Book excerpt: The aim of this thesis was to examine the enzymatic degradation of algal carbohydrates by marine herbivorous fishes to determine which dietary carbohydrates are digested directly by the fishes, which are available for microbial fermentation, and which remain undigested. Enzyme extracts were taken serially along the gut from the gut wall, gut fluid and microbial pellet of Girella tricuspidata, Girella cyanea, Kyphosus sydneyanus, Aplodactylus arctidens, Aplodactylus etheridgii, Parma alboscapularis and Odax pullus and tested for activity against starch, laminarin, carrageenan, agarose, alginate, fucoidan and carboxymethylcellulose. In all species, hydrolysis of starch was greater than for all other substrates tested and was highest in the gut wall and anterior gut sections, indicative of endogenous origin. Activity in the anterior gut wall varied between species in the order G. tricuspidata (23607 units min−1) > G. cyanea (15664 units min−1) > A. etheridgii (6464 units min−1) ) > P. alboscapularis (5303 units min−1) > A. arctidens (3327 units min−1) > K. sydneyanus 1295 units min−1) > O. pullus (501 units min−1 ). In all cases hydrolysis of starch declined rapidly in the gut fluid with progression along the gut. Amylolytic enzymes in K. sydneyanus and A arctidens are the result of a-amylases, which display peptide sequence homology to a-amylases from other vertebrates including marine fishes. Activation energies indicate that a-amylases from K. sydneyanus and A. arctidens are more efficient at low temperatures, consistent with the distribution of these species. Enzyme activity against all other carbohydrates was lower than that against starch and varied considerably between species. Microbial extract of A. etheridgii displayed the highest activity against carrageenan and agarose in all gut sections, reaching maxima of 47 units ml−1 against carrageenan and 35 units ml−1 against agarose in the mid-gut microbial extract. This is much higher than for the other non-starch carbohydrates tested, indicating that these enzymes are potentially important substrates for microbial fermentation in A etheridgii. Carrageenases from A. etheridgii and A arctidens were examined more closely and found to have some peptide sequence homology to sulfatases from marine bacteria as well as novel sequence. Carrageenases studied have properties consistent with their environment including low temperature optima, indicative of cold-adaptation. Overall results of this research indicates that the study species fall along a continuum from maximizing throughput and digesting easily hydrolysed substrates in the foregut to relying more heavily on microbial fermentation in the hindgut.

Book excerpt: Fish form an extremely diverse group of vertebrates. At a conservative estimate at least 40% of the world's vertebrates are fish. On the one hand they are united by their adaptations to an aquatic environment and on the other they show a variety of adaptations to differing environmental conditions - often to extremes of temperature, salinity, oxygen level and water chemistry. They exhibit an array of behavioural and reproductive systems. Interesting in their own right, this suite of adaptive physiologies provides many model systems for both comparative vertebrate and human physiologists. This four volume encyclopedia covers the diversity of fish physiology in over 300 articles and provides entry level information for students and summary overviews for researchers alike. Broadly organised into four themes, articles cover Functional, Thematic, and Phylogenetic Physiology, and Fish Genomics. Functional articles address the traditional aspects of fish physiology that are common to all areas of vertebrate physiology including: Reproduction, Respiration, Neural (Sensory, Central, Effector), Endocrinology, Renal, Cardiovascular, Acid-base Balance, Osmoregulation, Ionoregulation, Digestion, Metabolism, Locomotion, and so on. Thematic Physiology articles are carefully selected and fewer in number. They provide a level of integration that goes beyond the coverage in the Functional Physiology topics and include discussions of Toxicology, Air-breathing, Migrations, Temperature, Endothermy, etc. Phylogenetic Physiology articles bring together information that bridges the physiology of certain groupings of fishes where the knowledge base has a sufficient depth and breadth and include articles on Ancient Fishes, Tunas, Sharks, etc. Genomics articles describe the underlying genetic component of fish physiology and high light their suitability and use as model organisms for the study of disease, stress and physiological adaptations and reactions to external conditions. Winner of a 2011 PROSE Award Honorable Mention for Multivolume Science Reference from the Association of American Publishers The definitive encyclopedia for the field of fish physiology Three volumes which comprehensively cover the entire field in over 300 entries written by experts Detailed coverage of basic functional physiology of fishes, physiological themes in fish biology and comparative physiology amongst taxonomic Groups Describes the genomic bases of fish physiology and biology and the use of fish as model organisms in human physiological research Includes a glossary of terms

