| ABSTRACT This study presents the density, taxonomic composition, spatial and temporal distribution of fish larvae in the Gulf of Guayaquil, as well as the relationship with some physical-chemical variables. Samples were collected at 16 stations, taken in the first nautical mile of the external and internal estuary of the gulf, located in front of the province of Guayas and northwest of the island of Puná, during June to December 2012. Surface trawls were carried out with a simple conical network (mesh eye: 300 μm; mouth diameter: 0.3 m; length: 1.2 m). Temperature, salinity, and transparency were measured before each drag. Significant differences were detected between zones, registering higher temperatures, lower salinity, and transparency in the interior... |

| Spatial variability in the concentration of total bacteria, saprophytes and coliforms abundance was investigated in surface waters of Paranaguá and Antonina Bays. Six points along a profile from the entrance of Paranaguá Bay to the innermost part of Antonina Bay, were sampled on February 26, 1997. Temperature, salinity, dissolved oxygen, pH, particulate organic carbon, water transparency and seston were also measured. Determination of total bacterial abundance and biomass were made with the epifluorescent method. Saprophytic bacteria counts were conducted with ZoBell 2216E culture medium with fresh and 32 water and the coliform MPN was enumerated with the chromogenic substrate method. Principal component analysis of biotic and abiotic data showed a... |
