Bioacoustic characterization of mating calls of a freshwater fish (Prochilodus magdalenae) for passive acoustic monitoring

Biota Colombiana, 2021
Fish produce sounds that are usually species-specific and associated with particular behaviors and contexts. Acoustic characterization enables the use of sounds as natural acoustic labels for species identification.

Preliminary evaluation of bocachico (Prochilodus magdalenae) fecundity in the Sinú River, Colombia.

Revista MVZ Córdoba, 2017
El Bocachico (Prochilodus magdalenae) es la principal especie de la pesquería en las cuencas de los ríos Magdalena y Sinú, debido a su gran aceptación y valor comercial en Colombia. Entre abril y junio de 2000, se recolectaron 44 ejemplares entre Lorica y Tierralta, con tallas entre 19.4 y 28.2 cm de longitud estándar (LS) y 24.6 y 35.0 cm de longitud ...

Zootechnical Parameters and Enzyme Activity in the Species Brycon moorei (Steindachner 1878)

Fishes, 2023
Brycon moorei is an opportunistic omnivorous species. It is not known what its nutritional requirements are at any stage of its development; this study determined the influence of diet on the zootechnical parameters and enzyme activity of these fish.

Border Collision Bifurcations in a Generalized Model of Population Dynamics

Discrete Dynamics in Nature and Society, Volume 2016, Issue 1, 2016., 2016
We analyze the dynamics of a generalized discrete time population model of a two‐stage species with recruitment and capture. This generalization, which is inspired by other approaches and real data that one can find in literature, consists in considering no restriction for the value of the two key parameters appearing in the model, that is, the natural

Ecological Factors and Diversification among Neotropical Characiforms

International Journal of Ecology, Volume 2012, Issue 1, 2012., 2012
Morphological and DNA sequence data has been used to propose hypotheses of relationships within the Characiformes with minimal comparative discussion of causes underpinning the major intraordinal diversification patterns. We explore potential primary morphological factors controlling the early diversification process in some Neotropical characiforms as

Dams effects on potamodromous Prochilodus magdalenae: evidence from endocrine response

, 2017
Background. Prochilodus magdalenae is a neotropical fish that synchronizes reproduction with flood river pulses. Methods. We used an endocrine method to test the influence of hydropeaking on hormone production related with reproduction. We analyzed P. magdalenae reproduction in individuals from two sectors of a Neotropical river basin: one with

Desempeño de bocachico Prochilodus magdalenae en sistemas intensivos de producción con tecnología biofloc

Biotecnoloía en el Sector Agropecuario y Agroindustrial, 2018
RESUMEN La Tecnología BioFloc (BFT) se caracteriza por altas densidades, bajo consumo de agua y espacios reducidos; sin embargo, son escasos los estudios adaptando esta tecnología a especies nativas como bocachico Prochilodus magdalenae. El estudio evaluó el desempeño zootécnico del cultivo con BFT a tres densidades en fase de pre-engorde: 5(T1), 10(T2)

Áreas de reproducción de peces migratorios en la cuenca alta del río Magdalena, Colombia

Biota Colombiana, 2014
During the 2011-2012 hydrological cycle, weekly samples were taken to evaluate the reproduction of migratory fishes in the area of influence of the El Quimbo hydroelectric project. This analysis considered the abundance and density of individuals in each
