Catch rates as indices of abundance of yellowfin tuna, Thunnus albacares, in the Eastern Pacific Ocean

ENGLISH: Catch and effort data from logbooks of tuna seiners were used to make estimates of catch per hour of searching for 1970-1980. The estimates were standardized using a regression model to make annual estimates of abundance adjusted for fishing mode, speed, capacity, use of aerial assistance, net dimensions, and sea-surface temperature. Inside the CYRA the standardized estimates for tuna schools associated with dolphins and those for schools not associated with dolphins showed a similar overall pattern of decline. The 1980 catch rates were about 300/0 of the 1970 rates, the decline being greater for the schools not associated with dolphins. Dolphin-associated schools outside the CYRA declined to about 60% of the 1970 levels. SPANISH: Se emplearon los datos de la captura y el esfuerzo de los cuadernos de bitácora de las embarcaciones cerqueras para hacer las estimaciones de la captura por hora de búsqueda correspondientes a 1970-1980. Se normalizaron estas estimaciones usando un modelo de regresión con el fin' de hacer las estimaciones anuales de la abundancia, ajustadas según la moda de pesca, velocidad, capacidad, uso de ayuda aérea, dimensiones de la red y temperatura de la superficie del mar. En el ARCAA las estimaciones normalizadas de los cardúmenes de atún asociados con delfines y aquellas de los cardúmenes no asociados con delfines, indicaron una pauta general similar de reducción. Las proporciones de captura de 1980, fueron cerca del 300/0 de las de 1970, encontrándose la mayor reducción en los cardúmenes no asociados con delfines. Los cardúmenes asociados con delfines, fuera del ARCAA, se redujeron en un 60% con respecto a los niveles de 1970. (PDF contains 79 pages.)

Salmon action plan consultation. River Lune - draft

In February 1996 "A Strategy for the Management of Salmon in England and Wales" was launched by the then National Rivers Authority. The strategy concentrates on four main objectives for the management of salmon fisheries in England and Wales. These are primarily aimed at securing the well being of the stock but in doing so will strive to improve catches and any associated economic returns to the fisheries: (i) Optimise the number of salmon returning to homewater fisheries. (ii) Maintain and improve the fitness and diversity of salmon stocks. , (iii) Optimise the total economic value of surplus stocks. (iv) Ensure necessary costs are met by beneficiaries. These four objectives will be addressed through local Salmon Action Plans (SAPs) which will be produced for each of the principle salmon rivers in England and Wales by the year 2001. Each plan will review the status of the stock and the fisheries on a particular river, seek to identify the main factors limiting performance, draw up and cost a list of options to address these, and, consult 0with local interest groups. This report is the draft version of the Salmon Action Plan for the River Lune.

Guidelines for the scoping and environmental assessment of water resources projects. The environment and water resources projects - Volume 1

The following brief is to ensure standard criteria and format are used for the scoping and environmental assessment of water resources projects leading to the production of an environmental report or Environmental Statement. This volume is one of a series giving guidance on water resources projects. The water resources projects will predominantly comprise drought orders and permits, time limited and permanent licences. Smaller projects, such as spray irrigation licences, will not require an environmental assessment. This document forms the basis for discussions between the Environment Agency North East Region, consultees and the applicant. The process aims to produce a thorough assessment. Each section addresses consecutive elements of the assessment process. Section 2 outlines the structure for a scoping document, section 3 outlines the structure for an Environmental Statement and section 4 gives guidance on the role of an Environmental Action Plan. Appendices 1 and 2 should be used in conjunction with the scoping process and cover a wide range of aspects. However, some projects may not require all of them to be included, whilst for others, the inclusion of additional factors may be appropriate.

River Gowy and Thornton Brook improvements. Environmental Action Plan March 2000

This is the River Gowy and Thornton Brook improvements: Environmental Action Plan report produced by the Environment Agency in 2000. This Environmental Action Plan relates to the proposals by the Environment Agency to improve the flood defences of land adjacent to the River Gowy, about 3 km east of Ellesmere Port, Cheshire. The purpose of the Environmental Action Plan (EAP) is to provide details of how the issues addressed in the Environmental Statement (ES) will be carried through to the completion of the project. The EAP represents a commitment to the environmental recommendations formulated during the environmental assessment process and should be closely adhered to during the design, construction and post project monitoring o f the works. For any matters that cannot be finalised until during construction the constraints will be detailed in the plan so they are implemented in the contracts.

Mapping the shallow-water coral ecosystems of the Freely Associated States: an implementation plan

This Freely Associated States Shallow-water Coral Ecosystem Mapping Implementation Plan (FAS MIP) presents a framework for the development of shallow-water (~0–40 m; 0–22 fm) benthic habitat and possibly bathymetric maps of critical areas of the Freely Associated States (FAS). The FAS is made up of three self-governing groups of islands and atolls—the Republic of Palau (Palau), the Federated States of Micronesia (FSM), and the Republic of the Marshall Islands (RMI)—that are affiliated with the United States through Compacts of Free Association. This MIP was developed with extensive input from colleges, national and state regulatory and management agencies, federal agencies, non-governmental organizations, and individuals involved in or supporting the conservation and management of the FAS’s coral ecosystems. A list of organizations and individuals that provided input to the development of this MIP is provided in Appendix 1. This MIP has been developed to complement the Coral Reef Mapping Implementation Plan (2nd Draft) released in 1999 by the U.S. Coral Reef Task Force’s Mapping and Information Synthesis Working Group. That plan focused on mapping United States and FAS shallow-water (then defined as <30 m) coral reefs by 2009, based on available funding and geographic priorities, using primarily visual interpretation of aerial photography and satellite imagery. This MIP focuses on mapping the shallow-water (now defined as 0–40 m, rather than 0–30 m) coral ecosystems of the FAS using a suite of technologies and map development procedures. Both this FAS MIP and the 1999 Coral Reef Mapping Implementation Plan (2nd Draft) support to goals of the National Action Plan to Conserve Coral Reefs (U.S. Coral Reef Task Force, 2000). This FAS MIP presents a framework for mapping the coral ecosystems of the FAS and should be considered an evolving document. As priorities change, funding opportunities arise, new data are collected, and new technologies become available, the information presented herein will change.

Community visioning and action plans: Tonle Sap hub

The process of rolling out the CGIAR Research Program on Aquatic Agricultural Systems (AAS) in 12 target villages in the Tonle Sap region in Cambodia throughout 2013 involved several important tasks at different stages. This report covers one of those tasks: the Community Life Competence Process (CLCP), commonly referred to by stakeholders as "visioning". It has two main objectives: (1) to document the community visioning process, including the development of a community action plan and NGO work plan to monitor progress; and (2) to document village and network profiles of key community stakeholders at the village level.
