The Global Positioning System (GPS) offers a very easy and a relatively cheap way of finding out ones location on the planet. As the name indicates this project is an application of GPS. It is a very hardship business for fishermen who stand in the middle of the ocean without knowing where they are actually located. This project addresses these problems by providing a preprogramed portable navi...
We measured plasma concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and polychlorinated biphenyls (PCBs) in fishermen from the Finnish Baltic Sea area and fishermen fishing in inland lakes. The concentrations clearly correlated with the frequency of fish meals and consumption of Baltic fatty fish. The body burden of PCDD/Fs reached the median level of 170 pg/g to...
Research on hygiene has been relatively limited in the current era of rigorous observational studies and clinical trials. We set out to investigate the perception and practices of genital hygiene among fishermen working on the beaches along Lake Victoria, targeted for a topical male microbicide hygiene intervention. We conducted 12 focus group discussions involving fishermen (n = 130), recordin...
Historically, fishermen targeted fish in shallow, nearshore waters relatively close to port (Pauly et al. 2005). As these species became depleted, to meet growing demands, fishermen were forced to move offshore and into deeper waters (Hutchings and Reynolds 2004; Koslow et al. 2000; Morato et al. 2006; Hilborn et al. 2003; Pauly et al. 2002, 2005). Steady advances in fishing technology facilita...
On the southwest Pacific Coast of Colombia, a field study was initiated to determine the human-vector association between Anopheles (Kerteszia) neivai and fishermen, including their nearby houses. Mosquitoes were collected over 24-h periods from mangrove swamps, marshlands and fishing vessels in three locations, as well as in and around the houses of fishermen. A total of 6,382 mosquitoes were ...
AIMS To establish the causes and circumstances of all deaths occurring at work or related to work among fishermen in British commercial fishing between 1976 and 1995. METHODS A retrospective study, based on official mortality files, with a population of 440 355 fishermen-years at risk. RESULTS Of 616 deaths in British fishing, 454 (74%) were due to accidents at work, and 394 (87%) of these ...
BACKGROUND The people residing in coastal areas of Visakhapatnam are mostly engaged in fishery, which is always been a physically demanding job, and numerous factors have direct or indirect impact on the health of fishermen; but, the data about their physical fitness or health status is quite scanty. Thus, the present study was conducted to assess their cardiorespiratory fitness pattern, as wel...
INTRODUCTION the fishing activity throughout the Upper Paraguay River Basin has huge financial and biological importance. This retrospective study investigated the occurrence of injuries caused by fish of the Pseudoplatystoma genus (spotted catfish or pintado and striped catfish or cachara) in professional fishermen of the Pantanal of Mato Grosso do Sul State. METHODS we collected information...
Understanding fishing fleet dynamics is important when using fishery dependent data to infer the status of fish stocks. We analyzed data from mandatory catch reports from the commercial lake trout (Salvelinus namaycush) fishery in Michigan waters of Lake Superior during 1929–1961, a period when lake trout populations collapsed through the combined effects of overfishing and sea lamprey (Petromy...
Activities of fishermen in the Bay of La Paz, B. C. S. are focused to satisfy the local demand of fish and shellfish by using approximately 300 small outboard crafts equipped with gillnets. Sea lions in this Bay attack the fishes captured damaging both product and gear. We did experimental gillnet throws to determine the frequency and preferences of sea lions in fishing areas. 52 experimental g...
