| The coastline extended between Manzanillo city and the mouth of Cauto River is a widely man-modified region by the urban-industrial-fishing activities. The present study in shows the results obtained in this zone on summer 2002, May and November 2007 and November 2008. Conditions of sediments and tenors was analyzes, starting from the effects of insecticide and other contaminant compounds, either of organic or inorganic nature, and also exposes the decreasing tendency in the production of species of economic interest, like the blank shrimp (Litopenaeus schmitti), pink shrimp (Farfantepenaeus notialis) and oyster (Cras sostrea rhizophorae). The negative relationship between the shrimp’s capture and water dam volumes was demonstrated and explained, with 0.81... |

| Several grenadier species distribute in the SW Atlantic Ocean. Macrourus carinatus and Caelorinchus fasciatus are more frequently identified in commercial catches and during research cruises. Those benthopelagic fishes, related to subantarctic waters, inhabit at depths beyond 200 m and in high seas, between 36º S-59º S. During the surveys carried out on board of Argentinean research vessels, M. carinatus was present in 4% of the trawls performed. The highest densities (>17 t nm-2), obtained between 360-380 m depth, at 39º S, decreased significantly southwards. C. fasciatus was caught in 6% of the total trawls and the highest densities (15-35 t nm-2) were found at depths beyond 200 m, south of 52º S. Due to the difficulty encountered to identify them, in... |
