Poecilia reticulata is a freshwater fish from the northeastern part of South America and spread widely to various countries in Asia and other continents. However, research about P. reticulate is limited even though it is a well-known fish... more
BACKGROUND & OBJECTIVES The predatory potential of the larvivorous fishes can be affected by the presence of alternative preys. In the present study the predation pattern of the sewage dwelling Poecilia reticulata (Peters 1872) on the... more
In the branchial mitochondrion-rich (MR) cells of euryhaline teleosts, the Na+/K+/2Cl− cotransporter (NKCC) is an important membrane protein that maintains the internal Cl− concentration, and the branchial Na+/K+-ATPase (NKA) is crucial... more
Genetic linkage maps of the guppy (Poecilia reticulata) were constructed from independent crosses between the Tuxedo strain and a feral line (Wildtype). Segregation patterns of random amplified polymorphic DNA (RAPD) markers and... more
Inbred lines are an important tool of genetic studies of all traits, including behavior. Independently derived strains of ornamental "designer" guppies are readily available and predicted to be inbred; however, little is known about... more
Understanding and working with the primary trait found in IFGA Gold Class Domestic Guppies; Metal Gold (Mg).
Traditional compounds used to treat fish diseases in aquaculture and the ornamental fish industry (such as formalin and malachite green) can be more toxic to the hosts than their parasites. With the reviviscence in the use of herbal... more
Evidence on the effectiveness of low-cost, sustainable, biological vector-control tools for the Aedes mosquitoes is limited. Therefore, the purpose of this trial is to estimate the impact of guppy fish (guppies), in combination with the... more
A distinction should be made between Pink (Pk) in genetoype and pink coloration in modern Domestic Guppy strains.
Likely one of the least appreciated guppy phenotypes to be found is Homozygous Asian Blau (Ab). Such fish are normally considered weak by-products of popular delta breedings involving blue iridophores and red color pigment; Blue Topaz,... more
41 Ambient exposure to a short synthetic peptide has enhanced fecundity (number of offspring) in 42 invertebrates and vertebrates, ostensibly by disinhibiting reproduction. In separate experiments 43 nematodes (Caenorhabditis elegans) and... more
Replicated ecological gradients are prime systems to study processes of molecular evolution underlying ecological divergence. Here, we investigated the repeated adaptation of the neotropical fish Poecilia mexicana to habitats containing... more
The interest in the ecological relevance of risk assessments and, thus, in in situ bioassays has been increasing in the last years. The present study developed a time- and cost-effective in situ bioassay, aiming at obtaining, in a short... more
...alot of the misconceptions in Guppy Genetics by hobbyists are based on observations derived from the wrong starting point.
Variation in mating preferences coupled with selective predation may allow for the maintenance of alternative mating strategies. Males of the South American live-bearing fish Poecilia parae fall in one of five discrete morphs: red,... more
