Substituting Otoliths For Chemical Analyses: Does Sagitta = Lapillus?, Nathan G. Smith, Cynthia M. Jones

OES Faculty Publications

Chemical analysis of fish otoliths has become an important technique in fisheries science with widespread applications. Most research up to this point has focused predominantly on sagittal otoliths, but the underlying assumptions may also apply to lapilli. The goal of this study was to determine whether lapilli and sagittae have the same otolith chemistry and whether one can be substituted for the other for solution-based chemical analysis in wild-captured fish. We compared the stable isotope chemistry (δ13C and δ18O) of paired sagittae and lapilli of juvenile spotted seatrout Cynoscion nebulosus collected from Chesapeake Bay seagrass beds in 2002. …

Characterization Of 35 Microsatellite Loci In The Pacific Lion-Paw Scallop (Nodipecten Subnodosus) And Their Cross-Species Amplification In Four Other Scallops Of The Pectinidae Family, Ana M. Ibarra, Jessica Lynn Petersen, Thomas R. Famula, Bernie May

Department of Animal Science: Faculty Publications

Four microsatellite-enriched DNA libraries yielded 35 microsatellite loci from 100 primer pairs designed for Pacific lion-paw scallop, Nodipecten subnodosus. The number of alleles ranged from four to 28. Three of the 35 loci were not in Hardy–Weinberg equilibrium and linkage disequilibrium was found for one pair of loci. These microsatellites will be used to analyze the population structure of the species in Mexico’s Baja Peninsula to propose management strategies for scallop aquaculture development. Twenty-six primer pairs cross-amplified in Nodipecten nodosus, whereas none (Argopecten ventricosus) or few cross-amplified in the Argopecten species.

Molecular Population Genetics Of The Atlantic Sand Fiddler Crab, Uca Pugilator, Along The Atlantic Coast, David A. Weese

College of Graduate Studies: Theses & Dissertations

Author's abstract: The Atlantic sand fiddler crab, Uca pugilator, is an extremely abundant fiddler crab found along the eastern and Gulf coast of the United States. Fiddler crabs have a life cycle with an obligatory planktonic larval phase of 30-90 days, which might be expected to lead to widespread larval dispersal and consequent genetic homogeneity over considerable distances. However a large amount of morphological and behavioral variation is found between northern and southern populations along the eastern coast. This study was undertaken to determine the population genetic structure of U. pugilator and to determine whether these differences may have a …

Fisheries Research Report No. 152 - Development Of A Dna Database For Compliance And Management Of Western Australian Sharks., Rory Mcauley, K. Ho, R. Thomas

Fisheries Research Reports

Final FRDC Report - Project 2003/067

The capability to identify individual shark species from processed body parts is necessary for the WA Department of Fisheries to ensure the compliance of all WA fisheries with both existing protected species regulations and proposed new management measures for commercially important shark species. This project established a reference database of genetic profiles or ‘fingerprints’ for nine of Western Australia’s protected and commercially important shark species. Fingerprints from a 10th species, the shortfin mako (Isurus oxyrinchus) could not be obtained due to probable primer sequence mismatching. The database, in conjunction with an associated inspection and …

In this submission to the Integrated Fisheries Allocation Advisory Committee (IFAAC), the Department will outline what it believes are the most practical and cost effective ways of managing a system for allocating the abalone resource between the commercial, customary and recreational sectors.

In preparing this submission, it has been noted that because of the limited data on recreational catch outside of the metropolitan area, the Sustainable Harvest Limit (SHL) set for the fishery relates only to the area that is equivalent to Area 7 of the commercial fishery. Further, it is acknowledged that the Minister has approved that proportional catch …

Maximum Size Of Fish Caught With Standard Gears And Recreational Angling, Kevin L. Pope, Gene R. Wilde, Daryl L. Bauer

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We correlated maximum lengths of freshwater fishes captured during 10 years with standard gears (i.e., gill nets, boat electrofishers and trap nets) and angling from Nebraska water bodies to determine which methodology provided better estimates of maximum size of fishes produced within a given water body. In general, maximum length of fishes captured with standard gears was smaller than maximum length of fishes captured with angling. Although significant (based on sequential Bonferroni adjustment) correlation was found in only one of nine sport fishes assessed, all correlations were positive indicating a general trend between maximum size of fishes captured with these …

Fisheries Occasional Publication No. 27 - Review Of Pearl Oyster Hatchery Policy - Phase Ii - Policy Direction, Department Of Fisheries, Western Australia

Fisheries Occasional Publications

The Australian pearling industry referred to in this document relates to the Pinctada maxima pearl oyster fishery, the overwhelming majority of which operates in Western Australia and Northern Territory.

The key policy focus was to achieve an alternative supply of shell upon which to conduct the pearl culture process and to develop grow-out competence within the Western Australian pearling industry from the use of hatchery bred pearl oyster spat. It was clearly recognised that it was not economically justifiable for all licensees to have their own hatchery operation but it was felt that all licensees should have the ability to …

Management Of The Proposed South Coast Trawl Fishery. A Discussion Paper., Department Of Fisheries.

Fisheries Management Papers

In late 1987, the Minister approved a development plan for the South Coast Inshore Trawl Fishery (Fisheries Management Paper No. 13) and made a number of notices regulating trawling activities in the Recherche Archipelago. Fishing Boat Licences were subsequently ‘endorsed’ by reference to those notices. The development plan was declared to be for a period ending 31 December 1989, subject to extension for a further year if necessary. Despite the considerable interest in the fishery during 1986 to 1989, fishing results demonstrated that the economic returns were marginal and a number of operators withdrew from participation in the fishery (at …
