UNDERSTANDING THE BIOLOGY AND ECOLOGY OF CLARIAS BATRACHUS: AN INVASIVE AND ECONOMICALLY IMPORTANT SPECIES

Abstract

This research paper aims to comprehensively examine the biology, ecology, and economic
significance of Clarias batrachus, emphasizing its invasive nature and implications for both
natural ecosystems and human activities. Through a review of existing literature, this paper
explores the taxonomy, morphology, reproductive biology, and life cycle of Clarias
batrachus, along with its ecological impacts on native ecosystems and its economic
importance in aquaculture. Clarias batrachus, commonly known as the walking catfish, is a
freshwater fish species native to Southeast Asia but has become invasive in many parts of the
world. Clarias batrachus belongs to the kingdom Animalia, phylum Chordata, class
Actinopterygii, order Siluriformes, family Clariidae, and genus Clarias. It is commonly
known as the walking catfish or freshwater air-breathing catfish. The reproduction and life
cycle of Clarias batrachus involve several stages, including courtship, spawning, egg
development, and early life stages. Additionally, it discusses current control and management
strategies for mitigating its spread and outlines future research directions for improved
conservation efforts.