Available in PDF, EPUB and Kindle. Book excerpt: "This thesis examined the nutritional ecology of a single species of marine herbivorous fish, the New Zealand butterfish Odax pullus (Labridae). Its aim was to establish whether this species could provide any evidence for a temperature constraint on digestion in an ectothermic herbivore foraging at high latitudes. Specimens of wild O. pullus were sampled across three locations within New Zealand, which covered a latitudinal range of 11° and encompassed a year-round temperature range of 10-22oC. Diet was determined through examination of ingested material and also through analysis of stable isotopes (15N and 13C) in diet and consumer tissues. The nutrient content of material in the foregut of captured fish was quantified on the basis of ash, total hydrolysable amino acids (THAA), total lipid, and hydrolysable neutral sugars (including the sugar-alcohol mannitol). Assimilation efficiencies were calculated and, subsequently, digestion was also considered in terms of the pattern of changing nutrient concentrations along the gut. Finally, digestive activity in the hindgut was characterised using a metabolite profiling approach. An ontogenetic change in the diet of juvenile O. pullus was observed at all locations. During early development, fish switched from an omnivorous diet of epiphytic rhodophyte algae and epiphytic invertebrates to an herbivorous diet dominated by phaeophyte algae. Diet switching coincided with a decrease in ingested protein and lipid concentrations and a corresponding increase in the ingested concentration of crude carbohydrate. However, even on an herbivorous diet, juveniles ingested a higher protein to carbohydrate ratio than adult fish. Differences in the size at which the ontogenetic diet switch occurred were observed across locations. Since these differences also coincided with variation in the availability of dietary algae, they could not be interpreted as evidence for a temperature constraint on the development of herbivory in this species. Seasonal effects on the diet and nutrition of adult fish were examined at a single location (36°S), and significant variation in diet across the year was found for both sexes. Variation in ingested nutrient content was significant for female fish; where a high protein to mannitol intake was related to changes in nutritional demand associated with spawning activity. Nutrient assimilation efficiencies did not vary significantly across seasons, except for mannitol, which was utilised with greater efficiency during the colder half of the year. Across locations, diet analysis revealed that adult O. pullus were exclusively herbivorous during the months that sampling took place (December - February), and stable isotope analysis supported the conclusion that fish at all locations were herbivorous year-round. Ingested concentrations of protein were consistent across locations. Furthermore, mannitol was consistently present in the diet at greater concentrations than any other sugar measured and was utilised with near 100% efficiency. Comparisons of digestive activity and nutrient assimilation along the gut indicated similar levels of hindgut microbial activity at all locations. On the basis of these results it was concluded that hindgut fermentation of mannitol made a significant contribution to the nutrition of O.pullus throughout the majority of its natural species range. This study therefore provides no evidence to suggest that the digestion of algal material by a marine ectothermic herbivore is constrained by decreasing temperatures associated with latitude".

Book excerpt: Fish Nutrition aims to present the state of knowledge of basic and applied nutritional requirements of fishes. Most of the information found in this book involves salmonids, their nutrition, and metabolism of nutrients. This is in view of the fact that more research has been done and completed with this fish. Although applied fish nutrition is a very broad field, this book focuses on some of its aspects. These include the classes of nutrients and requirements for several types of fishes. This book comprises of 11 chapters. The first few chapters deal with the general nutrient requirements of fishes. Then, other chapters discuss calorie and energy as well as micro- and macronutrient needs and requirements. The following chapters deal with the non-nutrient components of the diet, or those that influence the characteristics of food products including texture, odor, flavor, and color. Other topics covered are enzymes and systems of intermediary metabolism (Chapter 6); feed formulation and evaluation (Chapter 7); and salmonid husbandry techniques (Chapter 9). Nutritional fish diseases are also discussed in this book. Some of these diseases include thyroid tumor, gill disease, anemia, lipoid liver degeneration, and visceral granuloma. In Chapter 11, the relationship of nutrition and pathology is given emphasis. This chapter also tackles the diet and general fish husbandry. This topic is very important, because an adequate diet for fish husbandry is the foundation of fish farming.
