pada masing-masing stasiun. Jumlah jenis Chaetognatha di perairan pesisir Kota Dumai tergolong rendah hanya ditemukan 2 jenis yaitu Eukronia calliops dan Sagitta megalopthalmus. Distribusi Chaetognatha di perairan Kota Dumai cukup merata dan ditemukan di ketiga lokasi penelitian walaupun kelimpahan yang relatif berbeda. Kelimpahan Chaetognatha berkisar antara 19-322 ind/1000 m3, namun jika dibandingkan dengan perairan lainnya, kelimpahan dilokasi studi sangat rendah.Kata kunci: Chaetognatha, keragaman, Kota Dumai, perairan pesisirABSTRACTChaetognatha or arrow worms are one of the holoplankton groups whose distribution and diversity is quite high in waters.

Togok is a fishing gear in the form of a conical net body whose arms are on two poles and the success of catching it relies on currents, togok fishing gear is used to catch Rebon shrimp (Acetes japonicas) but in its operation, many catches are found bycatch. The high bycatch will have an impact on capture sustainable fisheries, one of the efforts to reduce bycatch is by using BRD (Bycatch Reduction Devices), the use of BRD has been widely carried out on trawl fishing gear but on togok fishing gear, it has never been done. This study aimed for knowing the reduction in catches of main catch, bycatch, and discard the togok fishing gear that has been installed with rope BRD and knows the reduction in catches of shrimp and fish species. This study uses experimental fishing, namely by carrying out direct fishing operations with local fishermen for 20 days of catch. The reduction of togok catch using BRD type rope BRD in the main catch is 8.4%, in bycatch is 11.8% and discard is 17, 1% and the reduction in catch of shrimp species ranged from 8,4% - 13,5% and reduction in catch of fish species ranged from 10,9% - 22,6%.

Kapal gillnet termasuk kedalam kategori kapal static gear yang dalam pengoperasiannya lebih mementingkan stabilitas yang baik dan area kerja yang luas daripada kecepatan kapalnya. Rasio dimensi utama dapat menggambarkan karakteristik suatu kapal. Karakteristik tersebut mencakup performance aspek penting diantaranya: stabilitas, olah gerak kapal, tahanan, kemampuan muat dan aspek teknis lainnya yang tergambar dalam nilai rasio dimensi utama. Informasi mengenai karakteristik kapal penangkap ikan perlu diidentifikasi sebab kapal menjadi salah satu faktor penentu keberhasilan nelayan dalam mendapatkan hasil tangkapan. Penelitian ini bertujuan untuk mengidentifikasi karakteristik dimensi utama kapal gillnet udang mantis di Kampung Nelayan, Jambi. Pengumpulan data dilakukan bulan November sampai Desember 2018. Metode yang digunakan adalah survey dengan melakukan pengukuran L, B, dan D secara langsung di lapangan dan melakukan wawancara terhadap nelayan gillnet udang mantis. Hasil penelitian menunjukkan bahwa kapal gillnet udang mantis di lokasi penelitian memiliki dimensi utama hampir sama atau tidak jauh beda. Nilai dimensi utama menunjukkan, L/B berkisar 4,32-6,07, L/D berkisar 5,59-8,70, dan B/D berkisar 1,15-1,55. Nilai-nilai perbandingan tersebut masih berada dalam rentang nilai rasio dimensi utama kapal static gear di Indonesia. Pada nilai B/D perlu mendapat perhatian karena memiliki nilai perbandingan yang kecil yang berpengaruh pada stabilitas kapal menjadi kurang baik. Meski demikian, sejauh ini kapal yang digunakan mampu menunjang pelaksanaan aktivitas penangkapan udang mantis di lokasi penelitian.

