Given the additional economic groups, while other farms produce a wide spectrum of effects of tropical fish trade such as support industries, aquatic livestock. wholesalers, retail pet stores, and aquarium product manufacturing, the importance to Florida is tremendous.

Abstract Annual fishes are found in both Africa and South America occupying ephemeral ponds that dried seasonally. Neotropical annual fishes are members of the family Rivulidae that consist of both annual and non-annual fishes. Annual species are characterized by a prolonged embryonic development and a relatively short adult life. Males and females show striking sexual dimorphisms, complex courtship, and mating behaviors. The prolonged embryonic stage has several traits including embryos that are resistant to desiccation and undergo up to three reversible developmental arrests until hatching. These unique developmental adaptations are closely related to the annual fish life cycle and are the key to the survival of the species.

  • Taxonomy of the Seasonal Killifish Genus Neofundulus in the Brazilian Pantanal (Cyprinodontiformes: Rivulidae)
    65 (1): 15 – 25 © Senckenberg Gesellschaft für Naturforschung, 2015. 4.5.2015 Taxonomy of the seasonal killifish genus Neofundulus in the Brazilian Pantanal (Cyprinodontiformes: Rivulidae) Wilson J.E.M. Costa Laboratory of Systematics and Evolution of Teleost Fishes, Institute of Biology, Federal University of Rio de Janeiro, Caixa Postal 68049, CEP 21944-970, Rio de Janeiro, Brasil; wcosta(at)acd.ufrj.br Accepted 19.ii.2015. Published online at www.senckenberg.de / vertebrate-zoology on 4.v.2014. Abstract On the basis of fish collections made between 1991 and 2014, four species of the seasonal killifish genusNeofundulus are reported to occur in the Brazilian Pantanal, Paraguay river basin: N. parvipinnis, endemic to the Cuiabá and São Lourenço river drainages, in the northern portion of the Pantanal; N. rubrofasciatus, new species, from the Miranda river drainage, N. aureomaculatus, new species, from the Aqui- dauana river drainage, both in the south-eastern portion of the Pantanal; and N. paraguayensis, occurring in the Paraguay and Nabileque river floodplains, in the southern part of the Pantanal. The new species are diagnosed by unique colour patterns, and a combination of morphological characters states indicating that they are more closely related to N. parvipinnis and N. splendidus than to N. paraguayensis. Key words Aplocheiloid killifishes, Biodiversity, Pantanal wetland, Paraguay river, Systematics. Introduction The Brazilian Pantanal, also known as Pantanal de Mato Neofundulus has been known for a few papers in Grosso, is a vast wetland region, about 140,000 km2, the scientific literature. Until 1988, knowledge about comprising a tectonic depression along the left margin Neofundulus was restricted to the original descriptions of the Paraguay river.

  • Thesis Submitted in Fulfilment of the Requirements for the Degree of Masters of Science by Research
    Factors influencing hybridisation and introduction success of the critically endangered Running River rainbowfish, Melanotaenia sp. Karl Moy B. Zool. (Hons) Institute for Applied Ecology University of Canberra A thesis submitted in fulfilment of the requirements for the degree of Masters of Science by Research 7th of August 2019 i Abstract Given that conservation introductions are essentially biological invasions, researching the main factors which influence them will provide insight for both conservation and management. The factors affecting invasion success in small-bodied Australian freshwater fishes are largely unstudied. From a conservation-oriented perspective this is worrying as small-bodied freshwater species are more likely to become threatened than large-bodied species. It is equally concerning from an invasive species management perspective as many species have the potential to negatively impact native species and ecosystems. This thesis consists of two data chapters preceded by a general introduction and followed by a synthesis. The first data chapter examines potential pre and post zygotic barriers to hybridisation between the Running River rainbowfish (RRR) and eastern rainbowfish (Melanotaenia splendida). Eastern rainbowfish is a widespread native fish of northern Australia with an alien population in Running River (a tributary of the Burdekin River, Queensland). Hybridisation between RRR and eastern rainbowfish has been detected and in the absence of barriers to further hybridisation and introgression will likely lead to the loss of pure RRR from the wild. Dichotomous mate choice experiments and egg survival experiments were used to determine the presences of pre and post-zygotic barriers to hybridisation between RRR and eastern rainbowfish. The findings of this study do not support the presence of barriers to hybridisation between the two species.
