Performance of Lacustrine Protected Areas (LPAs) on Lake Victoria: A Case of Bulago, Uganda

Aquaculture, Fish and Fisheries
The Bulago Lucustrine Protected Area (LPA) was established on Lake Victoria, Uganda, as a sanctuary for severely depleted fish stocks, a breeding and spawning ground and a biodiversity conservation zone. Despite its ecological importance, no studies have

Catch-per-unit-effort: which estimator is best?

Brazilian Journal of Biology
In this paper we examine the accuracy and precision of three indices of catch-per-unit-effort (CPUE). We carried out simulations, generating catch data according to six probability distributions (normal, Poisson, lognormal, gamma, delta and negative ...

Catch per unit of effort (CPUE) variation and sustainability of artisanal fishing in relation to environmental variables in Colombian Pacific

, 2023
Contextualization: artisanal fishing in the Colombian Pacific is positioned as one of the main sources of income for the communities settled on the coasts, therefore, there is strong pressure on fishing resources, with non-selective fishing gear such as the trammel netting and the hand linehook, capturing individuals that have not presented ...

Resource use by threatened, native Bull Trout (Salvelinus confluentus) in the presence of two non‐native salmonids

Journal of Fish Biology, EarlyView.
Abstract Introduction of non‐native species contributes to the global decline of freshwater fishes by disrupting the diet and resources of native species through competition. Despite the potential for non‐native trout (Family: Salmonidae) to compete with native trout, non‐native trout species have been widely introduced worldwide to support ...

Fish assemblage at a newly restored tidal wetland reflects surrounding waterways in the Sacramento‐San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction We studied the response of fish assemblages, water quality, and plankton following the completion of 700 acres of a 1184‐acre tidal restoration project (Dutch Slough Tidal Restoration; DSTR) in a system degraded by water diversions, channelization, non‐native species, and wetland loss.

Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Investigating the efficacy of tidal wetland restoration in enhancing aquatic food web resources for native fishes

Restoration Ecology, EarlyView.
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 ...

Silverside gold mine? Restored tidal habitats host abundant invasive fishes in a novel California marsh (U.S.A.)

Restoration Ecology, EarlyView.
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 ...

Seabird bycatch in Portuguese mainland coastal fisheries: An assessment through on-board observations and fishermen interviews

Global Ecology and Conservation, 2015
Competition with fisheries and incidental capture in fishing gear are the major current threats for seabirds at sea. Fishing is a traditional activity in Portugal and is mainly composed of a great number of small vessels.

Spatial and Temporal Variation of Catch per Unit Effort (CPUE) in Small-Scale Fisheries Along the Turkish Coast

Turkish Journal of Maritime and Marine Sciences
Fishery-dependent catch per unit effort (CPUE) values are an important indicator for assessing stock abundance due to the high cost of fishery-independent research. In this study, it was aimed to determine the spatial (Black Sea, Sea of Marmara, Aegean Sea and Mediterranean Sea) and temporal (2016-2022) changes in the fishing effort and CPUE values of ...
