The synonymy of Haplochromis pharyngalis and Haplochromis petronius (Cichlidae).

Journal of Fish Biology, 2020
Haplochromis pharyngalis and H. petronius, two endemic cichlids from the Lake Edward system (Uganda, DR Congo), are very similar in general morphology, but have been reported to differ in pharyngeal jaw morphology and distribution.

The hemoglobin of Geophagus brasiliensis (cichlidae)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1991
Abstract 1. 1. The hemoglobin of Geophagus brasiliensis was submitted to electrophoresis on starch gel and agar-starch on microscopic slides. In both supporting media five major components were observed. 2. 2. Stripped hemoglobin showed normal Bohr shift (Δlog p 50 /Δ pH = θ = −0.661 ).

Cytotaxonomy of 41 Species of Neotropical Cichlidae

Copeia, 1979
Chromosome morphology for 40 species and diploid counts for 41 species of neotropical Cichlidae were prepared using colchicine treated gill epithelial squashes. Gross chromosomal evolution among this group appears to have been somewhat conservative with the majority of the species retaining the putative ancestral diploid number of 48.

The Reproductive Behaviour of Aequidens paraguayensis (Pisces, Cichlidae)

Zeitschrift für Tierpsychologie, 1975
AbstractThe reproductive behaviour of aquarium‐held Aequidens paraguayensis is described, with emphasis on a quantitative comparison of male‐female parental roles. It is a biparental species. Eggs, laid on leaf litter, are guarded and aerated for about 32 hours (25–27° C) and newly‐hatched young are orally brooded for several days. Both sexes performed

The cost of parental care inHaplochromis ‘argens’ (Cichlidae)

Environmental Biology of Fishes, 1994
The cost of parental care in the maternal, mouthbrooding cichlid,Haplochromis ‘argens’ was measured in terms of parental survival, fecundity and breeding frequency. In comparison with non-parental females, those that mouthbrooded eggs for a period of 16 days took 33 % longer to respawn. Parental females also grew more slowly between spawnings, and this

Adaptations to feeding in herbivorous fish (Cyprinidae and Cichlidae).

2005
AbstractThis chapter describes the anatomical and behavioural adaptations of herbivorous cyprinids and cichlids for feeding on plants, including phytoplankton, algae, periphyton, macrophytes, seeds and detritus.
