Cobertura Geográfica

Surveys were conducted at 19 sites in the Masai River Basin in Johor Bahru, Malaysia, focusing on river channels that have been straightened or converted into concrete channels due to urbanization. Additionally, surveys were carried out at 8 sites in the surrounding non-urbanized watersheds to compare the impact of urbanization on the fish populations and river ecosystems.

Dados Sobre o Projeto

The database is sampling results of fish fauna in the highly urbanized and surrounding non- urbanized area (Johor Bahru, Malaysia)

Título Database of Ichthyofauna in Urban Streams of Johor Bahru, Malaysia
Identificador Rei Itsukushima
Financiamento The Kurata Grants No. 1581, The Hitachi Global Foundation
Descrição da Área de Estudo This survey was conducted in the Masai River Basin, located in the southern part of Johor Bahru, Malaysia, covering 19 sites along urban rivers in the basin and 8 surrounding non-urbanized sites. The Masai River is a 7 km-long main river course that flows into the Johor Straits, with a drainage area of 26 km².
Descrição do Design The fishes were collected by hand nets and throwing nets (cast nets) at each habitat (rapid, run, glide, shallows and pool). For each habitat, approximately 20 net casts (half mesh 5.0 mm, 14.0 m in circumference) and 30 min of sampling with a hand net (500 mm in diameter, 6 mm mesh) were conducted.

Descrição dos passos do método:

  1. 1. Data Collection. Field surveys were conducted from November 28 and December 2, 2024 in the sites in Johor Bahru, Peninsula Malaysia. The fishes were collected by hand nets and throwing nets (cast nets) at each habitat (rapid, run, glide, shallows and pool). For each habitat, approximately 20 net casts (half mesh 5.0 mm, 14.0 m in circumference) and 30 min of sampling with a hand net (500 mm in diameter, 6 mm mesh) were conducted. The collected fish were identified to the genus level in the field, and detailed photographs were taken. After the survey, a more thorough identification was conducted. 2. Data Quality Control All specimen identifications were double-checked by taxonomic experts. Duplicate records were removed during data cleaning, and GPS coordinates were verified for accuracy using mapping software (QGIS). 3. Data Processing Coordinates were converted to the WGS84 coordinate system. Taxonomic names were standardized according to GBIF's taxonomic backbone. All measurements were recorded in metric units. 4. Metadata Creation The dataset was described using the Darwin Core standard, including attributes such as location, date of collection, and identifiers. 5. Data Publication The dataset was uploaded to the Pensoft IPT platform and published under the Creative Commons Attribution 4.0 International license (CC-BY 4.0). 6. Data Use This dataset is available for non-commercial use, and users are required to provide proper attribution when using the data in their publications.
