coverage of the Chilean-Peruvian coast between Antofagasta (Chile) and Paracas-Pisco (Peru). In 

 Ecuador, Bahia de Caraquez replaced Esmeraldas. 



As in the previous missions, replicate sampling was attempted at more than one station, 

 usually a few hundreds meters apart, per site. Total wet weight tissue per station was between 200 

 to 300 grams. Photographs of the locations /stations were taken to document the area for further 

 sampling efforts. Shell samples from each location were kept for a later confirmation/identification 

 of the species. Frozen samples were transferred to San Jose\ Costa Rica. 

 BRAZIL 



Santos (03/16/92). Santos is a coastal port city located about 90 km from Sao Paulo. Duplicate 

 samples (Perna perna) were collected from 3 different stations along the main ship channel. 

 Access to the site is by car from Sao Paulo and by boat to the sampling stations. 

 Contamination:: A large number of industries (chemical industries, oil refineries, etc.) discharge 

 their wastes either directly into the bay or into the Cubatao river. This river discharges in the upper 

 part of the Bay of Santos. 



Salvador (03/18/92). The sampling site is located about 95 km from Salvador. Samples of 3 

 different bivalves were collected at one station during low tide. Mussels (Mytela guayanensis) 

 were collected from within the mangroves, oysters (Crassostrea rizhophorae) were collected from 

 nearby underwater constructions and Anomalocardia brasiliana were found in the sandy inter tidal 

 area. Access to the site is by car from Salvador. 



Contamination:: Effluents from paper mills are discharged into this area. Domestic effluents. 

 Several small creeks. 



Recife (03/20/92). Oyster and mussel samples were collected from 3 stations in Pina Bay. 

 Oysters (Crassostrea rizhophorae) were collected from inter tidal populations during low tide. 

 Mussels (Mytellafalcata) were collected from beds on the mud (0.5-1.0 water depth during low 

 tide). The site is located within city limits. 



Contamination:: Several rivers (Jordao, Tejipio and Jiquia) run through the city of Recife and 

 discharge into the Pina river before reaching the Pina Bay. Industrial and domestic effluents. Port 

 activities. Cholera 



Lagoa Mundau/Macei6 (03/21/92). Maceid is located about 200 km south of Recife. This area 

 was sampled instead of a pre-selected site near Aracaju because of its importance as a mussel- 

 producing area for human consumption in Brazil. Mussel (Mytellafalcata) samples were collected 

 by hand from beds on the soft bottom by local fishermen working in the lagoon. 

 Contamination:: Limited water exchange with the open sea. Domestic effluents directly discharged 

 in channels empty into the lagoon. Cholera. 



Fortaleza (03/23/92). Two different sites were sampled in Fortaleza. The first location is a fairly 

 small rocky formation about 400-500 meters long in front of the city. Two duplicate oyster
