- Análisis de la pesquería y dinámica poblacional de la vivita de hebra (üpisthonema ogiinumj en Yucatán, México Guadalupe Mexicano-Cíntora Silvia Salas Miguel A. Cabrera Ciencias de la Tierra Yucatán thread herring population dynamics The artisanal fishery of Atlantic thread herring (Opisthonema oglinum) in the coastal region offCeiestún, Yucatán, began in 1991 in response to an increase in the demand. by the Yucatán industrialíishing fleet, to use it as bait in the capture of other demersal species. A characterization of the fisheryin terms of fishing methods, fishing grounds and catch composition is made for the 1993-94 period.The estimated mean catch per trip was 344 kg, obtained in nine effective hours of fishing. The variablecosts per trip are lower than the incomes, but there is not enough inlòrmation to makc infcrencesabout the economic aspects of the fishery. A preliminary analysis of thc population dynamics of thisspecies was carried out. The estimated growth parameters were: Lm = 227 mm FL and K = 0.68iycar.Recruitment patterns showed a long period throughout the year, with a maximum in summcr. 1996 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48022103 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.1 Vol.22
