Abstract

Foreign fish, especially predatory fish in Indonesian public waters, are very dangerous for the local ecosystem, foreign predatory fish can become the main predators and can cause an imbalance in the ecosystem. From this study we report the catch of foreign predatory fish from the jaguar cichlid species (Parachromis managuensis) from Central American waters caught in Nyunyur Reservoir, Blitar Regency, East Java. The method in this study used a desk study and jaguar cichlid species identification method using morphological observations based on Kullander and Hartel (1997). This catch is a warning and an important note for the relevant agencies regarding the invasion of the jaguar cichlid species in the Nyunyur Reservoir as an initial step in monitoring aquatic ecosystems.

Abstract

Foreign predatory fish species in Indonesia have the potential to threaten the local ecosystem by becoming the main predators that disrupt the balance of the food chain in local waters. Through this research, we want to report the invasion of the species Parachromis managuensis, which originates from Central American waters. This fish species has been found in significant numbers and sizes in the waters of the Penjalin reservoir. In this study, a morphological approach was used to identify the Parachromis managuensis species. The capture of this species was recorded as the first step in efforts to monitor the reservoir water ecosystem in Brebes so that it remains balanced. Results and discussion, including a description of the morphology of the Parachromis managuensis species that have been caught, can be found in this research report.
