  • predation risk within Fishing Gear and implications for south australian rock lobster fisheries
    PLOS ONE, 2015
    Co-Authors: Felipe Briceno, Juan Carlos Quiroz, Adrian Linnane, C Gardner, Gretta T. Pecl
    Abstract:

    Depredation of southern rock lobster (Jasus edwardsii) within Fishing Gear by the Maori octopus (Pinnoctopus cordiformis) has economic and ecological impacts on valuable fisheries in South Australia. In addition, depredation rates can be highly variable resulting in uncertainties for the fishery. We examined how in-pot lobster predation was influenced by factors such as lobster size and sex, season, Fishing zone, and catch rate. Using mixed modelling techniques, we found that in-pot predation risk increased with lobster size and was higher for male lobsters. In addition, the effect of catch rate of lobsters on predation risk by octopus differed among Fishing zones. There was both a seasonal and a spatial component to octopus predation, with an increased risk within discrete Fishing grounds in South Australia at certain times of the year. Information about predation within lobster Gear can assist fishery management decision-making, potentially leading to significant reduction in economic losses to the fishery.

  • Mesh sticking probability in Fishing Gear selectivity: Methodology and case study on Norway lobster (Nephrops norvegicus) and mantis shrimp (Squilla mantis) in the Mediterranean Sea creel fishery
    Hellenic Centre for Marine Research, 2019
    Co-Authors: Brcic Jure, Herrmann Bent, Baranovic Mateja, MaŠanoviĆ Marina, Šifner, Svjetlana KrstuloviĆ, Škeljo Frane
    Abstract:

    Fish or crustaceans stuck in the Fishing Gear meshes can lead to operational problems in some fisheries and thereby affect theeconomic gain. However, mesh sticking probability has never been formally quantified as a part of the estimation of Fishing Gearsize selectivity. Therefore, this study developed a size selection model and estimation procedure that, besides the size dependentretention and escape probabilities, includes the size dependent mesh sticking probability. The new method was applied to quantify the size dependent retention, sticking and escape probabilities for mantis shrimp (Squilla mantis) and Norway lobster (Nephrops norvegicus) in creels with 41 mm square mesh netting. The mesh sticking probability was found to display a bell-shaped curvature with a maximum value for a specific carapace length and decreasing probabilities for both smaller and bigger individuals. For mantis shrimp the maximum sticking probability was found for 32.5 mm carapace length with a value at 13.5%, while 63.1% and 23.4% of that size were respectively retained inside the creels and escaped. For Norway lobster the maximum sticking probabilitywas 2% and occurred for 34.0 mm carapace length. The method and estimation procedure presented in this study might be applicable for quantifying mesh sticking probability as an integral part of future Fishing Gear size selectivity studies on other speciesand fisheries
