    Catch Composition and Size distribution of the spiny lobster (Panulirus spp) Related to Oceanography Parameters of the Southern Coast of South Sulawesi
    (2016-03-30) Musbir; Sudirman; Bohari, Ridwan
    Spiny lobsters (Panulirus spp) are economically important crustaceans due to their value as a food. The spiny lobster caught generally by traps and bottom gillnets sometimes by divers support significant commercial catches along the South Sulawesi coast. The objective of the present study was to analyses Catch composition and Size distribution of the spiny lobster related to oceanography parameters. The study was conducted from March to August 2014 on the south coast of Bulukumba, South Sulawesi. Bottom gillnet was used in this study to catch the spiny lobsters Oceanography parameters such as temperature, salinity, and current velocity were used to relate the lobster catch from the coastal fishing grounds during the fishing season. Catch composition of spiny lobsters consist ofP.ornatus47.5 %, P. homarus25.8 %, P. versicolor 21.2 %, P. penicilatus 11 %. Carapace length of P. ornatus with most of the individuals sized from 41-50 mm, P.homarus51-60 mm, P. versicolor 41-60mm, P. penicilatus41-50 mm. The Oceanography parameters recorded from the fishing ground during fishing period were well within the optimum ranges such as temperature (27-29ºC), salinity (30-31 ‰), and current velocity (004-0.09 m/sec).

    The Current Speed, Depth and Catch Per Unit Effort of Bottom Gill Net in Southern Bulukumba Coast, South Sulawesi
    (2016-04-02) Musbir; Sudirman
    The objective of this study was to analyses catch per unit effort of bottom gill net related to current speed and water depth in southern Bulukumba coast, South Sulawesi. The study was conducted from April 2010 to November 2011. Fish catches were monitored to describe the predominant species caught. The length of gill net was 500 m and depth 5 m. Mesh size was 6 cm and shortening 45 %. Total catch was decrease with increase current speed. The highest catch was occurred in current speed 0.08 msec-1. In contras, the lowest catch was occurred in current speed 0.31 msec-1. Altogether 13 species were identified from 4 fishing efforts of bottom gill net. The average catch per unit effort per day in fishing ground with less than 20 m in depth was 21.2 kg. On the other hand, in more than 40 m in depth was 30.2 kg. Total catch was strongly related to water depth.
