Monofilament gill net and trammel net selectivity for the silver crucian carp (Carassius gibelio Bloch, 1782) in the Eğirdir Lake, Isparta-Turkey
The aim of this study was to determine the selectivity of monofilament gillnets with different mesh size for silver crucian carp in Eğirdir Lake. In this study, it was investigated that the selectivity of monofilament gillnets with nominal mesh size (stretched) with 32, 40, 50, 60, 70, 80, 90 mm and trammel nets with 100, 110, 120, 130, 140, 150 mm for catching of silver crucian carp. Fieldwork...

متن کاملGill net selectivity for European hake Merluccius merluccius from southern Portugal: implications for fishery management
A study of European hake Merluccius merluccius gill net selectivity was undertaken off the Algarve (Southern Portugal), between 1999 and 2001. Four nominal mesh sizes (70, 80, 90 and 100 mm) were used in fishing trials and the ‘share each length class catch total’ (SELECT) method was used to fit gill net selectivity curves. Hake were caught in the same size range by all mesh sizes, between 17 a...
متن کاملEffects of gill-net fishing on marine birds in a biological hotspot in the northwest Atlantic.
Marine biological hotspots, or areas where high abundances of species overlap in space and time, are ecologically important areas because energy flow through marine food webs, a key ecosystem process, is maximized in these areas. I investigated whether top predators aggregated at persistent spawning sites of a key forage fish species, capelin (Mallotus villosus), on the NE coast of Newfoundland...
متن کاملMarine macrostomorpha (platyhelminthes, rhabditophora) from the algarve (southern portugal).
Ten species of Macrostomorpha were found in marine environments of the Algarve (Portugal). Six of them were found in the Ria Formosa, a vast intertidal euryhaline lagoon system that dominates the most Eastern coast of the Algarve: two unidentified species of Microstomum Schmidt, 1848, Macrostomum cf. rubrocinctum Ax, 1951 and two unidentified species of Macrostomum Schmidt, 1848, Paromalostomum...
