This book was released on 1982 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The variation in the environmental factors encountered, the habitat occupied and preferred, patterns of activity, aspects of growth, reproduction and food consumption by the central mudminnow, Umbra limi were studied to illustrate the mudminnow's adaptations to the spatial and temporal pattern of its environment. Mudminnows inhabit and show a preference for areas with cover which is consistent with their morphological, behavioural and physiological adapations. Mudminnows showed variations in time of activity. Crepuscular, nocturnal and diurnal activities were observed at different times and places. Enhanced survival of females is one of the life history strategies exhibited by mudminnows. Females (age 2+) were usually larger and more abundant than males. Age at first maturity was two for females and one for males. Time of spawning varied between years in the streams studied and some females did not spawn at all in 1979 ... Feeding occurred in the vegetated areas of streams. Benthic, mid-water, surface and organisms attached to vegetation were included in the diet. Mudminnows were euryphagic carnivores and ate aquatic and terrestrial invertebrates and fish (which became more important as the temperature dropped) ... The central mudminnow responds to a heterogeneous environment by specializing in habitat and generalizing in time of activity, life history and feeding strategies.

Download or read book Freshwater Fishes of Manitoba written by Kenneth Stewart and published by Univ. of Manitoba Press. This book was released on 2004-05-03 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manitoba's ninety-three species of fish give the province the third most diverse fish population in Canada. The provinceís variety of geological features, with its major lakes, rivers, tributaries, and watersheds, is due in large part to its history as the basin for Glacial Lake Agassiz. This, combined with its access to the waters of Hudson Bay and large American river systems, has provided habitat for a wide diversity of freshwater fish. Species from lampreys to goldeye, catfish to perch, bigmouth bass to slimy sculpin swim in waters from arctic rivers in the north to Red River tributaries and down to the Mississippi in the south.Freshwater Fishes of Manitoba is a comprehensive, user-friendly guide. Each species is accurately depicted in detailed colour photographs and accompanying map, with descriptions of physical characteristics, spawning and feeding habits, distribution, habitat, ecological role, and economic importance. The guide also includes an extensive glossary, keys to identifying the families, species, and subspecies, and information on documentation and preservation of specimens. Freshwater Fishes of Manitoba is not only the definitive guide to these fishes of Manitoba, it is also accessible and reliable for a range of users from general fishers to professional fish biologists.

Download or read book Migration of Freshwater Fishes written by Martyn Lucas and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have increasingly demonstrated the widespread existence of spatio-temporal variations in the abundance and distribution of species of freshwater fishes, previously assumed not to move between habitats. These movements are often on a seasonal or ontogenetic basis, for spawning, feeding and refuge, and in many cases are fundamental for the successful completion of lifecycles. This important book provides a single source for a range of previously widely dispersed information on these movements of fish in fresh waters, covering potamodromous fishes as well as the more familiar diadromous species, worldwide. Contents include full descriptions of types of migration and spatial behaviour, the stimulus and capacity for fish to migrate, the effects of climate on patterns of migratory behaviour, a taxonomic analysis (mostly by family) of freshwater fish migration, methods for studying migration, and details of the impacts of man's activities on freshwater fish migration. Migration of Freshwater Fishes provides an excellent and comprehensive reference to which the river manager, biologist or student can now refer to obtain information, advice and current opinion on the migratory behaviour of most taxonomic groups of fishes occurring in fresh water. University libraries and aquatic research stations should also have copies of this essential reference book on their shelves. Well-known international authors. Of great commercial importance to fisheries and professional angling bodies. Draws together much new information in one place. Detailed review of world wide migratory behaviour for most groups of freshwater fishes. Pure and applied relevance, for academics, fisheries scientists, river managers and conservationists. This comprehensive book includes 67 tables and figures and over 1,400 references.

This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish are extremely successful vertebrates. Because of a long and divergent history they are now found in almost every conceiv able aquatic habitat. This radiation has been accompanied by great diversity in structure, physiology, and behaviour. Despite this variability, fish must solve a number of basic problems that are common to all animals. The most important of these are: (1) to find and ingest appropriate food; (2) to avoid predation; and (3) to reproduce. The main purpose of this book is to describe the variety of behavioural strategies that fish use in coping with these problems. My approach has been to draw together material from both field and laboratory work that is widely scattered in the litera ture. The major emphasis is on field studies, since my main concern is with adaptive solutions to problems, and I believe these are most likely to be correctly perceived by workers who are familiar with the natural ecological setting of their animals. Of course, many details of behaviour cannot be seen and quantified adequately in the field, and therefore I have not ignored laboratory studies. However, even here I have concen trated on work that illustrates the variety of solutions that fish use to solve the three basic problems. Much important work, for instance on causation, development, and learning, is not included.
