| The purpose of this study was to estimate the economic effects of hunting and fishing activities during the 2001-2002 season on the North Dakota economy, and to compare current information to previous studies to identify trends in hunting and angling activities. A mail survey of 29,034 resident hunters and anglers and 7,199 nonresident hunters and anglers was conducted to solicit information on 21 hunting and fishing activities during the 2001-2002 season. Total spending by hunters and anglers in North Dakota during the 2001-2002 season was estimated at $468.5 million, excluding purchases of licenses. Resident hunter and angler expenditures were estimated at $402.7 million, and nonresident hunter and angler expenditures were estimated at $65.9... |

| Macro-economic forces, technological innovations in equipment, abundant wildlife populations, changing participation levels, and land access are all contributing to a changing environment for wildlife managers and outdoor recreationists. Since the late 1970s, numerous studies have periodically examined hunter and angler spending in North Dakota; however, comprehensive assessments of changes in spending over time have not been conducted. The purpose of this report was to evaluate changes in hunter and angler spending from 1981 through 2001 and evaluate spending patterns based on selected participant characteristics. For resident hunters, increasing trends in miles traveled, spending on lodging, and spending on durable goods were observed, while overall... |

| The effects of "localized depletion" of a pelagic fishery (herring) on a non-extractive marine activity (tourism) are investigated. Proponents of the localized depletion theory claim that intense fishing effort can lead to areas that are unsuitable for predators like tuna, groundfish, and whales. This leads to poor outcomes for the fishing and whale-watching industries. However, there has been no consensus in the scientific community about the existence of this phenomenon. Localized depletion would be consistent with an economic theory of joint production, in which nearshore herring stocks are an input in production of both herring and whale-watching trips. A unique dataset of daily whale-watching outcomes is combined with fishing effort and oceanographic... |

| No litoral brasileiro, a legislação costuma regular as práticas pesqueiras segundo o ciclo de vida das espécies-alvo, mas o fato deste não ser coincidente entre as espécies dominantes nas capturas dificulta o manejo em pescarias multiespecíficas. No litoral de Santa Catarina, o defeso aplica-se apenas à pesca de arrasto, e para tal considera o período reprodutivo do camarão sete-barbas, Xyphopenaeus kroyeri. O presente trabalho investiga a incidência da atividade pesqueira sobre indivíduos em reprodução da betara preta, Menticirrhus americanus, espécie comercialmente apreciada e frequente nas pescarias. As amostragens ocorreram em 2006 e 2007, em desembarques do município de Itapoá, norte do Estado (26°00’S; 48°36’W). Calcularam-se os valores de proporção... |

| Tuna are highly prized in Oriental cuisine, and the bigeye tuna (Thunnus obesus) is of great commercial importance. Quality is assessed by the tuna meat quality, freshness, texture and fat, which can be altered by factors inherent to capture, such as days of onboard storage, months of the year, whether the catch was living or dead, fish weight and year. These factors were correlated to identify those that affect quality. We obtained data from nine vessels, from January 2007 to April 2010, creating an information bank of 21,908 bigeye tuna. Fish quality and parameters were related using multiple linear regression analysis, in which the variables were included in the model by a stepwise procedure (F>4). We found that live catch, heavier fish and fewer... |

| The current study investigated the ethnoecological knowledge developed by fishermen through their fishing activities and searched for ways to match such knowledge to empirical data available in the scientific literature. The research involved fishermen from three coastal lagoons in the northern region of the State of Rio de Janeiro, Brazil, who were consulted through semi-structured interviews after the establishment of a trustful relationship over a period of three years with the interviewer. Their knowledge, in addition to its cultural and historical importance to these populations’ survival, in many ways matches scientific studies based on an ethnoecological approach. Their knowledge considers reproductive aspects, feeding habits, and migratory fishing... |
