Percid Fishes: Systematics, Ecology and Exploitation by John F. Craig

By John F. Craig

The percid fishes (or perch relations) contain many species together with the perch, pikeperch, yellow perch, walleye and the darters. those species are of serious ecological and monetary value, being vital elements of the freshwater atmosphere and leisure and advertisement fisheries.

Percid Fishes covers points resembling systematics, morphology, biology, ecology, ailments and parasites and the industrial significance of percid fisheries. exact emphasis is positioned in the e-book at the advanced dating among this relatives of fishes and their surroundings and the way they reply to perturbations, in particular these precipitated by way of humans.

the writer, John Craig who has loads of event engaged on those fishes in lots of of the nations during which they ensue, has drawn jointly a very vital ebook which supplies a distinct, accomplished and crucial assessment of this most vital crew of fish.Content:
Chapter 1 Taxonomy and Distribution (pages 1–14):
Chapter 2 Morphology and Anatomy (pages 15–38):
Chapter three Age, development and Mortality (pages 39–54):
Chapter four copy and improvement (pages 55–77):
Chapter five nutrients and Feeding (pages 78–107):
Chapter 6 Ionic and Water stability (pages 108–115):
Chapter 7 Swimming, pursuits and Migrations (pages 116–123):
Chapter eight Parasites and ailments (pages 124–146):
Chapter nine inhabitants Dynamics and group constitution (pages 147–167):
Chapter 10 Fisheries and monetary significance (pages 168–190):
Chapter eleven Aquaculture (pages 191–224): Patrick Kestemont and Charles Melard
Chapter 12 Etheostomatinae (pages 225–253): Lawrence M. Page
Chapter thirteen different Percinae and Luciopercinae (pages 254–261):

The discovery of new marine habitats and communities and the growing threats to marine species from environmental change and disturbances, make it increasingly important to develop rapid and robust ways of describing and cataloguing marine biodiversity. Hebert et al. (2003) introduced the concept of a DNA barcode, and proposed a new approach to species identification which could overcome many of the limitations mentioned above. The method is based on the premise that the sequence analysis of a short fragment (658 nucleotide base-pairs) of a single gene (cytochrome c oxidase subunit 1, commonly called COI), enables unequivocal identification of almost all animal species.
