Description
The study explored, examined and simulated some selected abiotic factors observed at
biodiversity hotspots of Osse River, located in the tropical Rainforest, Edo State, Nigeria. The
study was aimed at providing information required for sustainable shrimp husbandry. The
research rationale was that the stress levels in shrimps are absolutely a function of flow rates and
depths. Shrimp samples were caught from Osse River at night and early morning periods. The
shrimp samples were identified, sorted, and counted. Stress levels impacted by abiotic variables
such as regulated flow rates and depths were investigated employing Glutathione-S-Transferase,
Cytochrome P450 mono-oxygenase, Catalase, and Superoxide dismutase. M. vollenhovenii
managed the stress the most, followed by M. macrobrachion. These potentials can be attributed
to the relatively large and tough morphological characteristics and the animals. Proficiency of
regulation of antioxidant enzymes in the animals must have contributed appreciably to the
hardiness of the animals. Cultivation of M. vollenhovenii, followed by M. macrobrachion is very
much achievable, with optimal results at flow rate of 0.1 m/s. The species have an appreciably
wide spectrum of flow rates due to their ability to cope in slightly harsh conditions. The study
provided vivid information on the flow rate of shrimp pond to support artificial rearing of the
Palaemonid shrimps