Mantis Shrimp is one of economically important species due to its high value for export commodities. Mantis shrimp fishing in Kuala Tungkal is categorized as small-scale fisheries. This study aims to investigate the spatial distribution of mantis shrimp catches, both the number (individuals) and body length (BL) (cm) based on the distance from the shoreline to the fishing ground. A survey method was conducted in Kuala Tungkal, Tanjung Jabung Barat Regency, Jambi Province in December 2018. The observation covered 23 fishing trips by gillnet within 437 km2. The results revealed that the spatial distribution of the average number (individuals) of mantis shrimp in various stratifications reached 28-31 individuals. However, the farther fishing ground with higher salinity levels obtained a larger average size of mantis shrimp body length (BL). In the 0-4 mile stratification, it was found that the average catch size is 17.3 cm under the first maturity size which should be 19 cm. Meanwhile, in average the observed water condition as follow temperature is 28.2oC, DO = 7.4 mg/L, pH = 7, brightness = 1.1 m, and salinity is 20.9 ppt. At the end, the result of this spatial distribution may become an input for coastal resource management strategies and can support sustainable mantis shrimp fishing efforts.

Data on bycatch in the fishing effort required to manage fisheries resources. Unfortunately, the data on small-scale and traditional fisheries is still lacking. It makes it challenging to make fishing policies and regulations. Survey activities and experimental fishing were conducted to determine and analyze the composition of the main catch, bycatch and discarded by the local fisher's bottom traps in Sibolga, North Sumatra, Indonesia. Five units of the trap with a size of 150 cm x 100 cm x 50 cm (length x width x height) were used to collect fish data. These five trap units operated in the fishing ground, where local fishers usually operate their fishing gear. The fishing operation carried out within 1 mile of the coastline with water depths ranging from 7-10 meters. The duration of trap setting around 5-7 days for each fishing operation. A motorboat operated with a weight of 5.8 GT. The results showed that the total bottom trap catch consisted of 329 individuals with a total weight of 151.4 kg and 12 demersal fish species. The main catch was 148 individuals (88.9 kg), or 44.7% of the total catch during the experiment i.e. Chepalapholis urodeta, Ephinephelus areolatus, Epinephelus chlorostigma, Plectropomus leopardus, Ephinepelus coioides, Lates calcarifer, Lutjanus malabaricus, and Lutjanus erytropterus. The bycatch was 151 individuals (57.1 kg) or 46.1% i.e. Lethrinus obsoletus, Lutjanus ehrenbergii, Acanthurus auranticavus, Platax teira, Nemipterus japonicus, Scarus rivulatus, Lutjanus johnii, Siganus canaliculatus, Caesio cuning, and Taeniura lymma.While the discarded catch amounted to 30 individuals (5.4 kg) or 9.2% i.e. Naso brevirostris, Diodon holocanthus, and Diadema setosum. The bycatch utilization obtained by fishers was 83.4%, and the unutilized was 16.6%. The percentage of fish sizes worthy for consumption was 135 individuals (74.6%), and the size unworthy for consumption was 46 individuals (25.4%).Keywords:Fishing groundFishing gear Fishing operation Main catchTrap

One effort to reduce bycatch in togok is to modify the togok by creating a vent to reduce bycatch by BRD. The BRD installed on the togok was a rope BRD vent made of Polyethelene (PE) with a diameter of 2 mm. The rope BRD vent is attached to the top of the cod-end as an escape vent 25 x 50 cm. The escape vent and the stash cod-end are covered with a net with a mesh size of 5 mm. The cover net aims to collect data on fish catches that pass through the rope BRD vent. The percentage of fish that pass through the rope BRD vent can be calculated, and measure the size of the fish caught in the cod-end and covered as an indicator of the effectiveness of the rope BRD vent on togok. This experiment was carried out for 20 days of fishing operation and 40 hauls. The results showed that the catch of togok without rope BRD vent (conventional) and togok with modified rope BRD vent were different (p 0.05), where the catch of conventional togok was 468.34 kg, and the catch of modified togok was 305.235 kg. The fishing catches in the cod end and cover sections the most are bycatch with 51% and 54% of the percentage of the total catch, and the least in the cod end is the discarded catch, which is 21% of the percentage of the total catch and on the cover is the main catch (main catch) with 19% of the percentage of the total catch.The average size of the catch of togok species of fish is there are many immature sizes, and the average size of the catch of togok species of shrimp is there are in maturity size.Keywords:BycatchBycatch excluder device (BRD)DiscardMain catch
