ABSTRACT
Timbulsloko waters is coastal areas that are densely human activity, such as fishing and aquaculture. This activities can give impact to the biota resources and fish larvae. The fish larva is the phase of fish’s life cycle after the eggs hatch. In this phase, the formation of fish's organs is not yet fully formed, weak, and very dependent on the water movement. The objective of this study was to determine the composition, the type and the abundance of fish larvae based on tides that found in the waters of Timbulsloko Village, Sayung District, Demak Regency. This study was conducted from November to December 2018. This study used a survey by determining the sampling points using purposive sampling conducted at 5 stations in the high tide and low tide. The results showed that the number of fish larvae caught were 1.106 individuals consist of 8 families, such as: Ambassidae (510 individuals), Chanidae (60 individuals), Engraulidae (49 individuals), Gobiidae (59 individuals), Leiognathidae (54 individuals), Lutjanidae (36 individuals), Mugilidae (279 individuals), Scatophagidae (59 individuals). Ambassidae family larvae was the most caught larvae, while Lutjanidae family larvae was the least amount caught. The results of multiple linear regression analysis showed that the correlation coefficient (R) was 0,841 and the coefficient of determination (R2) was 0,708. The results of the Independent-Sample T-test showed that there was no significant difference between the abundance of fish larvae in the high tide and low tide from every station and repetition. The number of fish larvae is 600 individuals and 506 individuals in the high tide and low tide, respectively.
