On the standardization of the fishing effort
(Instituto Nacional de Pesquisas da Amazônia, 2000-03-01)
In this note we demonstrate that the use of an index to standardize the fishing effort using the cpue of a standard vessel or gear is mistaken, once the cpues- catch per unit of total effort after standardization is similar ...
Artisanal fisheries in urban reservoirs: a case study from Brazil (Billings Reservoir, Sao Paulo Metropolitan Region)
(Blackwell Science LtdOxfordInglaterra, 2000)
How does host ecology influence sampling effort in parasite diversity estimates? A case study using Neotropical freshwater fishes
(Walter De Gruyter Gmbh, 2017-06-01)
Accurately estimating biodiversity is fundamental to ecological understanding and prediction. Helminthes are often neglected in biodiversity estimates and when included are often underestimated. Here we examine how sampling ...
Fish ladders select fish traits on migration - still a growing problem for natural fish populations
(Taylor & Francis Ltd, 2009-01-01)
We investigated the potential selective effect of fish ladders on physiological and morphological profiles of the curimbata, Prochilodus lineatus, during reproductive migration in Brazil. We registered sex, body weight and ...

Challenges in Assessing Fish Welfare
(Inst Laboratory Animal Research, Natl Res Council, 2009-01-01)
Descriptions of feeling states in nonhuman animals have relied on indirect evidence from empirical data. Assumptions that fish do not experience suffering lack evidence and in fact contradict a large body of indirect ...

Monitoring the fishing process in the sea urchin diving fishery of Galicia
(Oxford University Press, 2013-01)
The assessment and management of small-scale benthic fisheries requires attention to the spatial structure of stocks and patterns of effort allocation. Spatial information helps in the interpretation of fisheries data, and ...
