Ex-situ conservation of the germplasm of aquatic organisms

This paper summarizes some of the major issues relating to ex-situ conservation of the germplasm of aquatic organisms and gives examples of some current activities and future possibilities.

Conservation and management of marine fishery resources of Kerala State, India

The highly productive fisheries of Kerala, India, are suffering from overexploitation. Use of unsuitable fishing gears that result in a high level of wasteful bycatch and destruction of egg bearing and juvenile fish should be controlled. This paper makes some suggestions for monitoring and conservation of the fisheries in Kerala.

Status and conservation of Reeves shad resources in China

An endangered fish species in China, Reeves shad (Tenualosa reversii), is finding hope of restoration and conservation in aquaculture and induced breeding efforts spearheaded by the Yangtze River Fisheries Management Commission. The history and sensitive traits of the Reeves shad are described featuring the species' life history, population dynamics and management of the Reeves shad resources.

The National Marine Fisheries Service Habitat Conservation Efforts in Louisiana, 1980 Through 1990

Data quantifying various aspects of the Corps of Engineers wetland regulatory program in Louisiana from 1980 through 1990 are presented. The National Marine Fisheries Service (NMFS) habitat conservation efforts for this time period are described and averages involved delineated. From 1980 through 1990, NMFS reviewed 14,259 public notices to dredge, fill, or impound wetlands in Louisiana and provided recommendations to the Corps on 962 projects which proposed to impact over 600,000 acres of tidally influenced wetlands. NMFS recommended that impacts to about 279,000 acres be avoided and that more than 150,000 acres of compensatory mitigation be provided. During this period, marsh management projects proposed impounding over 197,000 acres of wetlands. On a permit by permit basis, 43% of NMFS recommendations were accepted, 34% were partially accepted, and 23% were rejected.

National Marine Fisheries Service Habitat Conservation Efforts in the Southeastern United States for 1988

Dataq uantifying the area of habitat affected by Federal programs that regulate development in coastal zones of the southeastern United States are provided for 1988. The National Marine Fisheries Service (NMFS) made recommendations on 3,935 proposals requiring Federal permits or licenses to alter wetlands. A survey of 977 of these activities revealed that 359,876 acres of wetlands that support fishery resources under NMFS purview were proposed for some type of alteration or manipulation. Almost 95 percent of this acreage was for impounding andl/or manipulation of water levels in Louisiana marshes. The NMFS did not object to alteration of 173,284 acres and recommended the conservation of 186,592 acres. To offset habitat losses, 1,827 acres of mitigation were recommended by the NMFS or proposed by applicants and/or the Corps of Engineers (COE). From 1981 to 1988 the NMFS has provided in depth analyses on 8,385 projects proposing the alteration of at least 656,377 acres of wetlands. A follow-up survey on the disposition of 339 permits handled by the COE during 1988 revealed that the COE accepted NMFS recommendations on 68 percent. On a permit-by-permit basis, 13 percent of NMFS recommendations were partially accepted, 17 percent were completely rejected, and 2 percent were withdrawn. The permit requests tracked by the NMFS proposed the alteration of 2,674 acres of wetlands. The COE issued permits to alter 847 acres or 32 percent of the amount proposed.

The distribution, conservation, and larval food plant of Epiplema becki Hayes (Insecta: Lepidoptera: Uraniidae) on the Galapagos Islands

Two new populations and the host plant of the rarely encountered Galapagos endemic moth Epiplema becki were found on Isabela Island, on Wolf and Sierra Negra volcanoes, with a sighting on Darwin Volcano. The host plant is the native Duranta dombeyana (Verbenaceae). The habitats where all known specimens were collected were Scalesia forest with Duranta bushes. To ensure the conservation of E. becki, we recommend control of introduced species in its habitat. CDF Contribution Number 1010.

Chalk rivers: nature conservation and management

This is a handbook about Chalk Rivers Nature Conservation and Management from March 1999 by the Water Research Centre and commissioned by English Nature and the Environment Agency, primarly provides an objective basis for formulating conservation strategies for relevant Site of Special Scientific Interest (SSSIs) and Special Areas of Conservation (SACs). It was also seen as being applicable to chalk rivers more generally and has increasingly been regarded as important to the work of the Biodiversity Action Plan Steering Group on chalk rivers, which is led by the Environment Agency. This report contains information on characteristic wildlife communities, their habitat requirements and the ecological impact of activities that are relevant to the chalk river environment. It provides guidance on setting management objectives, options for mitigating impacts, and measures for the maintaining and enhancing the river channel, riparian and floodplain areas associated. The term `chalk river’ is used to describe watercourses dominated by groundwater discharge from chalk geology, including those that flow over a range of non-chalk surface geologies at various points along their length. England contains numerous examples of this river type, located in and downstream of areas of outcropping chalk in the south, East Anglia and up into Lincolnshire and Yorkshire. Indeed, England has the major part of the chalk river resource of Europe. A number of chalk rivers have been designated as Sites of Special Scientific Interest (SSSIs) and English Nature and Environment Agency work drawing up joint conservation strategies.

Meres and mosses conservation plan: Rostherne Mere

This is a report on the Conservation Plan for Rostherne Mere. The project primarly involved collating existing information from a variety of sources, supplemented by a limited amount of survey work commissioned for the project, including identification of the surface water catchment, water flows, and land use within the catchment. The section 1 outlines the physical situation of the Site of Special Scientific Interest (SSSI), its geological setting and hydrological regime. A summary of the ecological characteristics, conservation interest and objectives is provided in Section 2, and the issues affecting the site are identified in Section 3. . Operations and mechanisms for addressing the issues are suggested in Section 4, compiled from field visits, information held on file by English Nature and the Environment Agency, and English Nature. The last Section 5 provides a brief summary of the site’s condition and a discussion of the issues and operations suggested. A summary table is provided of the recommended actions for each site. Supporting information on the hydrology and aquatic ecology (where relevant) is provided in appendices.

The NRA's role in wetland conservation

This is the NRA's role in wetland conservation report produced by the National Rivers Authority in 1995. This document is the third of a series of three R&D Notes produced as part of an integrated research programme addressing aspects of the NRA's role in wetland management and conservation. Chapter 1 considers the nature of the wetland resource and its definition. Chapter 2 presents the NRA's current legislative and policy framework relating to its role in wetland conservation. National and international legislation and agreements are considered, and particular attention is afforded to the potential implications of the 'Habitats Directive'. Chapter 4 presents key examples of operational casework involving wetlands. Differences in approach and external perceptions of the NRA's current and likely future role in wetland conservation are discussed within Chapter 5. Other issues highlighted in this report are: policy guidance required on NRA’s role in land drainage; standard of flood defence service for wetlands; cost-benefit analysis; strategies for halting and reversing the decline and degradation of wetland resource; and Catchment Management Planning.
