Spatial dispersal and growth pattern of “nike” fish (apmhidromous goby larva) in Gorontalo, Tomini Bay

Abstract Assessment of distribution and population growth are fisheries dynamic aspects required to be observed periodically address sustainable management. This research aimed determine spatial dispersal, daily patterns, condition factor Nike fish as amphidromous schooling larvae in Gorontalo Waters, Tomini Bay. The number 1808 larva samples were collected for eleven consecutive days during its natural appearance August 2022. Based on total-length frequency distribution, the schools performing this period presumably comprise more than one age group. Allometric positive patterns shown 2, 4,7, 10 11. In contrast, isometric exhibited 1, 3, 5, 6, 8, 9. highest lowest values seventh day (length class interval 32.1-33.6 mm) fifth 28.9-30.4 mm), respectively. result indicated that factors fluctuated among their Bone Estuary. It is understandable critical stages larvae, such varying salinity, competition food niche, fishing pressure factors, must undergo estuary highly environmental conditions.
