Metazoan parasite fauna of two peacock-bass cichlid fish in Brazil [PDF]

Check List, 2013
A parasitological study of two freshwater cichlid fish of the genus Cichla (C. kelberi and C. piquiti) from six different aquatic ecosystems in Brazil was performed. Based on the survey, a checklist of the component community of the metazoan parasites of

Reduced genetic diversity and the success of the invasive peacock bass (Cichliformes: Cichlidae) [PDF]

Brazilian Journal of Biology, 2021
Several species of Cichla successfully colonized lakes and reservoirs of Brazil, since the 1960’s, causing serious damage to local wildlife. In this study, 135 peacock bass were collected in a reservoir complex in order to identify if they represented a ...

Yield and centesimal characterization of collagen extracted from the skin of peacock bass Cichla monoculus [PDF]

Brazilian Journal of Biology
Fish processing provides waste of around 50.0% to 70.0% of the animal's initial weight, especially the skin. Thus, this residue contains the by-product that allows biopolymers to be obtained, highlighting collagen, which can be widely used in different ...

Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are ...

Future invasion risk assessment of the peacock bass in Neotropical ecoregions: A conceptual and testable model

Global Ecology and Conservation
Protecting freshwater biodiversity from non-native invasive species and their impacts is crucial for minimising both regional and global deterioration of ecosystem services. The yellow peacock bass Cichla ocellaris, a predatory freshwater fish endemic to

High trophic niche overlap between sympatric peacock basses (Cichliformes: Cichlidae: Cichla): Concordant findings from three dietary analysis methods. [PDF]

J Fish Biol
Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

A Femininomenon: Leadership Development Through Representation On-Screen. [PDF]

New Dir Stud Leadersh
ABSTRACT Historically, films and television centered men, but there has recently been a shift toward focusing on women and people of color (and women of color) in leading roles. Films and shows like Black Panther, Barbie, and Ashoka reflect this trend, offering more complex stories and diverse representation.

Reproductive cycle of the Neotropical cichlid yellow peacock bass Cichla kelberi: A novel pattern of testicular development [PDF]

Neotropical Ichthyology, 2013
The present study describes the testicular maturation phases (associating the germ cells development and the morphological changes suffered by the germinal epithelium along the whole year), and the testicular morphology in the yellow peacock bass Cichla ...

Brain morphology of native and invasive Cichla piquiti, the blue peacock bass (Cichliformes: Cichlidae), with ecomorphological insights

Neotropical Ichthyology
The central nervous system (CNS), composed of the encephalon and spinal cord, regulates physiological, motor, and cognitive processes in vertebrates. In Neotropical fishes, however, encephalon morphology and size remain poorly studied, particularly in ...

Estimation of peacock bass (Cichla spp.) mortality rate during catch-release fishing employing different post-capture procedures

Brazilian Journal of Biology, 2017
The effect of catch-and-release fishing on the survival of peacock bass (Cichla spp.) was evaluated by comparing two types of artificial bait (jig and shallow-diver plugs) and two types of post-catch confinement. Two experiments were conducted during the
