Simple Summary: Paradise fish (Macropodus opercularis) has been a favored subject of behavioral research during the last decades of the 20th century. Lately, however, with a massively expanding genetic toolkit and a well annotated, fully sequenced genome, zebrafish (Danio rerio) became a central model of recent behavioral research. But, as the zebrafish behavioral repertoire is less complex than that of the paradise fish, the focus on zebrafish is a compromise. With the advent of novel methodologies, we think it is time to bring back paradise fish and develop it into a modern model of Citation: Rácz, A.; Adorján, G.; behavioral and evolutionary developmental biology (evo-devo) studies. The first step is to define the Fodor, E.; Sellyei, B.; Tolba, M.; housing and husbandry conditions that can make a paradise fish a relevant and trustworthy model.

  • Analysis of the Diet Between an Invasive and Native Fishes in the Peruvian Amazon. Anthony Mazeroll [email protected] Introduct
    Analysis of the diet between an invasive and native fishes in the Peruvian Amazon. Anthony Mazeroll [email protected] Introduction Non-native species are the second greatest threat to global species biodiversity after land development (Vitousek, D'Antonio, Loope, Rejmanek, & Westbrooks, 1997). Due to the magnitude of this threat, it is vital that the impacts of exotic species are understood. Fish biodiversity is especially threatened by the ecological changes caused by non-native species (Gozlan, Britton, Cowx, & Copp, 2010). Having higher species diversity allows more ecological processes to take place, protecting the resources of that system, and making it more resilient to change (Folke, 2006). Adding outside inputs, such as additional non-native species, into an ecosystem can have beneficial or compromising effects depending on the amount and type. Invasive species have been shown to reduce native species richness and diversity of native organisms. Some have argued that the transportation of species from one ecosystem to another is actually beneficial for diversity, and non-native species are not really an environmental “problem”. Introductions of non-native species increase diversity at a local level because in the short term there will be a lag time where both non-native and natives can coexist (Lodge, Stein, Brown, Covich, Bronmark, Garvey and Klosiewski, 1998). Species entering a new ecosystem have to pass through a gauntlet of barriers before they can become established. The usual progression of invasion is: transportation to the new ecosystem, initial establishment, spread to a larger region, and then naturalization into the new community (Marchetti, Light, Moyle, and Viers, 2004).

  • The Pharyngeal Organ in the Buccal Cavity of the Male Siamese Fighting Fish, Betta Splendens, Supplies Mucus for Building Bubble Nests
    ZOOLOGICAL SCIENCE 27: 861–866 (2010) © 2010 Zoological Society of Japan The Pharyngeal Organ in the Buccal Cavity of the Male Siamese Fighting Fish, Betta splendens, Supplies Mucus for Building Bubble Nests Chao-Kai Kang and Tsung-Han Lee* Department of Life Sciences, National Chung-Hsing University, 250, Kuo-Kuang Road, Taichung, 402 Taiwan The male Siamese fighting fish, Betta splendens, builds a bubble nest on the water surface to care for offspring during the reproductive period. To our knowledge, this study is the first to determine the composition of the bubble nest and to compare the pharyngeal organs of male and female Siamese fighting fish to determine the relationship between the pharyngeal organ and the ability to make bubble nests. Dot blots of the bubble nest probed with periodic acid-Schiff’s (PAS) staining and Ponceau S solution revealed that the contents of the nest are glycoprotein rich. Dissection of the heads of Siamese fighting fish showed that the pharyngeal organ is located in the position through which inhaled air passes. The epithelial structure of the pharyngeal organ of the Siamese fighting fish, like that of other teleosts, has numerous wrinkles and papillae. Mucous goblet cells were observed on the epithelium of pharyngeal organs in male and female fish. The pharyngeal organ was found to be larger in male than in female fish. In addition, the epithelium of the pharyn- geal organ in male fish has a greater number of mucous goblet cells than that in female fish. In Siamese fighting fish, this sexual dimorphism of the pharyngeal organ suggests that the male fish secretes more glycoprotein-rich mucus to build the bubble nest.

  • The Effect of Bubble Nest Size on Sexual Selection in Wild Siamese Fighting Fish
    SHORT COMMUNICATION The effect of bubble nest size on sexual selection in wild Siamese fighting fish Mullica Jaroensutasinee1 and Krisanadej Jaroensutasinee2 Abstract Jaroensutasinee, M. and Jaroensutasinee, K. The effect of bubble nest size on sexual selection in wild Siamese fighting fish Songklanakarin J. Sci. Technol., 2003, 25(2) : 267-273 The effect of bubble nest size was tested on male contest and female preference in wild Siamese fight- ing fish, Betta splendens Regan, a sexually dimorphic fish that exhibits paternal care. Females presented with two potential mates of different bubble nest areas did not prefer larger bubble nest males. Larger bubble nest males were not more successful in male contests. There were no differences in fighting duration. Comparing agonistic behaviour between large and small bubble nest males, there were no differences between these two males concerning any agonistic behaviours during fighting.
