TLDR
From all scenarios tested, only those that significantly reduce the high effort of the recreational fishing would allow the recovery of the most exploited stocks in the marine ecosystem in the short and medium-term.Abstract:
In this paper we consider what may happen to the marine ecosystem of Gran Canaria Island within the 2030 horizon, if fishing strategies different from those currently in place were implemented and we evaluate the effect of, for example, reduction of recreational-artisanal fishing, limitation of catches (e.g. total allowable catches, TAC), or spatial distribution of fishing sectors. From all scenarios tested, only those that significantly reduce the high effort of the recreational fishing would allow the recovery of the most exploited stocks in the marine ecosystem in the short and medium-term. Moreover, the best management strategy, in contribution to abundance, was obtained with a scenario that has a spatial partition of exploitation rights between artisanal and recreational fishermen and includes no-fishing zones (NTZ). This work is a first attempt to use spatial and temporal models to assess the effectiveness of alternative fishery policies in the Canary Islands.read more

Simulating trophic impacts of fishing scenarios on two oceanic islands using Ecopath with Ecosim.
TL;DR: In this paper, the authors evaluated the impact of fishing, both professional and recreational, on the marine ecosystem, as well as the spatial evolution of the fishing effort in a projection period going from 2021 to 2030, that can be applied in decision-making and planning in the short and medium term.

First assessment of the spearfishing impact in the Canary Islands
David Jiménez-Alvarado,Airam Guerra-Marrero,Airam Sarmiento-Lezcano,Eva K. M. Meyers,José J. Castro +4 more
TL;DR: An onsite survey was conducted between June and December 2017 to characterize recreational spearfishing in the Canary Islands as discussed by the authors, where the majority of the fishermen estimate that 78.3% of the fishing areas that they visit are moderately degraded or highly degraded and that fishing resources have decreased by 25% to 60% or more since they began to participate in this activity.

The Impact of United States Recreational Fisheries on Marine Fish Populations
TL;DR: Recreational landings affect many of the most-valued overfished species—including red drum, bocaccio, and red snapper—all of which are taken primarily in the recreational fishery.

Ecospace: Prediction of Mesoscale Spatial Patterns in Trophic Relationships of Exploited Ecosystems, with Emphasis on the Impacts of Marine Protected Areas
TL;DR: The work in this paper presents a spatially explicit model for policy evaluation that allows for considering the impact of MPAs in an ecosystem (that is, trophic) context, and relies on the Ecopath mass-balance approach for most of its parameterization.

Effort distribution and catch patterns adjacent to temperate MPAs
TL;DR: Spatial resolution of traditional data sources was too crude to discern detailed MPA-related effects, as revealed by high-resolution vessel positions from VMS and catch data obtained by observers.
