This book was released on 1980 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: An evaluation of marks on scales, vertebrae, and otoliths for age determination of Atlantic croaker, spot, sand seatrout, and silver seatrout was performed. Otoliths showed the most potential for accurate age determina- tion of these species. Otolith radii and marks had high positive correlations with fish total lengths in all four species. Reasonable agreement was found between lengths at capture and backcalculated lengths based on otoliths, for all four sciaenids

Book excerpt: An evaluation of marks on scales, otoliths, vertebrae, and dorsal and anal fin rays for age determination of pompano, ladyfish, crevalle jack, gulf flounder, and southern flounder was performed. Otoliths were selected as the most suitable age-determination structure. Otolith radii and marks had high positive correlations with fork lengths for pompano, ladyfish, and crevalle jack, and with total length for gulf flounder and southern flounder.

Corvino and published by . This book was released on 1994 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Southeast Fisheries Science Center (SEFSC) is one of five regional fishery research centers of the National Marine Fisheries Service (NMFS). In 1970, the NMFS was organized as a component of the National Oceanic and Atmospheric Administration (NOAA) in the U.S. Department of Commerce. The Fisheries Science Centers provide scientific information required for decisions relating to the conservation and management of fishery resources, and the protection of fishery habitats, endangered and threatened species. In 1972, the NOAA Technical Memorandum series was established and the Southeast Fisheries Science Center began the publication of research reports. The purpose of this series is timely dissemination of the results of scientific research. The series also affords the SEFSC a means of publishing research results in greater depth and detail than is normally allowed by scientific journals, which usually have stringent length restrictions. To address the difficulties of identification and location of these publications, we present the following listing of SEFSC Technical Memoranda from number 1 (1972) to number 340 (1993). They are available from their originating laboratories or from the National Technical Information Service. A directory of these sources is provided on page 2"--Introduction

Book excerpt: "Study objectives: 1) To conduct a comprehensive study of seasonal movements and migration patterns of the eleven most important inshore marine recreational species of sportfishes. 2) To determine age and growth characteristics (time of annulus formation, size at various annuli,k rates of growth, etc.) of the eleven target species. 3) To determine the food preferences and feeding habits of the target species and determine if seasonal and/or developmental changes in habits or diets occur. 4) To determine the reproductive characteristics (time of spawning, location of spawning, age at maturity, fecundity, etc.) of the target species."--p.ii.

Barger and published by . This book was released on 1980 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The literature dealing with age and growth of spot (Leiostomus xanthurus), sand seatrout (Cynoscion arenatius) and silver seatrout'(C. nothus) was reviewed. Length-frequency analysis was the most frequently used technique for ageing the three species; however, size overlap renders the technique progressively unsuitable as the fish grow older. Otolith and scale analysis, both of which have been verified as usable for ageing spot, yielded reported ages of up to 3 and 4.5 years respectively. A mathematical summary of age and growth information was developed using least-squares regression analysis. A composition growth rate (Y A:Tu where Y - mean total length in millimeters, X = mean age in months, A = 6.89 x 10-2, and B = 2.20 X 10-3) was obtained. Length-frequency analysis was the only successful method reported for ageing the two seatrouts. Up to three age classes have been identified for sand seatrout. The life span for silver seatrout has been estimated as being little more than one year. Analysis of growth of the seatrouts was not possible due to insufficient data. The techniques used and the problems involved are discussed and recommendations for future work are made.
