چکیده

The European eel Regulation EC 1100/2007 establishes measures to recover the European eel stock. The Regulation requires Member States to guarantee a spawner escapement 40% of pristine levels by reducing eel mortality. The complexity and plasticity of eel life history make it difficult to assess the effectiveness of alternative management options, and tools allowing decision makers and fishermen to quickly assess the effectiveness of proposed management scenarios are urgently needed. We used stateof-the-art knowledge to develop a user-friendly simulation software allowing users to evaluate if current management policies meet the conservation target and evaluate the expected performances (spawner escapement and fishing yield) of alternative management scenarios. The software relies upon a demographic model explicitly accounting for the most relevant features of eel demography and has default settings for specific geographical areas and water systems. We demonstrate the software by exploring a variety of management plans in three European water systems. © 2014 Elsevier Ltd. All rights reserved.

Multi-objective assessment of conservation measures for the European eel (Anguilla anguilla): an application to the Camargue lagoons

The European eel (Anguilla anguilla) stock has declined since the early 1970s and is currently considered to be outside safe biological limits. The European Commission has proposed a regulation (COM 2005/472 final) to establish measures for the recovery of the stock, with the aim of achieving an escapement to the sea of 40% of the adult eel biomass (with respect to undisturbed conditions) from ...

A free user friendly program for evaluation of radiotherapy plans based on different dose response models

Introduction: Radiotherapy (RT) plan evaluation using dose response models has become a feasible approach in routine clinical practice. Although there are several tools for this task, they suffer from limitations including number of different dose response models and parameters. In the present study, we aimed to develop a free program for RT plan evaluation based on a variety ...

Fish Larvae Assembelge in the Northwestern Coast of the Persian Gulf: Khure Mussa Channel

Ichthyoplankton data provide a base for research into population dynamics of major fishery species. Information on ichthyoplankton ecology forms an important component of stock assessment and fishery management plans. Also, nursery areas are important regions for the recruitment success of fishery stocks and as such, conservation of these areas is a key part of fishery management. Temporal dist...

Designing Marine Reserves for Fishery Management

R reports have raised serious concerns about the rapid declines of historically productive marine fishery resources and the degradation of essential fish habitats. This global crisis has spurred development of innovative management strategies to rebuild depleted fisheries and marine ecosystems. One highly touted strategy involves the design and creation of marine reserves (areas off limits to e...
