| Seasonal variation of food items of Bairdiella ronchus (Cuvier, 1830) classified by size was analysed based on monthly samples between september/1993 and september/1996 at the Guaratuba Bay, Southern Brazil. The stomach contents of a hundred eighty-two fishes were analysed by the Occunence Frequency Method and Point Count for a Lot Method. The individuais were divided in two groups, smaller and longer than 140mm, and a comparative study of digestive tract and branchial are was performed for these groups. For fishes smaller than 140mm the following sequence of items was obtained matching both methods by using the Preponderance índices: decapods (subdivided in Brachyura, Caridea and Penaeidea), polychaets, isopods, fishes, unidentified material, copepods,... |

| Seasonal variation of the food items of the "bagre-urutu", Genidens genidens is analysed based on monthly samples between September, 1993 and April, 1995 at the Guaratuba Bay, coast of Paraná. The stomach contents of 105 fish is analysed by the Occurrence Frequency Method and 41 of these have also been analysed by the Volumetric Method. Matching both methods using the Preponderance índices, a larger incidence of decapods is determined, followed by other crustaceans, molluscs, polychaets, fish, and plant material. The data show the existence of a strong seasonal variation in the diet. |

| The present work aimed to evaluate the contamination of Escherichia coli in the surface waters and oysters from two cultivations of Guaratuba Bay and to analyze the correlation patterns among the concentrations of E. coli in the waters and in the oysters with the local physical-chemical parameters. Samples were collected in the spring of 2007 and summer, autumn and winter of 2008 from two points of the bay (internal point and external point). From each cultivation and sampling period, 18 oysters were collected. The samples of surface water were collected for the measurement of physical-chemical parameters (pH, salinity, temperature, dissolved oxygen, seston, particulate organic matter) and quantification of E. coli. The surface water analyzed in the summer... |

| Reproductive and biometrical analyses were pertormed on 1629 individuals of P. corvinaeformis collected monthly from October 1993 to September 1996, at Guaratuba Bay, Southern Brazilian coast. The results indicate that the species is more abundant in the mangrove area during winter, when the largest individuais were collected, and spring, when the water temperature is lower and the salinity higher than summer or autumn. The relationship of body weight to body length, for grouped sexes, is "lnTW= -12,0456 + 3,1831 lnTL". The monthly Condition Factor is highest during summer and lowest during winter. It is suggested that P. corvinaeformis is present in the mangrove area during a specific etape of its life cycle and does not use this area to maturation and... |

| The species of Citharichthys Bleeker, 1862, C. arenaceus Evermann & Marsh, 1900 and C. spilopterus Günther, 1862, are the most common flatfishes found in Guaratuba Bay, south Brazil. Different size categories of these flatfish occur in the mangrove area throughout the year. The Gonadosomatic Index, the Condition Factor, and the morphological analyses of the gonads from samples obtained between 1994 and 1996 reveals a spawning activity during late Spring and early Summer. This period coincides with the increase in temperature and decrease in salinity. Spawning evidence and the presence of ali size categories throughout the year indicate that Citharichthys spp. are permanent inhabitants of the mangrove in Guaratuba Bay, where they complete their life... |
