Biochemical Analysis of some Selected Species of Macrophytes and their Effects on Fish Growth from Kori Lake District Thatta Sindh

Abstract

Macrophytes constitute important components of many freshwater ecosystems. Macrophytes play fundamental roles in nutrient cycling of water bodies and provide suitable habitats for many other animals. This study was conducted to evaluate the food potential of macrophytes for aquatic fauna; macrophytes were collected for their biochemical composition (total lipids, carbohydrate content and total protein content) from Kori Lake District Thatta.The five of these macrophytes Typha latifolia L, Bacopa monnieri L, Phragmites australis Adans, Lemna minor L., Valisnaria L., Salvinia molestaD. Mitchwere collected for biochemical analyses. The total moisture percentage in Typha latifolia in leaves, stem and rhizoids varied between 62.53, 43.22 and 65.33 respectivelyduring summer June while in case of winter season the values ranged between 42.97, 30.40 and 49.77 respectively. The percentage of lipid of Nelumbo nuciferaleavesand stem and rhizoids varied between 1.82 and 1.51 during summer while during winter season 1.29 and 1.42
