Abstract
Neotropical cichlid possesses territorial aggression which explains their success as alien species that pose threats to local fauna. The feeding ecology of Midas cichlid, Amphilophus citrinellus species outside its native range had never been fully understood. We aim to determine the stomach content, length-weight relationship and condition factor of this non-native species in one of the agroecosystems in Malaysia. The fish was collected using a cast net, and the guts were dissected. The stomach content (n = 35) revealed Midas cichlids feed on a wide array of preys including fish, amphibian and gastropod. The b-value is 2.60 (negative allometric growth) and the relative condition factor, Kn is 1.04. This result represents an initial study on the feeding aspect of this cichlid. Subsequent and continued researches are needed to evaluate the feeding behaviour and prey preferences of this species in its introduced range.
期刊介绍：
Tropical Life Sciences Research (TLSR) formerly known as Journal of Bioscience seeks to publish relevant ideas and knowledge addressing vital life sciences issues in the tropical region. The Journal’s scope is interdisciplinary in nature and covers any aspects related to issues on life sciences especially from the field of biochemistry, microbiology, biotechnology and animal, plant, environmental, biomedical and pharmaceutical sciences. TLSR practices double blind peer review system to ensure and maintain the good quality of articles published in this journal. Two issues are published annually in printed and electronic form. TLSR also accepts review articles, experimental papers and short communications. The Chief Editor would like to invite researchers to use this journal as a mean to rapidly promote their research findings.
