TL;DR: In this article, the authors used ARIMA modeling and Fourier analysis to identify seasonal patterns from time series of monthly mean catch per unit effort of demersal species Lutjanus analis and two pelagic species.

TL;DR: In this paper, the performance of robust principal component analysis (RPCA), detrended correspondence analysis (DCA), and non-metric multidimensional scaling (NMDS) with two demersal fish data sets were assessed in terms of their stability to bootstrap-generated sample variation and the method's ability to reflect a well-known depth gradient.

TL;DR: In this paper, the taxonomic composition and biomass of seaweeds in the catches of 66 shrimp trawls sampled by observers at the fishing zones located north and south of the Magdalena river mouth, Colombian Caribbean, between July and September 2004.

TL;DR: In this article, the effect of mesh size and towing speed on the multispecies catch rates obtained in different demersal surveys carried out in the Colombian Caribbean Sea between 1988 and 2001, using two generalized linear models: one covering the entire study area and another restricted to one ecoregion.

TL;DR: In this article, a critical analysis of the current technological configuration of boats and fishing equipment for the industrial fleet of shrimp trawl fishing in the Caribbean Sea of Colombia, investigated the viability of introducing technological changes that would have a positive impact on efficiency of the fleet, currently embroiled in a situation of economic restraint due to the high operating costs.
