Catching flying fish in Sendana Majene Subdistrict is carried out continuously with gill nets 1-1.5 inches. The catch of flying fish is mostly still young fish (not yet worth catching). The demand for flying fish is quite high due to the existence of special stalls of smoke fly fish around fishing settlements. Apart from smoke flying fish, dried flying fish are also sold as souvenirs. Therefore, fishermen will continue to increase production. Various results of research and field observations show that gill net is able to catch flying fish well but the size of fish caught is dominated by young fish. The effort to increase the net mesh size to 1.5 inches resulted in the diminishing number of young flying fish. Catching flying fish in Majene waters is generally carried out with drifting gill nets with mesh sizes of 1 and 1.25 inches which are very intensive every fishing season while L50 (11.92 cm) and Lm (13.59 cm) for 1 inch more net mesh size were smaller compared to the length of the first gonad maturity, in this case most of the catch is still classified as young fish (Palo, 2009). Partners are a group of flying fish fishermen. Partner problems, flying fish production is getting smaller, group capacity is not strong and group management is still weak. Partners have not been able to obtain assistance facilities from various community empowerment programs carried out by the government. The approach to be used in this service includes: identification, observation, counseling, demonstration, construction, application, assistance, field observation and evaluation monitoring. Indicators of the success of activities are measured based on the results of the application of technology compared to the results of fishing gear commonly used by fishermen. Implementation of service includes counseling, construction of fishing gear, fishing operations and assistance has been going well. The size of 1.5-inch mesh is only able to catch flying fish in a limited amount, while the size of the 1.25-inch mesh can catch flying fish in relatively large numbers. Flying fish caught with 1.25-inch mesh size has passed the size of the first gonad mature so that it supports sustainable fisheries.

Destructive Fishing

Peristiwa overfishing semakin marak terjadi di beberapa wilayah perikanan Indonesia akibat penggunaan alat tangkap yang merusak (destruktif). Jika hal ini terus dilakukan, maka kelestarian sumberdaya dikhawatirkan akan semakin menurun. Maka dari itu dibutuhkan strategi agar usaha perikanan tangkap ramah lingkungan secara ekologi dengan cara mengidentifikasi alat tangkap berdasarkan kriteria Code of Conduct for Responsible Fisheries (CCRF). Tujuan dari penelitian ini adalah untuk menganalisis alat tangkap ramah lingkungan di PPI Celong berdasarkan Sembilan kriteria CCRF. Metode penelitian yang digunakan adalah deskriptif mengenai alat penangkapan ikan yang ramah lingkungan di Pangkalan Pendaratan Ikan (PPI) Celong pada bulan Desember 2017 dengan wawancara dan observasi lapangan. Responden diambil secara sensus sebanyak 121 orang. Hasil analisis ramah lingkungan menghasilkan skor 17,87 pada arad, 27,44 pada trammel net, dan 28,40 pada gill net. Kesimpulan yang diperoleh dari penelitian ini adalah status alat tangkap arad tidak ramah lingkungan, trammel net ramah lingkungan, dan gill netsangat ramah lingkungan. Arad termasuk dalam kategori tidak ramah lingkungan karena cara pengoperasiannya yang tidak selektif dan merusak dasar perairan. Overfishing are increasingly prevalent in some Indonesian fishery areas due to the use of destructive fishing gear. If it continues, then the sustainability of resources feared will decrease further. Therefore a strategy is needed for eco-friendly fishery business by identifying fishing gear based on the criteria of Code of Conduct for Responsible Fisheries (CCRF). The purpose of this research is to analyze the eco-friendly fishing gear at Celong Fishing gear based on Nine criteria of CCRF. The research method used is descriptive of eco-friendly fishing gear at Celong Fishing Port in December 2017 with interviews and observations. Respondents who were taken by census was 121 respondents. The results of eco-friendly analysis resulted in a score 17.87 for  arad, 27.44 for trammel net, and 28.40 for gill net. The conclusions obtained from this research are arad status is not eco-friendly, trammel net is eco-friendly, and gill net is very eco-friendly.

