    Abstract:

    Abstract The mullet Mugil Liza is distributed along the Atlantic coast of South America, from Argentina to Venezuela, and it is heavily exploited in Brazil. We assessed patterns of distribution of neutral nuclear genetic variation in 250 samples from the Brazilian states of Rio de Janeiro, Sao Paulo, Santa Catarina and Rio Grande do Sul (latitudinal range of 23–31°S) and from Buenos Aires Province in Argentina (36°S). Nine microsatellite loci revealed 131 total alleles, 3–23 alleles per locus, He : 0.69 and Ho : 0.67. Significant genetic differentiation was observed between Rio de Janeiro samples (23°S) and those from all other locations, as indicated by F st , hierarchical analyses of genetic structure, Bayesian cluster analyses and assignment tests. The presence of two different demographic clusters better explains the allelic diversity observed in mullets from the southernmost portion of the Atlantic coast of Brazil and from Argentina. This may be taken into account when designing fisheries management plans involving Brazilian, Uruguayan and Argentinean M. Liza populations.

  • age growth and mortality of the mullet mugil Liza in brazil s southern and southeastern coastal regions
    Fisheries Research, 2014
    Co-Authors: Thais Garbin, Jorge Pablo Castello, Paul Gerhard Kinas
    Abstract:

    Abstract Concern has increased regarding the stock exploitation status of the mullet, Mugil Liza, fishery resource, because industrial catches currently exceed artisanal catches. A growing trend in mullet catches involves the overexploitation of other resources and the commerciaLization of mullet roes. This study complements existing information about the mullet's life cycle by providing estimates on growth and mortality rates for the stock. The mullet, M. Liza, has a relatively low growth rate, κ, at approximately 0.17 year−1, a 10.5 year longevity, and an asymptotic length of 662 mm. Based on age–length structure, mullet caught at sea, in both coastal areas and continental shelves, are significantly larger and older than mullet caught at the Patos Lagoon Estuary by artisanal fishermen. The total mortality rate, Z, was estimated to be approximately 0.77 year−1, and the exploitation rate was higher than 0.5 in 3 different scenarios tested with different natural mortality rates calculated in this work.
