ABSTRACT


GRACE RIJOLY, SN: 2005-64-001. COMPOSITION AND STOK ABUNDANCE OF FLYING FISH IN THE SURROUNDING WATERS OF HUKURILA VILLAGE, SOUTH LEITIMUR DISTRICT OF AMBON CITY. SUPERVISED BY: D.  SAHETAPY AND S. HAUMAHU.


Research was conducted on March to July 2012 in Hukurila Village and surrounding waters. The aims of research are to identifying taxon composition, describe species and analyses stock abundance, as well as Catch Per Unit of Effort (CPUE) value of flying fish in the Hukurila Village and surrounding waters.  Flying fish data were conducted using drift gill net that operated toward the night (18.00 – 21.00 WIT) and in the morning (06.00-10.00 WIT) base on moon age period. Sample of flying fish that obtained than identified follows Weber and Beaufort (1922), Munro (1967) Parin (1999). Analysis of morphometric and meristic parameters were conducted follows Munro (1967); Trautman (1957) in Lagler et al., (1977); Gloerfelt-Tarp and Kailola (1984); Rijoly (1987); and Parin (1999). Density and stock abundance of flying fish were analyzed use method that recommended by Gunderson (1993) and  Sparre and Venema (1999). At least 17 species of flying fish belonging to 4 genera occupies in Hukurila Village and surrounding waters, where all of these flying fish species have been analyzed and compiled its description. Distinguishes characters of these 17 flying fish species existed black spot and motif cross band on features of Pectoral Fin, Ventral Fin and Dorsal Fin, branch on lateral line, and number of rays without branches on pectoral fins. The highest density and stock abundance of  flying fish were found on the last quarter, while the lowest density and stock abundance of flying fish were occupied on full moon. Potential time for utilization the flying fish is toward the morning time, that is between 06.00 - 10.00 of East Part Indonesian Time for each moon period. Based on duration of drift gill net operating, than the highest CPUE value of flying fish were occupied on the last quarter and the lowest CPUE value on full moon period. On the other hand, based on the gill net drifting distance, so that the highest CPUE value were found on first quarter and the lowest CPUE value on full moon period. Cheilopogon cyanopterus is a dominance flying fish species in catch, and its have the highest density, stock abundance and CPUE value on all moon period.
