The tuna fishery off northwestern Luzon: catch of purse seines and hand lines operating around fish-aggregating 'payaw'
Abstract
The tuna fishery along northwestern Luzon was studied from March 1994 to April 1995. About 120 units of fish aggregating ‘payaw’ were set 20–100 km offshore and fished by about 350 handline boats and 6 purse seines. The handline landing areas were in Apatot, San Esteban, Ilocos Sur and in Darigayos Cove, La Union. The resident purse seine was based at Poro Point in San Fernando, La Union; the others were occasional operators. Skipjack tuna Katsuwonus pelamis was the primary species landed by the purse seine and yellowfin tuna Thunnus albacares was mostly landed by the hand lines. These species occurred year-round with peaks during the dry season. The purse seine was operated about 9 sets per month, and landed an average of 51 mt fish monthly (catch rate 5.7 mt/set), highest in November, December and March. Handline fishing was carried out an average of 17 days a month (catch rate about 19 kg/boat-day). The tuna fishery was adversely affected by strong monsoon winds and typhoons. The rough seas inhibit fishing and give the tuna populations much needed respite from the intense fishing pressure.

Socioeconomic profile of tuna fishers in northwestern Luzon
- In TU Bagarinao (Ed.), Research Output of the Fisheries Sector Program, 2007 - Bureau of Agricultural Research, Department of AgricultureA study of tuna fishers in northwestern Luzon (Region I) was done by means of a questionnaire. The 511 respondents included 178 from Ilocos Sur, 200 from La Union, and 133 from Pangasinan. Most of them were younger than 50 years, had basic education, married with large families of 3-9 children, owned the houses they lived in, and had low annual incomes of about P35,000. Fishing was their sole means of livelihood for almost all the respondents, except some for whom farming supplemented the income from fishing. Majority worked every night or day, 36% went fishing every other night or day, and 13% went fishing five times a week. Most fishers went out to sea at night. Fully 52% of the fishers worked within 50 km from shore; 38% fished within 51–100 km, and the others went out farther than 100 km and even 200 km. La Union fishers worked closest to shore (average 38 km) and Pangasinan fishers the farthest (average 92 km). More than 90% of all fishers used motorized bancas, which made it possible for them to fish farther out to sea. Only 36% of the fishers owned the boats and fishing gears they used, and most did not. In all three provinces, the capital for the fishing enterprise came mainly from savings. The average cost of motorized boats was P31,200; non-motorized boats, P1,200. Longlining was the most preferred fishing method in the region. Hand lining was the second most preferred in Ilocos Sur and Pangasinan. Gillnetting and other methods (rabuk, kawil, pana, and bira-bira) were ranked third and fourth, and trawling was the least preferred. Drift gill nets used for tunas cost on average P680; tuna long lines, about P600; tuna hand lines, P345; and troll lines, P750. The main species caught by the fishers were skipjack tuna, yellowfin tuna, frigate tuna, Spanish mackerel, rainbow runner, dolphinfish, sailfish, blue marlin, and threadfins. In Ilocos Sur, most fishers reported catches of 11-20 kg in one trip, and a few fishers caught 50 kg. Spanish mackerel and sailfish gave the fishers better incomes than the other species. Fish catches and prices and fisher incomes in La Union were lower than in Ilocos Sur. Threadfins were more abundant in La Union. Fishers in Pangasinan did not catch sailfin, marlin, or threadfins, but caught higher volumes (20–60 kg/trip) of the other species. -

Stock assessment of christian crabs (Charybdis feriatus, Linnaeus, 1758) in San Miguel bay
- In MRR Romana-Eguia, FD Parado-Estepa, ND Salayo & MJH Lebata-Ramos (Eds.), Resource Enhancement and Sustainable Aquaculture Practices in Southeast Asia: Challenges in Responsible Production … International Workshop on Resource Enhancement and Sustainable Aquaculture Practices in Southeast Asia 2014 (RESA), 2015 - Aquaculture Department, Southeast Asian Fisheries Development CenterAssessment of the status of swimming crab fisheries in San Miguel Bay with focus on Christian or Crucifix crab, Charybdis feriatus, was undertaken from November 2011 to January 2013. An analytical length-based fish stock assessment was employed using the FISAT (version 1.2.2). A total of 7,679 length frequencies (3,612 C. feriatus and 4,067 Portunus pelagicus) were used in the analysis. About 15 and 14 percent gravid females were harvested monthly for both species that may contribute to recruitment overfishing. Population parameters showed exploitation rate (E) for P. pelagicus and C. feriatus exceeded the optimum exploitation (E0.5) implying excessive fishing effort and heavily exploited stocks. Size at maturity of C. feriatus and P. pelagicus in San Miguel Bay is 8.3 cm and 8.5 cm, respectively. Doable options for resources conservation and management strategies are proposed and supported by local government units (LGUs) including the Integrated Fisheries and Aquatic Resource Management Council. -

Fish catch and fisher incomes before and after installation of artificial reefs in Panguil Bay, northern Mindanao
- In TU Bagarinao (Ed.), Research Output of the Fisheries Sector Program, 2007 - Bureau of Agricultural Research, Department of AgricultureTwo artificial reef complexes (10 modules) were deployed in Panguil Bay in 1990. The effect of the ARs on the fish catch and fisher incomes was studied from March 1993 to April 1994 in Purok 3, 4, 6, and 7 in San Antonio, Ozamis City and in Poblacion 1 and 4 in Clarin, Misamis Occidental. Clarin‘s 40 full-time fisher respondents had 50 outrigger boats, all without engines, and used 181 fishing gears, 93% of them simple or multiple hand lines. San Antonio‘s 80 full-time fisher respondents had 87 non-motor boats and 44 motor boats and used 489 fishing gears, 86% of them bottom-set gill nets. The fishers worked an average of 19 days a month and four hours a day. The fishing grounds were mostly between 3 and 3.5 km from shore, and the gears were operated in waters about 50 m deep. Of about 17,000 kg of fish harvested in Clarin and San Antonio over one year, 33% came from bottom-set gill nets, 32% from bottom-set long lines, and 28% from multiple hand lines. The catch included a great variety of fishes, plus shrimps and cuttlefish; threadfins made up 13% of the total volume by weight, slipmouths 10%, and sardines 7%. The catch ranged from 2,382 kg valued at P75,862 in Purok 3 to 3,212 kg worth P97,303 in Poblacion 1, but in Purok 7, the catch was 2,965 kg worth P123,195. The average annual revenues of fishers was P24,191 in San Antonio and P11,472 in Clarin, corresponding to monthly earnings of P2,016 and P956, respectively. The revenues and net incomes were low, but the returns on investment were high (78–300%). The fishing boat, with or without engine and gas, was the major expense incurred by the fishers. Between 1989 and 1993–94, the volume of fish catch increased two-fold in San Antonio and four-fold in Clarin. The average annual income of fishers in the six villages increased by 10–60% after the ARs, and the average annual expenses also increased by 5–30%. In 1993-94, the computed return on investment was 105% in San Antonio and 274% in Clarin, higher than in 1989.
