How do they test for mercury in fish?

Fish are collected by electrofishing then put on ice and transported to the laboratory. Then, researchers determine total length, weight and gender and a sample of muscle tissue is taken. The tissue samples are then labeled, frozen and shipped to the DEP Chemistry Laboratory in Tallahassee for analysis.

How do you collect aquatic invertebrates?

The simplest method of collecting insects from a stream or lake bottom is to just pick up some moderately sized rocks from a medium to fast riffle, or chunks of wood or small logs submerged near the lakeshore. If no rocks or wood are present then look for aquatic plants or plant debris, like decomposing leaves.

How do you preserve aquatic invertebrates?

Formalin is best for fixation, as it preserves internal characters better, followed by a rinse in fresh water before being placed in 70% ethanol. Flatworm preservation ideally requires not only meticulous care but also frozen formalin. Subsamples for DNA should be taken before relaxation, or taken from a second animal.
