Oyster Spatfall In Virginia Rivers: 1987 Annual Summary, James Whitcomb
Oyster Spatfall In Virginia Rivers: 1987 Annual Summary, James Whitcomb
Reports
The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made on oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells is counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur.
A Development Plan For The South Coast Inshore Trawl Fishery, Fisheries Department Of Western Australia
A Development Plan For The South Coast Inshore Trawl Fishery, Fisheries Department Of Western Australia
Fisheries management papers
In March 1986 discussions were commenced between officers of the Fisheries Department and the Australian Fisheries Service concerning management measures for trawl fishery in the Great Australian Bight. These measures were considered necessary as a Western Australian Company (Toskel Fishing Co.) had commenced fishing the area. Given the excess fishing capacity in other Australian trawl fisheries it was considered advisable to institute management at an early stage and control development of this deep water fishery. Concurrent with these developments, mainly directed towards the control of larger trawlers in deeper waters, several small Western Australian trawlers operating out of Esperance and …

Lake Mead Prefertilization Study: Preliminary Nutrient Enhancement Studies In Lake Mead, Richard P. Axler, Larry J. Paulson, Patrick J. Sollberger, Donald H. Baepler, U.S. Bureau Of Reclamation
Publications (WR)
Studies conducted by the University of Nevada-Las Vegas (UNLV), the Nevada Department of Wildlife (NDOW), the Arizona Game and Fish Department (AGFD), The Nevada Division of Environmental Protection (NDEP), and the United States Bureau of Reclamation (USBR) have identified decreased algal production as a major factor involved in the decline of the Lake Mead sport fishery. Phosphorus-laden silt particles in the Colorado River have been sedimenting out in Lake Powell since the completion of Glen Canyon Dam 286 miles upstream in 1963. This sharp decrease in phosphorus loading to Lake Mead (>5000 tons per year) has resulted in decreased …

Thermal Tolerances And Preferences Of Fishes Of The Virgin River System (Utah, Arizona, Nevada), James E. Deacon, Paul B. Schumann, Edward L. Stuenkel
Thermal Tolerances And Preferences Of Fishes Of The Virgin River System (Utah, Arizona, Nevada), James E. Deacon, Paul B. Schumann, Edward L. Stuenkel
Publications (WR)
Critical thermal maxima (CTM) and thermal preferenda of the common fishes of the Virgin River were examined. Differences in final temperature preferenda and CTM for species with low thermal lability (speckled dace, spinedace, roundtail chub) correspond well with differences in their distribution and abundance in the river. These species shifted their acute thermal preferences relatively little as acclimation temperature increased. For thermally labile species (woundfin, red shiner, desert sucker, and fiannehnouth sucker), the final preferendum is a less precise indicator of probable distribution. The woundfin, an endangered fish, has a high CTM (39.5 C at 25 C acclimation) and a …

Report Of The Rock Lobster Industry Advisory Committee To The Hon. Minister For Fisheries., Rock Lobster Industry Advisory Committee
Fisheries management papers
The Committee recognises that the exploitation rate on the rock lobster stocks is very high and that this factor is a major importance in formulating the advice on management measures. However, the Committee also recognises the high level of capital investment in the industry and that any recommendation which leads to a significant change in the management rules is likely to have a far reaching effect on many of the participants. Accordingly, the Committee endeavours to reduce to a minimum the year to year changes in the management rules. When changes are required the Committee places considerable weight on matters …

Publications (WR)
The objectives of this study were to:
1. Establish baseline densities of benthic invertebrates and relative abundance of crayfish in Lake Mead.
2. Evaluate the distributions of benthic organisms and crayfish in relation to existing habitat conditions and 1imnological characteristics of Lake Mead.
3. Measure seasonal changes in abundances of benthic organisms and crayfish in Lake Mead.
4. Compare observations of Procambarus clarkii life history in Lake Mead to reports from other aquatic systems.
5. Evaluate the importance of benthic organisms and crayfish as food sources for game fish in Lake Mead.
The Shark Bay Scallop Fishery: Discussion Paper, L. M. Joll
The Shark Bay Scallop Fishery: Discussion Paper, L. M. Joll
Fisheries management papers
Studies of the biology of the saucer scallop Amusium balloti in Shark Bay show that it is a highly fecund, broadcast spawner, with a long breeding season (from April to December). It is also a fast growing species, with the bulk of the recruits from a breeding season reasing fishable size by April/May of the next year, at which time they also enter their first breeding season. In recent years, however, the earlier part of the breeding season appears to have been the most important for production of recruits.
Analysis Of The Water-Quality Standards Proposed By The Nevada Division Of Environmental Protection, City Of Las Vegas, Nevada
Analysis Of The Water-Quality Standards Proposed By The Nevada Division Of Environmental Protection, City Of Las Vegas, Nevada
Publications (WR)
The Nevada Division of Environmental Protection (DEP) has proposed water-quality standards, applicable to Las Vegas Bay and Lake Mead, for (1) chlorophyll, (2) un-ionized ammonia, and (3) pH.
We have concluded that the proposed standards are unlikely to protect or improve water quality in Lake Mead. The proposed chlorophyll standard:
May harm the fishery. Lakes with more chlorophyll have greater fish production.
Will not improve clarity. Chlorophyll concentrations above 30 ug/1 have little effect on clarity.
Will not protect against scums or dominance by blue-green algae. Lake Mead shows no consistent relationship between chlorophyll and scums or blue-green dominance.
Will …

Further Options For Management Of The Shark Bay Snapper Fishery : Discussion Paper., P. Millington
Fisheries management papers
A limited entry fishing regime for snapper was introduced in Shark Bay in order to constrain growth in fishing effort. Additional measures were introduced to reduce the number of vessels in the fishery, control areas fished and limit permitted fishing gear, with the ultimate objective of reducing catches from traditional fishing areas to long term sustainable levels.

Publications (WR)
Ninety-three wildlife agencies were surveyed for information on their attempts to improve fish habitat. In addition, an annotated bibliography including over 100 summaries was completed on:
1. largemouth bass cover requirements and preferences,
2. use and effectiveness of artificial cover,
3. aquatic plant introduction and species requirements for germination and establishment,
4. terrestrial plant introduction and species requirements for germination and establishment, and
5. nutrient exchange between sediment, aquatic plants, and water.
A reconnaissance of existing terrestrial and aquatic vegetation was completed in June 1986 including the production of a video tape of the Nevada shoreline of Lake Mead.

This report is an update of a study made in June to mid-august 1979. This study was made by the Virginia Institute of Marine Science of the College of William and Mary for the Department of Highways and Transportation, Suffolk, Virginia. The previous study provided: 1) a description of the shellfish resource prior to construction of a new bridge; 2) an estimate of the value of the oysters and shell on leased areas within the right-of-way; and 3) a basis for a later study after construction to evaluate possible environmental changes.
Since 1979 the Commonwealth has purchased the right-of-way and …
