EFFECT OF DIETARY CASSAVA MEAL ON GROWTH OF MUD CRAB, Scylla paramamosain
Abstract: It is widely
recognized that a major constraint to development of a mud crab aquaculture
industry is the availability and formulation nutritionally adequate but
relatively low cost diets. Development of artificial diets, which seek to
minimize inclusion of expensive feed ingredients such as fish and terrestrial
meals, is considered to be a priority for improving the profitability of this
emerging industry. Typically, carbohydrates such as starches are relatively
cheap and therefore offer opportunity to supply dietary energy at low cost. The
study examines the capacity of mud crab, Scylla paramamosain to utilize a range
of dietary cassava meal as carbohydrate source. Four levels of cassava meal
were used at inclusion levels of 0%, 10%, 20%, and 30% in diets. Mud crabs will
readily accept the diet containing relatively high levels of cassava meal. This
experiment proved that mud crab which fed 10% dietary cassava meal gains weight
more than the one fed diet without dietary cassava meal. The increasing level
of cassava meal to more than10% in diet reduced final weight and weight gain.
To some extent, mud crab, Scylla paramamosain is capable to use dietary
carbohydrate from cassava meal. The finding raises the possibility to include
10% cassava meal in formulation low cost diet for mud crab.
