Groupers are a valuable fishery resource of reef ecosystems and are among those species most vulnerable to fishing pressure because of life history characteristics including longevity, late sexual maturation and aggregation spawning. Despite their economic importance, few grouper fisheries are regularly monitored or managed at the species level, and many are reported to be undergoing declines. ...
The objective of this paper was to study angling from September, 2002 to September, 2004 in the Lobo-Broa Reservoir, Itirapina, SP (22 degrees 15' S and 47 degrees 49' W). Interviews (total 1,027) with sport fishers were accomplished in the three main fishing sites (Horto, Píer and Praia). This fishing was practiced with a simple fishing rod and reel, mainly in Horto, where the catches and fish...
Biodiverse coastal zones are often areas of intense fishing pressure due to the high relative density of fishing capacity in these nearshore regions. Although overcapacity is one of the central challenges to fisheries sustainability in coastal zones, accurate estimates of fishing pressure in coastal zones are limited, hampering the assessment of the direct and collateral impacts (e.g., habitat ...
The Agriculture, Forestry and Fishing sector comprises establishments primarily engaged in growing crops, raising animals, harvesting timber, and harvesting fish and other animals on a farm, ranch, or from their natural habitats (Executive Office of the President, 2002). About 2.1 million workers were employed in agriculture, forestry, and fishing in the United States in 2004, making it one of ...
BACKGROUND Scuba diving fishing, predominantly targeting sea cucumbers, has been documented to occur in an uncontrolled manner in the Western Indian Ocean and in other tropical regions. Although this type of fishing generally indicates a destructive activity, little attention has been directed towards this category of fishery, a major knowledge gap and barrier to management. METHODOLOGY AND P...
BACKGROUND NIOSH established its Alaska Field Station in Anchorage, Alaska, in 1991, after identifying Alaska as America's highest-risk state for traumatic worker fatalities. Since then, NIOSH established comprehensive occupational injury surveillance in Alaska, and formed and facilitated interagency working groups (of state and federal agencies) and industry, labor, and professional organizati...
Entanglement in fixed fishing gear affects whales worldwide. In the United States, deaths of North Atlantic right (Eubalaena glacialis) and humpback whales (Megaptera novaeangliae) have exceeded management limits for decades. We examined live and dead whales entangled in fishing gear along the U.S. East Coast and the Canadian Maritimes from 1994 to 2010. We recorded whale species, age, and inju...
The supervisory authorities insufficiently control the large-scale fishing that currently exists and there are problems in this industry. study of current real situation on mining vessels is very important, since data, they receive from them often incorrect actual volumes seizure aquatic biological resources unknown. Describes state problem irrational use example Pollock fishing. Provides data ...
Abstract Fishing operational data is the key to making fisheries management policies. Without this data, policymakers could only speculate on current field conditions; hence their decisions are not solutions issues and problems in even difficult implement. Currently, government encourages collection fishing operations through three schemes, namely results of fish unloading at ports, independent...
