| Cetengraulis edentulus is a broadely distributed engraulid in Southwest Atlantic, currently accounting for the main fish species commercially exploited at Guanabara Bay, Brazil. This study aimed to extend the knowledge on reproduction of C. edentulus at Guanabara Bay and to test whether some descriptors of reproductive activity, especially the gonadosomatic index (GSI), and the index of reproductive activity (IRA) changed among seasons. A total of 978 C. edentulus specimens were retrieved from purse seine commercial landings at Conservas Rubi S.A. company, in São Gonçalo city, RJ. Subsamples of 90-120 individuals were collected from bimonthly yields between July 2010 (winter) and June 2011 (autumn). Most fish were adults (120-170 mm TL), in response to the... |

| The use of artificial structures as a shelter for fishes was evaluated aiming to assess increase in fish abundance in Ilha Grande Bay at Southeast Brazilian coast (Lat: 22°8'-23°5' S; Long. 44º05-44º40W). Five different types of structures, made of clay tiles, with an increase range on size and complexity were tested to assess their efficiency. Fish were counted in each type of structure from May-1996 to April-1997 by underwater observation made with snorkelling. According to the pattern of concentration in the structures, two groups of fishes were identified. One comprised by E. guaza, M. rubra, R. randalli, S. hispidus, Sphoeroides sp and Haemulun sp showed affinity for hard bottom, irregular profile and an increase in abundance on the more complex and... |
