Dimensional Analysis of Cantrang Fishing Gear and its Implications for the Ecology and Biology of Fish in the Ancam River Estuary, North Kalimantan, Indonesia

Abstract

The cantrang fishing gear is a type of fishing gear that is operated on the bottom of the waters by pulling it so that it is feared to have implications for damage to the ecosystem and biology of aquatic resources. This study aims to analyze the dimensions of the cantrang fishing gear based on Indonesian national standards (SNI) 01-7236-2006 and its implications for the ecology and biology of aquatic resources. This research is classified as a qualitative research type and was conducted using survey and interview methods. The research was conducted from March to May 2025 on the fishing gear used by fishermen in the Ancam River estuary, North Kalimantan. The results of the study showed that the longitudinal comparison of the parts of the cantrang fishing gear was in accordance, smaller and larger than SNI, in the transverse section all were smaller than SNI, the comparison of the number of grids on the cantrang section only the bag section was in suitable while the other parts were smaller, the material was all in suitable, while the mesh size was only the bag section that was in accordance while the others were all smaller. The dimensions of the cantrang fishing gear that did not comply with SNI had implications for damage to the basic aquatic ecosystem, disruption of the food chain and web, decreased catches, catching aquatic resources that had not reached a suitable size for catching. The dimensions of the cantrang fishing gear had differences in several parts so that they had an impact on the ecosystem and biology of aquatic resources.
