This book was released on 2018-03-15 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Ecology of the Gulf of Mexico Commercial Spongers and Its Relation to the Fishery The results of 2 years of study on the ecology of the commercial sponges and the relationship of sponge ecology to the commercial sponge fishery are discussed. A review and fiber analysis of the various commercial sponge species are pre sented. Reproduction of sponges is reviewed, and the effects of temperature and population concentration on reproduction are discussed. Data on the growth rate of wool sponges are presented, and a growth formula calculated. Temperature, salinity, depth of water, water currents, dispersion, population concentration, disease, commensalism, rock bar communities, and other environmental relation ships are discussed. The sponge fishery from 1936 to 1958 is reviewed along with an analysis of take per unit of effort, sponging methods, and relationship of fishing and take to the sponge ecology. Present status of the industry is reviewed, and recommendations made that might assist in increasing the harvest of sponges. Projected increases in sponge population and sponging areas are analyzed.

Book excerpt: Excerpt from Ecology of the Gulf of Mexico Commercial Spongers and Its Relation to the Fishery Although the first record of sponge taking in Florida dates from 1822, it was not until 27 years later (1849) that domestic sponges became a commercially valuable product in the United States. By the time diving gear was in use for sponging in 1905, concern was already being expressed about conversation of this valuable resource. This concern resulted in 4 years of extensive research (Moore, 1910a, 1910b) on sponge cultivation methods. His reports also included descriptions of sponging methods, the sponge grounds, and the commercial species of sponges. No other major investigation of the Florida sponges was undertaken until the outbreak of the sponge disease in 1938. The results of this investigation was reported by Galtsoff (1942) and Smith(1941). In 1947 and 1948, the State of Florida Board of Conversation authorized the University of Miami Marine Laboratory to make limited surveys of the Florida sponge grounds between Key West and Carrabelle. This resulted in the published accounts of the economic history of the industry (Smith, 1949; Storr, 1956), a report of the expeditions (Dawson and Smith, 1953), and a description of the commercial and noncommercial sponges collected (de Laubenfels, 1953). Meanwhile, by 1951, production had fallen to less than 3 percent of the 1936 peak and the dollar returns 1946 value when more than $3 million worth of sponges were sold.

Download or read book The Cell Biology of Sponges written by T.L. Simpson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modem biology owes much to the study of favorable model systems which fa cilitates the realization of critical experiments and results in the introduction of new concepts. Examples of such systems are numerous and studies of them are regularly recognized by the scientific community. The 1983 Nobel Prize in Med icine and Physiology is a magnificent example in which com plants served as the experimental model. In a manner somewhat more modest, other biological systems have attracted recognition due to their critical phylogenetic position, or indeed because of their uniqueness which distinguishes them from all other organisms. Assuredly, among the whole assemblage ofliving organisms, sponges stand out as worthy of interest by scientists: they are simultaneously models, an important group in evolution, and animals unlike others. As early as the beginning of this century, sponges appeared as exceptional models for the study of phenomena of cell recognition. Innumerable works have been dedicated to understanding the mechanisms which assure the reaggregation of dissociated cells and the reconstitution of a functional individual. Today, re search on these phenomena is at the ultimate, molecular level. Through an as semblage of characteristics the sponges are, based upon all available evidence, the most primitive Metazoans. Their tissues-perhaps one can say their cell groups-are loosely assembled (they possess no tight or gap junctions), cell dif ferentiation appears highly labile, and they do not develop any true organs. But, they are most certainly Metazoans.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains full papers of both oral and poster presentations of the international symposium 'Marine Bioprocess Engineering' which was held in Noordwijkerhout, The Netherlands, 1998. The symposium focused on the bioprocessing of marine natural products.Bioprocess engineering has been the key to success in the commercialization of biotechnology, especially with respect to biopharmaceuticals. In marine biotechnology, both new and existing biotechnological techniques are developed an applied to organisms from marine sources. For marine biotechnology, bioprocess engineering represents the link between discovery and commercialization.The diversity of marine life points to a myriad of new bioproducts waiting to be discovered and developed commercially.The volume begins to bridge the gap between the isolation of products from marine organisms in the laboratory and industrial applications by focusing on the bioprocess-engineering aspects. Reviews and recent developments in product discovery, bio-energy production, cultivation of marine organisms, scale up and product recovery are presented.This publication should ensure that the engineering aspects of marine biotechnology will receive further attention in the future. Exploration of new bioproducts from the ocean should be followed up by a sustainable exploitation of these valuable resources.
Download or read book Invertebrates written by Sajal Ray and published by BoD – Books on Demand. This book was released on 2020-01-22 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invertebrates exhibit a wide range of diversity in body plan, physiology, behaviour, adaptation and preferences for habitat and food. Their relationship with the environment is unique and multidimensional. This book is organized into two sections containing chapters on the frontier areas of research in ecophysiology and management-related problems of various invertebrates. Topics covered include hibernation physiology; the amelioration potential of drug and parasitic host response of molluscs; the genetics and biology of hydrocorals; and current trends of management, aquaculture, and harvesting of ecologically and economically important molluscs and sponges. This book is an enriched edition of invertebrate zoology and is a useful source of information for researchers and students in various disciplines. In recent years, a paradigm shift in research on invertebrates has occurred under the backdrop of climate change and environmental contamination. This important shift in the research is well reflected in this book.

Download or read book Marine Biological Materials of Invertebrate Origin written by Hermann Ehrlich and published by Springer Nature. This book was released on 2019-10-17 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work is a source of modern knowledge on biomineralization, biomimetics and bioinspired materials science with respect to marine invertebrates. The author gives the most coherent analysis of the nature, origin and evolution of biocomposites and biopolymers isolated from and observed in the broad diversity of marine invertebrate organisms and within their unusual structural formations. The basic format is that of a major review article, with liberal use of references to original literature. There is a wealth of new and newly synthesized information, including dozens of previously unpublished images of unique marine creatures and structures from nano- to microscale including high-resolution scanning and transmission electron micrographs. The material is organized effectively along both biological (phyla) and functional lines. The classification of biological materials of marine origin is proposed and discussed. Much of the pertinent data is organized into tables, and extensive use is made of electron micrographs and line drawings. Several modern topics e.g. “biomineralization- demineralization-remineralization phenomena”, or “phenomenon of multiphase biomineralization”, are discussed in details. Traditionally, such current concepts as hierarchical organization of biocomposites and skeletal structures, structural bioscaffolds, biosculpturing, biomimetism and bioinspiration as tools for the design of innovative materials are critically analyzed from both biological and materials science point of view using numerous unique examples of marine origin. This monograph reviews the most relevant advances in the marine biomaterials research field, pointing out several approaches being introduced and explored by distinct laboratories.
