Abstract

ABSTRACT: The rabbitfish, Siganus canaliculatus is one of the components in the coastal waters ecosystem (mangrove, seagrass, and coral reef) and also has important economic value for coastal communities, but information is still limited, especially in Papuan waters. This study aims to analyze the size composition and growth patterns of rabbitfish (Siganus canaliculatus) based on habitat differences in the waters of Kwatisore, Yaur District, Nabire Regency. Sampling was carried out at three locations representing various habitat types, such as mangrove, seagrass, and coral reef. The data collected included the total length (mm) and body weight (g) of the fish, which were then analyzed using the length-weight relationship model W = aLb. The results showed that the average body length and average body weight were greater in the coral reef habitat type, but relatively the same among the three research locations. The overall growth pattern (habitat type and location) with a tendency for body length to increase faster than body weight (negative allometric pattern) with a b value ranging from 2.771 to 2.888. The size and growth patterns obtained in this study indicate connectivity between locations and habitats, although both habitat types show different roles in the life cycle of this fish. This study provides important information for ecosystem-based management of the rabbitfish resource in the coastal area of Nabire.

Abstract

ABSTRACT: This study examines the microhabitat characteristics of the endemic rainbowfish Melanotaenia arfakensis in two major rivers of Tambrauw, Southwest Papua—Api River and Asiti River—focusing on the spatial dynamics of environmental parameters from upstream to downstream. Results indicate that water temperature, dissolved oxygen (DO), depth, current velocity, and river width show significant spatial trends and directly influence the survival of M. arfakensis. The upstream zones, characterized by lower temperatures (23–26°C), high DO levels (>7 mg/L), moderate current, and stable depth, are identified as optimal habitats and conservation priorities. In contrast, the midstream and downstream zones exhibit gradual habitat degradation, including temperature increases up to 29.1°C and decreased DO levels, approaching the physiological tolerance limits of the species. This decline in microhabitat quality correlates with riparian vegetation loss and anthropogenic pressures. Therefore, an effective in situ conservation strategy must be spatially explicit, adaptive, and participatory—emphasizing thermal refugia protection in the upstream zones, ecological restoration in the midstream, and integrated watershed management with community involvement in the downstream areas. Longitudinal connectivity and the integrity of the entire riverine ecosystem are essential for ensuring the long-term viability of this endemic species.
