b. Recruitment is declining (the danger point 

 cannot be precisely quantified).

 (the acceptable level of CPDE is a subjective 

 economic-esthetic judgement). 



d. A change in target species because of a scarcity of 

 the original target. 



Socio-Economic 



a. Conflicts among user groups (may vary seasonally, 

 during the week, etc.). 



b. The real value of the fishery (i.e., adjusted for

d. Change in the proportion of the total harvest taken 

 by various user groups. 



e. Significant increases in participation which may 

 signal impending overcapitalization. 



f. Request for special management zones for artificial reefs. 



Environmental 



a. Physical degradation of the habitat. 



b. Biological degradation of the habit (e.g., diseases, 

 predators). 



c. Chemical degradation of the habitat. 



d. Decline in species diversity. 



A. Zoning for Artificial Peefs or Fish Havens 



Upon request from the permittee (i.e., holder of COE permit) for 

 any artificial reef or other modification of habitat for the purpose of 

 influencing fishing or fishes, the Council may, after due consideration and 

 within the constraints of the National Standards of FCMA and this plan, 

 designate the modified area and an appropriate surrounding area as a special 

 management zone and recommend that the Secretary promulgate regulations 

 which will further the purposes for which the permittee modified the habit.
