The Influence Of Temperature And PH On The Rate Of Oxygen Consumption Of The Freshwater Subterrestrial Crab Sudanonautes Aubryi From Okigwe, Imo State:- Nwankwo, Enyinnaya L
ABSTRACT
Factors affecting the metabolic
rate of invertebrates can be either environmental or endogenous. The
environmental factors include temperature, salinity, hydrogen ion
concentration, photoperiod and oxygen availability. While the endogenous
factors may include the body size, respiratory surfaces, activity, nutritional
conditions, and state of reproductive cycle (Newell et al, 1979). These
environmental physico-chemical factors will affect the life patterns and
activities of these animals. Thus, information about the metabolic rates,
generally determined by measuring, the oxygen consumption (Q) , is of basic
importance in defining the energy, budget of such animals. Such knowledge can
be essential for the establishment of fishery facilities, such as long term
confinement of animals and for the evaluation of the ao^aculture perspectives
of the species involved Buesa (1979). The relation between oxygen consumption
(Q) and the unit body weight oxygen consumption (QW" ) is a well
documented phenomenon in the animal kingdom and is most evident in animals
weighing from 1 to 1000 giams and metabolism in poikilotherms generally varies
directly with the environmental temperature Wolve-Kamp and Waterman (1960). In
the Kelp cxab Pu^ethn • -——Uc -for instance, 96% o£ varience in Q was as a
result of size. So for strict quantitative purposes metabolic rate as defined
by rate of oxygen consumption are satisfactory only when individuals of one
specie and of about the same size are compared Wolvekamp and Waterman (1960).
Since relatively little information is available on the large crustaceans, this
study is aimed at investigating some of the factors that affect the metabolic
rate of the fresh water subterrestrial crab Sudanonautes aubryi. This work is
centred on two environmental factors: temperature and hydrogen ion
concentration (pH).
