Tilapia production in Ghana has been hit with episodes of stress and pathogen-induced mass fish kills which have anecdotally been linked to the culture of illegally imported Genetically Improved Farmed Tilapia(GIFT)strains of Nile tilapia,Oreochromis *** study was thus set up to comprehensively assess the stress tolerance of the GIFT strain and a native strain of Nile tilapia(the Akosombo strain)following exposures to hyperthermic and hypoxic *** a series of experiments,oxygen consumption(MO_(2)),aquatic surface respiration(ASR),thermal limits and hypoxia tolerance were *** effects of these stressors on haematological parameters were also *** GIFT strain was less tolerant of hypoxia and performed ASR at higher O_(2) levels than the Akosombo *** progressive hypoxia,the GIFT strain exhibited higher gill ventilations frequencies(fV)than the Akosombo *** thermal tolerance trial indicated that the Akosombo strain of *** has higher thermotolerance than the GIFT strain and this was reflective in the higher LT_(50)(45.1℃)and LT_(max)(48℃),compared to LT_(50) and LTmax of 41.5℃ and 46℃ *** results imply that it is crucial to consider how the GIFT strain performs under various environmental conditions and changes during ***,raising the GIFT strain of Nile tilapia in earthen ponds rich in phytoplankton and subject to protracted episodes of extreme hypoxia may have a detrimental physiological impact on its growth and welfare.
