| dc.description.abstract | Research on the Identification Study of Freshwater Fish Species and its
Relationship with Water Quality in Batang Gadis River, Mandailing Natal
Regency, North Sumatra Province aims to determine the types of fish found in
Batang Gadis River, Mandailing Natal Regency, North Sumatra Province and to
determine the relationship of water quality to the abundance and diversity of fish
in Batang Gadis River, Mandailing Natal Regency, North Sumatra Province. This
research was conducted from January to March 2024. The results showed that the
types of fish found in the Batang Gadis River, Mandailing Natal Regency, there
were 10 types of fish found, namely the Yellow Seluang fish (Rasbora lateristriata),
Cencen fish (Mystacoleucus marginatus), Goldfish (Cyprinus carpio), Sepatung
(Pristolepis grootii), Tilan/Lonjing (Mastacembelus erythrotaenia), Lelan
(Diplochelichthys pleurotaenia), Gabus (Channa striata), Nilem/Aporas
(Osteochilus vittatus), Tilapia (Oreochromis niloticus) and Baung (Hemibagrus
nemurus). The relationship of water quality to the abundance and diversity of fish
in the Batang Gadis River, Mandailing Natal Regency, North Sumatra Province
such as physical parameters, namely temperature, brightness, current speed, and
TSS has a very strong interpretation, while depth has a strong interpretation.
Chemical parameters namely DO have a very strong interpretation while pH has a
strong interpretation. | en_US |
