The Driftnet Fishery in the Fort Pierce-Port Salerno Area off Southeast Florida

From May through September 1987, observations were made on 38 trips in the driftnet fishery off the Fort Pierce-Port Salerno area off southeast Florida. Of the number and weight of fish landed on observed trips, 91.6 percent consisted of king mackerel, Scomberomorus cavalla, the targeted species. Over 33 species of fishes were observed among the discarded by-catch. The most frequently occurring species in the discards was little tunny, Euthynnus alletteratus, which made up 67.0 percent by number of the discarded by-catch. Total landings for all commercial gear from Saint Lucie and Martin counties (the counties of the study area) increased 516,741 pounds from 1986 to 1987. In 1986, 55 percent of the catch was from handline and 45 percent from driftnet landings. In 1987, 78 percent was from driftnet and 22 percent from handline landings. A comparison of lengths from recreational and commercial landings showed recreationally caught fish to be, on the average, smaller. No marine mammals, birds, or turtles were entangled in the net on observed trips. Data on cost of nets. fuel, and supplies plus the distribution of earnings among the crew were obtained for five driftnet boats.

Technical efficiency in artisanal fisheries (AF) in Badagry local government area of Lagos State, Nigeria

This study examined the technical efficiency in artisanal fisheries in Lagos State of Nigeria. The study employed a two stage random sampling procedure for the selection of 120 respondents. The analytical techniques involved descriptive statistics and estimation of technical efficiency following maximum likelihood estimation (MLE) procedure available in FRONTIER 4.1. The MLE result of the stochastic frontier production function showed that hired labour, cost of repair and capital items are critical factors that influences productivity of artisanal fishermen with the coefficient of hired labour being highly elastic. This implies that employing more labour will significantly increase the catch in the study area. The predicted farm efficiency with an average value of 0.92 showed that there is a marginal potential of about 8 percent to increase the catch, hence the income of the fishermen. The study further examined the factors that influence productivity of fishermen in the study area. Year of education, mode of operation and frequency of fishing have important implication on the technical efficiency of fishermen in the study area.

Northern Area Fisheries Advisory Committee 5th January, 1981

This is the report from the Northern Area Fisheries Advisory Committee meeting, which was held on the 5th January, 1981. It covers information on the review of fisheries byelaws, netting off Flimby Beach and the review of a net limitation order which was due to expire. It also includes the report by the area fisheries officer on fisheries activities which comments on river conditions and fishing for salmon, sea trout and brown trout, and the recorded numbers of fish which passed through Yearl Weir fish counter up to the 9th November. Also covered in the report is an update on Holmwrangle hatchery and the stocking numbers of salmon, sea trout and non migratory trout by the Water Authority. Finally the report adds about fish disease, biological work and the considerations of the River Caldew as a migratory fish river. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

This comments on river conditions and fishing and an update on Hollingworth and Pilot hatchery. Finally the report adds about fish mortalities, and lists of stockings carried out for non migratory trout and coarse fish by the North West Water Authority and Angling Associations which gives the size of the fish, the source from which they came from and the receiving water. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.
