<p><font size=3>This paper applies a bioeconomic model in order to study
different interactions between a harvested renewable resource and a non-renewable
resource without commercial value that is negatively affected by the harvesting
activity. This enables the analysis of for instance cold water coral habitats
and their importance to commercial fish species. The fish is harvested
either in a manner that does not damage coral, such as stationary gear,
or in a destructive fashion, such as bottom trawling. We find that when
coral is a <i>preferred</i> or<i> essential</i> habitat, the optimal steady-state
fish stock is no longer independent of the habitat level, i.e. <i>optimum
optimorum</i> values determine the optimal stationary gear harvest rate
and how much habitat should optimally be preserved. Such <i>optimum optimorum</i>
values will vary according to the type of habitat-fishery connection, and
some bottom trawling may be optimal for some periods of time. Our findings
extend upon the underlying assumption of a constant habitat quality of
bioeconomic models when destructive fishing methods are involved and a
habitat-fishery connection exists. </font><font size=1><br>
