ABSTRACT

A study on food habit of Betok Palu  (Chrysiptera hemicyanea) in  Coral Reef Lara Island was conducted from Februari to March 2005. Aims of the study were to analysis food habits, relation of the food habits and plankton in that waters.  Food Habit was determined by using Index of Prepoderance method.  Results of the study indicated that the main food of male and female of the fish was Cyanophyceae (48,13%), while Bacillariophyceae, Chlorophyceae, Desmidiaceae, Ciliata dan MTT was a complement food, and Pyrophyceae, Xanthophyceae, Rhizopoda, Rotatoria, Ctenophora dan Copepoda was found as supplement food for the fish. Food habit of betok palu change as according to condition of waters influencing the availibility of plankton in the waters. 

Key Words : Betok Palu  (Chrysiptera hemicyanea) , food habits, Coral reef and plankton

Abstract
Research on growth of fringescale sardinella was carried out from August 2009 to February 2010 in Kendari Bay, Southeast Sulawesi. Fish collection was done experimental gillnets (with different mesh sizes ¾, 1, 1¼, 1½, and 2 inch) and seser (Ø 1 meter and mesh size 0.04 inch). A total of 1069 individual fish were caught with range from 1.5 – 16.2 cm in length and 2.8 – 34 g in weight. The length-weight relationship was y = 3.034x - 2.052 (males) dan y = 3.041x - 2.052 (females). The von Bertalanffy growth models was . The relative condition factors of fish varied from 0.47 to 2.95, with females were generally in better condition than the males.

Key words: growth, Sardinella fimbriata, Kendari Bay

ABSTRACT
Research on ontogenetic dietary variation rainbow sardine relating to body size of fish with time was carried out from August 2009 to January 2010 in Kendari Bay, Southeast Sulawesi. This research aims to describe ecological role of rainbow sardine in Kendari Bay. Fish collection was done using experimental gillnets (with different mesh sizes ¾, 1, 1¼, and 1½ inch) and scope net (Ø 1 meter and mesh size 0.04 inch). A total of 136 individual fish were caught with range from 0.6 to 15.7 cm in length. Food analysis was determined by using Index of Preponderance. Result of the analysis indicates rainbow sardine is planktivora, which important diet is Bacillariophyceae. The male and females of fish did not have ontogenetic dietary (main food) shift and was not ontogenetic dietary shift relating to body size of fish. The diet of the fish every months was dominated by Bacillariophyceae.

Key words: body size, diet, Kendari Bay, ontogenetic, rainbow sardine, time.

ABSTRACT
Research on fish diversity was carried out from August to October 2009 with three times of sampling in three stations in Kendari Bay, Southeast Sulawesi. Fish collection using experimental gillnets (with different mesh sizes ¾, 1, 1¼, 1½, 2, 3, and 4 inch) and seser (Ø 1 meter and mesh size 0.04 inch). During research, 45 species of 30 families were collected. Based on individual quantities, at the first sampling, Sardinella fimbriata was dominant species on Station I and II, S. longiceps on Station III; in the second sampling, S. fimbriata was dominant species on Station I, S. longiceps on Station II, Plotosus canius on S3; in the third sampling, Ambassis sp. was dominant species on Station I, S.longiceps on Station II, Upeneus suphureus and Stolephorus commersonii on S3. Diversity index (H’) was range between 0.51-2.25, dominance index (C) was range between 0.16-0.83 and evenness index (E) was range between 0.19-0.75.

Key words: fish diversity, Kendari Bay
