Effects of stocking densities in blood chemistry and biochemical body composition of Nile tilapia Oreochromis niloticus and the prawn Macrobrachium americanum in polyculture

Abstract

ABSTRACT. An assay on tilapia Oreochromis niloticus and freshwater prawn Macrobrachium americanum in polyculture was conducted during 112 days to study the effect on their blood chemistry and biochemical body composition to determine the feasibility of this polyculture in high density. Six densities were evaluated [T4/5, T9/5, T14/5, T0/5, T9/0, and T14/0; Ttilapia/prawn (ind m -2 )]. In tilapia were evaluated hemoglobin, red cells albumin, globulin, cholesterol, glucose, and triglycerides composition in blood. In M. americanum were evaluated hemocyanin, cholesterol, triglycerides, glucose and total protein in hemolymph. The total content of proteins, lipids, and carbohydrates in muscle and liver of tilapia, and muscle and hepatopancreas on prawns were also studied. Both animals presented significant differences (P < 0.05) in the glucose concentration, tilapia at T9/5 density presented significantly lower concentration (26.25 ± 6.3 mg dL -1 ) in blood, and prawn at T4/5 presented significant higher concentration (12.2 ± 1.9 mg dL -1 ). Tilapia monocultures T14/0 displayed significant higher (P < 0.05) carbohydrate concentration in muscle. No significant differences (P > 0.05) appeared in the concentration of lipids and proteins in any tilapia group and proximal composition of muscle and hepatopancreas in prawn. The present study indicates that polyculture in a density T14/5 is similar than monoculture with no effect in blood or hemolymph chemistry and proximal composition of tilapia and prawn. The blood glucose concentration can be considered an indicator of physiological changes for tilapia and prawn when cultured together.

Evaluation of some haemolymph biochemical properties and F‐cell prevalence in hepatopancreas of white leg shrimp (Litopenaeus vanammei) after fed diets containing apple cider vinegar and propionic acid

“…In addition, cortisol level in L. vannamei fed commercial diet plus indigenous probiotic was not significantly different compared with control group. The fluctuation of albumin level reflects changes in nutritional, ecological and health status (Kovyrshina & Rudneva, 2012;Santamaria Miranda et al, 2018). Moreover, the concentration of albumin has identified as a good marker to determination of liver function and inflammation (MacQueen, Sadler, Walker, Wassif, & Evans, 2011).…”

“…Research in crustacean biochemistry has developed in recent years, because it is useful for controlling health and nutritional condition of culture (Mercier et al, ; Pourmozaffar, Hajimoradloo, Paknejad, & Rameshi, ). A number of researchers evaluated biochemical variables in various conditions such as salinity stress (Lee & Chen, ), dietary regime (Zhao et al, ), stocking density (Santamaria Miranda et al, ) and different ecological place (Adeogun, Salami, Chukwuka, & Alaka, ). Therefore, the measuring of these indices is necessary to understand how shrimp health is affected by the internal physiological state and the external environment.…”

The culture potential and management problems of freshwater prawns (Macrobrachium americanum and Macrobrachium tenellum) in their native areas: the case for Mexico

“…The effect of stocking densities on blood chemistry and biochemical body composition of this prawn cultured and the Nile tilapia (Oreochromis niloticus) were evaluated by Santamaría-Miranda et al (2018). The results revealed that a combination of 14 fishes per five prawns produced similar growth compared to a monoculture, with no effect on blood or hemolymph chemistry and proximal composition on any species.…”
