Creran’s waters are monitored for shellfish purposes from two sites, one near the mouth and one near the head of the main basin. In addition the river Creran is sometimes sampled for nutrients above its discharge into the upper basin: concentrations are typically low, as might be expected in runoff from granitic rocks and unimproved acidic grassland. SEPA (2004) reports that: In 2002, all samples from both monitoring sites met all shellfish waters imperative and guideline environmental quality standards.
EQS) Conditions consistent with the achievement of the values specified… for the biological quality elements [at moderate status]. definitions of ecological and physico-chemical status. In essence, the ecological status of a water body is high when its phytoplankton, seaweeds or seagrasses, and benthos, all appear to be in a natural condition. 5 is a flow diagram to show how a regulator might apply the Directive. The starting point is the definition of water bodies and the identification of the type to which each belongs; then the present quality status of each water body identified in relation to a “type-specific reference condition” as high (the same as a water body in the reference condition), good (acceptable), moderate, poor, or bad.

In high densities the mussels bind the substratum and provide a habitat for many species more commonly found on rocky shores; the mussels are usually encrusted with barnacles and whelks and small crabs are common amongst the mussels.
