Could the Tristan powerboat CPUE decline have been caused by overfishing?
From 2006 to 2014 the CPUE from the powerboats at Tristan has dropped by about 75%, suggesting that exploitable biomass fell by a similar proportion.The Tristan assessment (Johnston and Butterworth 2015) interprets this primarily as the downside of a decline as a result of the very strong 1997 year class passing through and then out of the fishery ...

Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...

Abstract Introduction Novel ecosystems, where environmental conditions have been fundamentally altered from a historic norm, require nontraditional approaches to restoration. Suisun Marsh, located within California's San Francisco Estuary (SFE), is a novel, brackish water wetland complex, where managers have begun restoring tidal connectivity to ...

ABSTRACT Assessing fish diversity and abundance is crucial for effective marine conservation and management strategies, particularly in ecologically sensitive areas such as the North Sea. Bottom trawling, one of the most commonly used fishing methods, is facing growing criticism, even for scientific purposes, and has already been banned in ecologically

Multiple environmental DNA (eDNA) methods were compared with each other and with fyke netting for detecting invasive brown bullhead catfish. eDNA sampling combined with catfish‐specific metabarcoding provides sensitive detection and effectively complements traditional netting for biosecurity.

Horse Mackerel commercial CPUE and survey data series
This document describes the different fishing sectors for Horse Mackerel. It then summarises the commercial CPUE as well as the available survey data series. Maps are provided to show where fishing occurs and where survey data are from.

ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have

Efficiency of fishing gears in the river Halda, Chittagong, Bangladesh
To determine the catch efficiency of fishing gears, catch per unit effort (CPUE) data were collected for two years during January 2007 to December 2008 from the river Halda.
