Impact of emergent macrophytes on fish catch in Nguru Lake


MM Abubakar

Abstract

The impact of emergent macrophytes on the catch of fish in Nguru Lake was studied from May 2006 to April 2007.Physico-chemical properties of the lake were studied in conjunction with the macrophytes. Experimental fishing was carried out in portions of the lake infested with the macrophytes and portions not infested.data collected were subjected to Student,s t-test. There was
significant difference between fish catch in the two portions.. The infestation of macrophytes particularly Typha sp. leads to poor fish yield. The study recommended that farmers should be enlightened on the use of organic fertilizers and other safe farming practices and that further research should be carried out on the proliferation of Typha.