This study was carried out in Oguta Lake, Imo State, Nigeria, from January, 2012 to December, 2013 at five stations (Onu Utu, Okposha, Ogbe Hausa, Osemotor and Ede Ngwugwu) to ascertain the percentage abundance and catch rate of gear and craft. The average weight of fish caught per canoe per day ranged between 3.2 kg for Basket and Drum traps to 47.1 kg for boat seine net. The gill nets ranged between 6.0 to 13.0kg per canoe per day with mean weight of 8.60±2.91kg, the cast net had values ranging from 1.0 to 7.0 kg with a mean weight of 4.3±2.49 kg. Lift net yielded an average of 3.4 kg per canoe per day. Gill nets were the main gear used by fishers, followed by long lines and cast nets at the lake. It is important to locate all the fishers operating in the lake and daily record of catches be collected for a more accurate picture of the total catch and fish species. Mesh size regulation prevent over exploitation of young fish, before they attain sexual maturity. It is recommended that the cost of procuring fishing inputs such as fishing gear and crafts and safety kits should be monitored by government and be subsidized for the fishers.Key words: drum trap, crafts, catch, exploitation, Oguta, mesh size, trap

Selectivity is a fishing gear characteristic capable of catching fish of a specific size and species from the existing population distribution. Mesh size is one of the important factors that influence gillnets’ selectivity, because different length-classes of fish are caught by them. This report focuses on the selectivity of two mesh sizes of gillnets (8.89 cm and 10.16 cm) on mackerel's catch and constructing a gillnet in Sungailiat waters. Experimental fishing methods and selectivity analysis were used for the fishing gear’s more selective preparation, if the largest fishing ratio's value at the fork length (L) is high and the standard deviation value (S) is closer to 1. It is concluded that to be more selective a largest S (L) value of 0.999267194 at fork length (L=54.95 cm), and with a larger value of S (L) 0.997096071 and with (L=66.55 cm) for mesh Sizes 8.89 cm and 10.16 cm, respectively.

Selection Parameters

We developed a new approach for directly quantifying selection parameters for fishing gear using a dual underwater video camera apparatus and employed the method to estimate gill net retention probability for walleye (Sander vitreus). The method allows observation of fish behavior around fishing gear and estimation of the absolute probability of fish encountering, contacting, or being retained by the gear. We demonstrated the applicability of this method by quantifying the probability that walleye were retained in multifilament nylon gill nets after contacting the nets. Walleye with total lengths 2.49 times the perimeter of the mesh were most likely to be retained, and retention probability peaked at 0.60 (95% confidence interval 0.41–0.90), meaning 40% of walleye that were the ideal size for a given mesh escaped after contacting the net. Our empirically derived retention curve exhibited a steep ascending limb and strong positive skew because of walleye morphology and the tendency for larger walleye to be captured by tangling. Most walleye that avoided capture did not fully enter the mesh or backed out of the mesh after they became temporarily wedged or tangled.

Main Construction

Fish distribution from Sibolga was caught using purse seine. This fishing gear is very popular among fishermen in Sibolga. The main construction with a mesh size < 1 inch is very beneficial for fishermen. The purpose of this report is to determine the types of purse seine operating at PPN Sibolga and to analyze the suitability of purse seine construction based on government policies. The methods used were interviews and observation. Data collection was done by measuring 5 samples. The result is that the type of purse seine that operates at PPN Sibolga consists of 2 types, namely auxis purse seine and tight purse seine. The length of the purse seine construction used is 500 meters with a mesh size of 20-30 mm, while based on KEPMEN KP number 71/2016, the length of the net of 300–600 m must have a mesh size of ≥ 1 inch. The mesh size used by Sibolga fishermen is smaller and does not comply with regulations. Other constructions are stated to be in accordance with the references listed.

Using Data

Fishing capacity is ability of fishery input (boat) used in output production (catch), it measured by using fishing unit or other fishing gear production. In simple way, fishing capacity is an ability of fishing boat (with all aspects) to capture fish. This ability will depend on the fish stock to be captured (seasonally or yearly) and the ability of the fishing gear itself. The aims of this research are to analyze technical efficiency and capacity of capture fishery in between years, of fishing gear and of purse seine. Research location was in the northern water of Gorontalo. Data was analyzed using data envelopment analysis (DEA). The development of capture fishery in 20 years since 1986 - 2005 of the northern water of Gorontalo showed that 1995, 2003 and 2005 are the most efficient years compared to other years, therefore, these years can be used as a basic of allocating fishing effort and catch. The most efficient fishing gear was purse seine and line, whereas gill net is an inefficient fishing gear. For purse seine, there are 11 boats that have efficiency value of 1. In order to reach efficiency level of each purse seine, it needs to decrease the number of input such as reducing 27.97 percent of boat, reducing the length of fishing duration to 29.49 percent,reducing the length of fishing trip / tonnage month to 26.87 percent and reducing fishing operation cost to 15.67 percent.
