R.R的金枪鱼渔民社会经济剖面。LEDDA,N.L.Bagarinao,Teodora,U.通过调查问卷完成了吕宋岛(地区I)的金枪鱼渔民。511名受访者包括178名从Ilocos Sur,200来自La Union,133名来自Pangasinan。他们中的大多数年龄小于50岁,有基本的教育,已婚与3-9名儿童的大家庭,拥有他们住在的房屋,年度收入低约P35,000。钓鱼是他们几乎所有受访者的唯一的生计手段,除了一些农业为捕鱼收入的一些人。大多数每晚都在工作,每天36%钓鱼每隔一天或一天​​钓鱼,每周13%钓鱼五次。大多数渔民晚上出去海洋。完全52%的渔民距离岸边有不到50公里;38%钓鱼在51-100公里范围内,而其他人则超过100公里甚至200公里。La Union Fishers最靠近岸边(平均38公里)和Pangasinan Fishers最远(平均92公里)。 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. 2007-01-01T00:00:00Z 使用豆粕和米糠在制定的饮食中的石榴肾上腺素 Marasigan,Evelyn T.

Protein utilization was best among the fish fed the test diet D12.5. This study showed that soybean meal and rice bran at 4:1 ratio can be included in formulated diets for grouper to replace 12.5% to 25% of the animal protein sources. However, the results for the test diets may also have been due to other factors - the high fish meal content, inclusion of mussel meal, and increase in cod liver oil. 2007-01-01T00:00:00Z 沉淀和海藻和贻贝生物滤膜治疗虾塘流出物 堡垒,诺玛R.

B.Bagarinao, Teodora A total of 2,643 kg of groupers were collected from six markets (96% of the biomass) and from prescribed fish traps in three fishing grounds (106 kg, 4%) around Zamboanga City and Basilan from November 1993 to October 1994. The collection included 26 species in seven genera: Aethaloperca, Cephalopholis, Cromileptis, Epinephelus, Niphon, Plectropomus, and Variola. The three species of highest biomass were Epinephelus fasciatus (26%), Cephalopholis sonnerati (14%) and Cromileptis altivelis (13%). The least biomass was contributed by Epinephelus sexfasciatus (0.1%), Plectropomus areolatus (0.1%), and Cephalopholis sexmaculatus (0.3%). Grouper biomass was lower from November to April and greater from May to October. Groupers caught by the prescribed fish traps were mostly Epinephelus merra (50% of the total). The highest catch of grouper was 0.8 kg/fish trap around Sta. Cruz Island in July, and the highest catch of all demersal fishes was 7 kg/trap around Malamawi Island in September. On average, groupers made up less than 10% of the monthly catch of fish traps. The groupers collected from the markets and from the fish traps averaged 28 cm in total length— all young juveniles. Cromileptes altivelis (average 38 cm) were the largest individuals and Plectropomus spp. (36 cm) similarly so. The largest C. altivelis (1.5 kg) was caught in December and the smallest (0.8 kg) in April and August. The various Cephalopholis species averaged 31 cm, and the various Epinephelus species were smallest at 26 cm. Groupers were largest in December and smallest between January and May. Length-weight equations were derived for seven grouper species. Of the 78 grouper stomachs that were dissected, 52 were empty and 26 contained food, mainly crabs, anchovies, hermit crabs, soldierfish, squids, and shrimps. Groupers with mature and ripe varies had from 3,000 to 11,000 eggs per gram ovary. 2007-01-01T00:00:00Z
