Recorded movements of Panulirus argus tagged in sampling zones II-VI in Bahia de la Ascension, in 1985-86. Shaded areas denote 

 sampling zones; arrows indicate direction of movements and arrowheads the sites of recapture. Numbers indicate lobsters that moved 

 in each direction from denoted sampling zone. 



and 42 moved to areas nearer or at the outer reef (Fig. 

 10b). However, because no lobster fishing was con- 

 ducted in the inner half of the bay, no data have been 

 obtained to indicate the possible movement of lobsters 

 to that area. 



In the 1985-86 fishing season, eleven lobsters were 

 recaptured outside of the bay by fishermen of other 

 cooperatives. Of these, ten had traveled south, while 

 only one had gone north (Fig. 10). The longest straight- 

 line distance traveled by an animal was 45km. All the 

 recaptured lobsters that were tagged in 1986 were 

 caught in the fishing grounds of the cooperative 

 "Pescadores de Vigia Chico." The longest distance 

 traveled by any of these was 23km (Fig. lib). 



No animals were caught north of Boca Paila or south 

 of Punta Herrero (Fig. 10). However, fishing effort 

 immediately outside the bay was restricted to skin 

 diving on the reef to depths of about 15 m, so any 

 lobsters that moved beyond that depth would not be 

 recaptured. 



Reproduction 



During the 1985 tagging program, only four individuals 

 (67.2, 82.5, 83.7, and 116.8mm CL) of 1819 females had 

 spermatophores attached, and only one individual 

 (76.0mm CL) carried eggs. In the 1986 program, five 

 individuals (87.0, 90.2, 94.2, 94.9, and 100.3mm CL)
