Comparative study of body composition of different fish species from brackish water pond

Abstract

Seven species of fish (Catla catla, Cirrhinus mrigala, Cyprinus carpio, Hypophthalmicthys molitrix, Labeo rohita, Mori-Rahu Hybrid and Thalla-Rahu Hybrid) were collected from a brackish water pond near Muzaffargarh, Pakistan for the comparison of body composition. All the seven species were found relatively well adapted to the saline environment though some of them showed significant differences in body composition. Results obtained did not show any adverse effect of salinity on these fish species. The mean values of body constituents, except for protein content (dry and wet body weight) differed significantly (P<0.05) among various fish species. Minimum amount of water content and maximum amount of lipids, organic content and condition factor were observed in Cyprinus carpio indicating that Cyprinus carpio show overall better growth in brackish water as compared to other species. Cyprinus carpio may be recommended for culturing in such water bodies and farmers may be encouraged to farm this species on mass scale.

Length-weight relationship and prediction equations of body composition for growing-finishing cage-farmed Nile tilapia

“…However, whole-body composition follows a similar pattern among different species as fish size increases (Lupatsch et al, 2001;Dumas et al, 2010), and the live weight of the majority of fishes consists of approximately 700-800 g kg −1 of water, 200-300 g kg −1 of protein, and 20-120 g kg −1 of lipid (Love, 1980). The whole-body composition of fish is affected by species (Ali et al, 2005), environmental parameters , nutrition, and body size (Ebrahimi and Ouraji, 2012). Information on body composition related to fish size can be used to select fish with higher protein contents at a specific size, for human consumption (Ali et al, 2005).…”

“…Fish represents one of the main sources of protein in developing countries (Louka et al, 2004). The moisture content is a good indicator of body protein and lipid contents (Ali et al, 2005), as observed in this study ( Figure 2); lower moisture percentages are associated with higher lipid contents in fish (Dempson et al, 2004). Hartman and Margraf (2008) reported a significant fat-water relationship and developed models to predict the proximate composition for chum salmon (Oncorhynchus keta), rainbow trout (Oncorhynchus tshawytscha), brook trout (Salvelinus fontinalis), and striped bass (Morone saxatilis).…”

Comparative study of body composition of four fish species in relation to pond depth

“…All measurements were made from the tip of the maxilla to the longest caudal fin ray. Details of experimental procedures are provided elsewhere (Ali et al 2005). Water content was determined by placing the whole fish in a pre-weighed aluminum foil tray for drying in an electric oven at 65-80 o C till constant weight.…”

Effect of Poor Handling on the Nutritional Composition of Some Imported Frozen Fishes in Nigeria

“…Fish of various species don't provide the same nutrient profile to their consumer (Takama et al, 1999) The nutrients values however, vary considerably within and between species, and also with size, sexual condition, feeding, time of the year and physical activity (Ali et al, 2005). According to Muraleedharan et al (1996), the chemical composition of fish varied from 16-21% proteins, 0.1-25% lipids, 0.4-1.5% ash and moisture 60-81% with extremes of 96%.…”
