Arsenic is one of the most important heavy metals causing disquiet from both ecological and individual health standpoints (Hughes et al., 1988).It has a semimetallic property, is prominently toxic and carcinogenic, and is extensively available in the form of oxides or sulfides or as a salt of iron, sodium, calcium, copper, etc. Crayfish Dissection Objectives: • Describe the appearance of various organs found in a crayfish. Avoiding, or at least minimising reproduction in grow-out ponds is important in effective management. Crayfish, Procambarus clarkii, effects on initial stages of rice growth in the lower Mondego River Valley (Portugal).

Inferential statistics are used to determine the probability of chance alone leading to your sampled results. Tasmanian giant freshwater crayfish have extremely slow maturation rates, with females reaching sexual maturity at approximately 14 years of age, a weight of 550 grams (19 oz) and a carapace length of 120 millimetres (4.7 in).
