Abstract

Two experiments were carried out in the research farm of An Giang University. The first experiment was a study on the growth performance of Marble goby and Tra catfish fed diets of trash fish and rice field prawns replaced (on an iso-nitrogenous basis) with 0, 25, 50, 75 and 100% of frozen earthworms (Perionyx excavates).

The weight gains of Marble goby and Tra catfish, and the survival rate in the Marble Goby, decreased markedly with curvilinear trends as the proportion of frozen earthworms in the diet was increased (Experiment 1). The Tra catfish appeared to adapt better than the Marble goby to the frozen worms.  The second experiment, which was designed to test the hypothesis  that the poor growth rates with frozen earthworms was due to the low palatability of the earthworms after being frozen, confirmed the negative effects of this method of conservation. Growth rates were 4 and 2 times greater for Marble goby and Tra catfish, respectively,  when they were fed fresh rather than frozen earthworms.  Survival rate was 100% on the fresh earthworm diet.

    What earthworm can not eat?

    If you’re looking for another reason to eat fresh and eat healthy, this may be it! Worms can eat pretty much any organic matter that was once living, which encompasses a lot of healthy food such as fruits, vegetables and grains!
