| From January to December 1995, 332 individuals of the Callinectes ornatus species were collected from the Itapocoroy inlet in Penha, Sta. Catarina, Brazil to study its natural diet and the seasonal variations of diet. Results showed a diversified trophic spectrum with a generalized dietary strategy comprising the algae, macrophyta, foraminiferida, mollusca, polychaeta, crustacea, echinodermata, Osteichthyes and NIOM (Nonidentified Organic Matter) groups. |

| Xiphopenaeus kroyeri is the most exploited shrimp specie along Center-South coast of Santa Catarina State, Brazil, by artisanal fishery. In the period from March/1996 to February/1997, 3965 shrimps were collected (1843 males and 2122 females) sampled by over-trawl, with the depth oscillating between 5 and 15 meters. Xiphopenaeus kroyeri shows seasonal fluctuations in its abundance with higher rates in autumn. The population's average total-length varied between 7.5cm and 9.1cm, and the presence of juveniles was common along the year. The males and females get to the first gonadal maturation with 7.4 cm and 9.0 cm length, respectively; these lengths were reached within 6 and 8 months of age. |

| In the period of January and December, 1995, there were collected by means of overtrawl, 12977 samples of macroinvertebrates and demersal fishes, in the Armação do Itapocoroy, Penha (SC), between the depths of 6 to 10 meters, in the periods of morning, afternoon, and evening. There were registered the incidence of 57 families, 80 kinds and 92 species distributed between the macroinvertebrates and demersal fishes. The families of greater incidence were: Portunidae (30.7%), Strombidae (11.4%), Sciaenidae (11.1%) and Bothidae (10.3%) which all together, contributed with 63.5% of the total samples. The grouping analysis presented greater diversity in the Winter (2.77) and smaller one in the Springtime (1,34); the amplitude of variation H' reflects the great... |
