Objectives

1. To determine the optimal composting conditions for the starfish waste
2. To determine the effect of composting on the saponin toxin present in the starfish
3. To determine levels of faecal coliforms and heavy metals folowing composting
4. To assess the nutrient value and electrical conductivity (salinity) of the resultant compost
5. To demonstrate the effect of the resultant composts on the growth of two plants (lettuces anf radishes) in a glasshouse trials

SCRC: RTG:To learn practical skills in conducting viral disease challenge techniques in Penaeid prawn species using white-spot syndrome virus (WSSV) as a model virus to be conducted at Shrimp Biotechnology Business Unit (BIOTEC), Pathumthani, Thailand.

Due to the nature of commercial prawn farming, constraints within the industry such as disease management will always pose problems from managing endemic diseases; such as gill-associated virus in Australia, to exotic diseases including Yellow Head Virus and White Spot Syndrome Virus. The need to...
