Download or read book Identification guide to the mesopelagic fishes of the western Indian Ocean written by Mostarda, E., Harold, A.S., Sutton, T.T., Hulley, P.A. and published by Food & Agriculture Org.. This book was released on 2023-10-17 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive guide encompasses a total of 473 species of mesopelagic fishes (i.e. those fishes residing primarily between 200 and 1 000 m depth during daytime) that are known to occur in the western Indian Ocean. It aids in their accurate identification, offering dichotomous keys to all taxa. Species are treated in detail, with accounts including the scientific name, FAO common name in English (where available), other useful characters, size, a distribution map, and one or more illustrations. Captions and arrows enhance user-friendliness for to both specialists and non-specialists in the field of ichthyology. In the broader context of marine ecology, mesopelagic fishes hold a pivotal role as integral components of the marine food web, serving both as predators and prey for various species. This guide not only enriches our understanding of these fishes but also contributes to our knowledge of the western Indian Ocean's diverse ecosystem. Beyond species identification, it sheds light on the interconnectedness of marine life and underscores the importance of conservation efforts in safeguarding this delicate balance. This guide serves as an invaluable resource for in-depth exploration and research into these remarkable fishes, offering a comprehensive tool for studying their diverse characteristics, behaviours, and ecological significance, essential elements for sustainable management and conservation practices.

Download or read book Hermaphroditism and Mating Systems in Fish written by Tetsuo Kuwamura and published by Springer Nature. This book was released on 2022-12-13 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive review of hermaphroditism in fishes. It focuses on the behavioral ecology of functional hermaphroditism in fishes and discusses its evolution. Approximately 99% of all vertebrate species consist of separate-sex individuals (gonochorists), i.e., pure males and pure females. The other 1% of vertebrate species are hermaphroditic, and almost all of them are fishes. Among hermaphroditic fishes, four major types of hermaphroditism are known: simultaneous (or synchronous) hermaphroditism, protandry (male-to-female sex change), protogyny (female-to-male sex change), and bidirectional sex change (or reversed sex change in protogynous species). The book examines the occurrence of hermaphroditism in relation to phylogeny and mating systems. It also reviews the hypotheses for the evolution of hermaphroditism, and the size-advantage model, which is the main theory for the evolution of sex change, tested in relation to the mating system. The appendix in the last chapter provides an annotated list of hermaphroditic fish species (ca. 500 spp.).

Download or read book Monograph of the Gonostomatidae and Kahliellidae Ciliophora Hypotricha written by Helmut Berger and published by Springer Science & Business Media. This book was released on 2011-01-06 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present monograph is the fourth of six volumes which review the Hypotricha, a major group of the spirotrichs. The book is about the Gonostomatidae, the Kahliellidae, and some taxa of unknown position in the hypotrichs. Gonostomum was previously misclassified in the Oxytrichidae because its type species Gonostomum affine has basically an 18-cirri pattern, which is dominant in the oxytrichids. A new hypothesis, considering also molecular data, postulates that this 18-cirri pattern evolved in the last common ancestor of the hypotrichs and therefore it appears throughout the Hypotricha tree. The simple dorsal kinety pattern, composed of only three bipolar dorsal kineties, and gene sequence analyses strongly suggest that Gonostomum branches off rather early in the phylogenetic tree. Thus, the Gonostomatidae, previously synonymised with the oxytrichids, are reactivated to include the name-bearing type genus and other genera (e.g., Paragonostomum, Wallackia, Cladotricha) which have the characteristic gonostomatid oral apparatus. The Kahliellidae are a rather vague group mainly defined via the preservation of parts of the parental infraciliature. The kahliellids preliminary comprise, besides the name-bearing type genus Kahliella, genera such as Parakahliella and its African pendant Afrokahliella or the monotypic Engelmanniella. In total 68 species distributed in 21 genera and subgenera are revised. As in the previous volumes almost all morphological, morphogenetic, molecular, faunistic, and ecological data, scattered in almost 700 papers, are compiled so that the four volumes (Oxytrichidae, Urostyloidea, Amphisiellidae and Trachelostylidae, Gonostomatidae and Kahliellida) provide a detailed insight into the biology of almost 500 species of hypotrichs. The series is an up-to-date overview about this highly interesting taxon of spirotrichous ciliates mainly addressed to taxonomists, cell biologists, ecologists, molecular biologists, and practitioners.

Download or read book A Review of the World Resources of Mesopelagic Fish written by J. Gjøsaeter and published by Food & Agriculture Org.. This book was released on 1980 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fish species can be called mesopelagic if it spends the day in the mesopelagic zone. The mesopelagic zone has been defined in different ways based on depth, temperature and light regimes. For the present purpose, depth seems to be the best criterion and mesopelagic fish can thus be defined as species generally spending the day at depths between approximately 200 and 1 000 m. Generally they perform a diel migration, coming to the upper 200 m or even to the surface during the night. The present report briefly reviews the systematics ecology and life history of important groups of mesopelagic fish. Further, some methods used for abundance estimation of these fish are described and discussed. The bulk of the report reviews the present knowledge of abundance and species composition of mesopelagic fish in each of the FAO statistical areas. Although the data in most cases are few, an attempt has been made to give tentative estimates of the biomass and production in the various areas. When available, information on the life history of the most important species in each area is also given.
