Are Awaous ocellaris and Belobranchus belobranchus the two species of Nike fish schools ?

Investigating goby fish is vital to perform an integrated and comprehensive study in order to maintain the roles of the fish, thus providing balanced ecosystem functions and services, as well as contributing to fish biodiversity. Local societies simply recognize fish species by their local names, which are not common. This condition, in turn, causes hitches in conducting further studies. Nike, the name of a local fish, refers to the schools of goby fish larvae whose adult phase has not been fully confirmed. This study aimed to reveal the species that categorizes as nike fish through tracing adult goby inhabiting freshwater. Two fish samples, i.e., Unknown 01 and Unknown 02, were taken from two sites in Bone River, Gorontalo, Indonesia. These samples were captured purposively using a hand net by considering the morphological similarity between the two target samples and the general characteristic of goby. Furthermore, the samples were analyzed genetically through the PCR sequencing method using the Mitochondrial Cytochrome Oxidase Subunit 1 (CO1) gene. Based on the NCBI database, Unknown 01 had the highest similarity to Belobranchus belobranchus (99.54%), while Unknown 02 was identical with Awaous ocellaris (100%). Unknown 01 and Unknown 02, compared to the BOLD database, the similarity level, had the highest percentage of similarity with B. belobranchus (99.85%) and A. ocellaris (100%), respectively. Therefore, A. ocellaris and B. belobranchus were strongly alleged as two species making up the goby schools in the adult stadia that reach freshwater during their migration

Morphology and growth pattern of Nike fish (amphidromous goby larvae) in Gorontalo Waters, Indonesia

Nike is a terminology used by Gorontalo local community to name schooling of minuscule amphidromous goby fish that has a limited appearance in Gorontalo waters. Understanding the biological performance of Nike fish is vital for implementing management and conservation strategy. This study aims to analyze daily recruitment and to determine growth patterns of Nike fish population in nature. Sampling was conducted in the Gorontalo waters during March, April, and May 2018 using a fish net with a mesh size of 0.5 inches. The duration of the appearance of Nike schooling in waters varies every month. The number of fish samples collected each month in this study ranged from 150 to 300 individuals. This study reveals that body color diversity and morphology of Nike fish strongly alleged to depend on where and how long they appear in the waters. Based on the daily recruitment pattern, Nike fish population distributed in Gorontalo waters is predicted to consist of individuals from multi-generation with an average length range of 1.848–2.805 cm. During the sampling time, a positive allometric growth pattern indicated by the population

Community Structure of Macrozoobenthos in Lake Limboto

This study aims to determine the structure of the macrozoobenthic community in Limboto Lake, Gorontalo Province. Sampling was carried out at 5 stations and 3 repetitions using the Ekman Grab tool and prepared with a filter with a net size of 100 µm. Collecting data using purposive random sampling method and the influence of the macrozoobenthic community structure with physical and chemical parameters was analyzed using the CANOCO 4.5 application. The results showed that the macrozoobenthic community structure in Limboto Lake varied, with the diversity index at Station 1 and Station 2 being in the medium category, Station 3, Station 4 and Station 5 being classified as low, the uniformity index at Station 1 and Station 2 was evenly distributed, Station 3, Station 4 and Station 5 are uneven. The dominance index at Station 3, Station 4 and Station 5 shows that there are species that dominate. The highest total macrozoobenthic abundance was at Station 3, namely 427,643 individuals / m3 and the lowest was at Station 2, namely 2,038 individuals / m3. The results of the analysis showed that the substrate had the greatest influence on the macrozoobenthic community structure and was followed by other physical-chemical parameters.
