Fisheries and Limnological Studies on West Point Reservoir, Alabama-Georgia

Book Description
West Point Reservoir on Chattahoochee River was impounded by a Corps of Engineers dam located 3.2 miles north of West Point, Georgia. Fishery and limnological studies funded by the Corps began in February 1976 to (a) document changes in the physical, chemical, and biological characteristics of West Point Reservoir over a period of years with emphasis on detection of those factors contributing to the expected decline in sport fishing success, and (b) implement and evaluate fishery management practices aimed at improving the catch per unit of effort of sport fisherman. The lake waters were very soft and maintained a pH near 7.0. Water inflow provided a hydraulic retention time varying from 30 to 83 days. There was adequate nutrient loading to produce eutrophic conditions though the availability of carbon is believed to be a factor limiting the eutrophic potential of this lake. Water quality and biological data gathered during this study indicated that West Point was a mesoeutrophic lake that produced sufficient fish foods to support a relatively high fish biomass (350 kg/ha). An interpretation of water quality data as it relates to sport fish production indicated that West Point Lake maintained favorable environmental conditions to sustain aquatic life during the course of the study (January 1976-September 1977).

Fisheries and Limnological Studies on West Point Reservoir, Alabama-Georgia. Phase V.

Pages : 161
Book Description
West Point Reservoir on the Chattahoochee River was impounded by a dam located 3.2 miles north of West Point, GA. Fishery and limnological studies began in Feb. 1976 to (a) document changes in the physical, chemical, and biological characteristics of West Point Lake over a period of years with emphasis on detection of those factors contributing to the expected decline in sport fishing success; and (b) implement and evaluate fishery management practices aimed at improving the catch per unit of effort of sport fisherman. Limnological data collected between Oct 80 and Sep 81 indicate that mean phytoplankton standing crops were higher this year than 1979-1980. The higher standing crops resulted from increases in all three major algae divisions; Chrysophyta, Chlorophyta and Cyanophyta. The increase in phytoplankton density should have a positive effect on the fishery since many of the fishes are plankton feeders. As for 1979-1980, mean total organic carbon levels varied little throughout the lake. The annual mean of 7.79 mg/l for the current year was higher than that reported for the previous four years. The mean of the quarterly samples of zooplankton was lower than any previous year which continued an apparent trend toward an overall decrease in zooplankton density in the lake. Harvest estimates on important sport fishes such as bass and sunfish show a decline.

Economic Valuation of Water Resources in Agriculture
Author: R. Kerry Turner
Publisher: Food & Agriculture Org.
ISBN: 9789251051900
Category : Business & Economics
Languages : en
Pages : 208
Book Description
The purpose of this report is to produce a review on water resource valuation issues and techniques specifically for the appraisal and negotiation of raw (as opposed to bulk or retail) water resource allocation for agricultural development projects. The review considers raw water in naturally occurring watercourses, lakes, wetlands, soil and aquifers, taking an ecosystem function perspective at a catchment scale, and takes account of the demands from irrigated and rainfed agriculture. It is hoped that the review will have particular application to developing countries where agreed methods for reconciling competing uses are often absent, but nevertheless takes account of valuation approaches that have been made in post industrial economies.

Centrarchid Fishes
Author: Steven Cooke
Publisher: John Wiley & Sons
ISBN: 9781444316049
Category : Technology & Engineering
Languages : en
Pages : 560
Book Description
Centrarchid fishes, also known as freshwater sunfishes, include such prominent species as the Largemouth Bass, Smallmouth Bass and Bluegill. They are endemic to Eastern North America where they form part of a multi-million dollar sports fishing industry, but they have also been widely introduced around the globe by recreational anglers, in aquaculture programs and by government fisheries agencies. Centrarchid Fishes provides comprehensive coverage of all major aspects of this ecologically and commercially important group of fishes. Coverage includes diversity, ecomorphology, phylogeny and genetics, hybridization, reproduction, early life history and recruitment, feeding and growth, ecology, migrations, bioenergetics, physiology, diseases, aquaculture, fisheries management and conservation. Chapters have been written by well-known and respected scientists and the whole has been drawn together by Professors Cooke and Philipp, themselves extremely well respected in the area of fisheries management and conservation. Centrarchid Fishes is an essential purchase for all fish biologists, ecologists, fisheries managers and fish farm personnel who work with centrarchid species across the globe.
