Martínez-Viloria,Héctor Manuel; Franke-Ante,Rebeca; Narváez Barandica,Juan Carlos; De La Hoz Maestre,Javier.
ABSTRACT With the purpose of evaluating the status of the lane snapper Lutjanus synagris from limited catch length data from the landings of artisanal fishing catches recorded between 2006 and 2012 in Tayrona and Corales del Rosario y de San Bernardo National Parks, and the Vía Parque Isla de Salamanca, simple indicators and the decision tree methodology were applied. it was observed that this indicator mostly configured a selectivity pattern represented in capture of mayoritary immature specimens (<L mat ) and a spawning biomass level lower than the target reference point, affecting the natural renewal of L. synagris stocks. Also, it was ratified the degree of overfishing for growth and recruitment to which L. synagris is subjected. Reducing pressure...

Tette-Pomarico,Aliano; López-Peña,Arístides; Franke-Ante,Rebeca; Duarte,Luis Orlando.
ABSTRACT The neotropical cormorant (Nannopterum brasilianus) is a piscivorous bird with colonial nesting. It is distributed from southern North America to Argentina. The largest colony of N. brasilianus in Colombia is located in the locality of Punta Blanca, in the Flora and Fauna Sanctuary Ciénaga Grande de Santa Marta (FFS CGSM), in the lagoon complex with same name (LC CGSM). The diet and niche width of N. brasilianus were analyzed from pellets collected on the western edge of the Punta Blanca nesting colony during the breeding season of 2017. Prey identification was based on mainly on the morphology of the fish otoliths found in these pellets (n = 64). There were eight fish species identified in the diet of N. brasilianus of which three are new records...
