This book is a unique cross fertilization of aquatic ecology and
aquaculture. It shows how diets structure the digestive tract and
its microbiota and, in turn, the microbiota influences life history
traits of its host, including behavior. Short-term starvation can
have beneficial effects on individuals themselves and succeeding
generations which may acquire multiple stress resistances - a
mechanism strengthening the persistence of populations. From
terrestrial, but not yet from aquatic animals, it is understood
that circadian the rhythmicity makes toxins or good food. On the
long-term, the dietary basis impacts succeeding generations and can
trigger a sympatric speciation by (epi)-genetics. This volume
defines gaps in nutritional research and practice of farmed fishes
and invertebrates by referring to knowledge from marine and
freshwater biology. It also points out that dietary benefits and
deficiencies have effects on several succeeding generations,
indicating that well designed diets may have the potential to
successfully improve broodstock and breeding effort.
The future of the Common Fisheries Policy depends on progress in
the relevant areas of research. This applies to the whole range of
management decisions, where precise, reliable and complete data are
essential to inform those who must decide on the pursuit of
existing activities, especially in the area of maritime fisheries
and the development of promising new activities such as
aquaculture. The Commission wishes to act as a catalyst by
promoting the circulation of information and the co-ordination of
research programmes. DG XIV has therefore decided to compile this
directory, which lists the research centres of the Member States.
Specific information from each research centre is also listed, for
example research activities and facilities.
This book introduces the theory and practice of Chinese freshwater
fish culture to the world. Fish resources, reproduction, feeding
and nutrition, genetics and breeding, fry and fingerling nursing,
integrated fish farming, fish culture in lakes, reservoirs, pens
and cages, luxury species culture, as well as disease control are
described. A representative collection of the Chinese literature is
cited, most of it exposed to the world for the first time. This
volume will be invaluable to all aquaculturists and
animal/fisheries scientists.
This book provides a comprehensive and up-to-date review of the
ecology of coral reef fishes presented by top researchers from
North America and Australia. Immense strides have been made over
the past twenty years in our understanding of ecological systems in
general and of reef fish ecology in particular. Many of the
methodologies that reef fish ecologists use in their studies will
be useful to a wider audience of ecologists for the design of their
ecological studies. Significant among the impacts of the research
on reef fish ecology are the development of nonequilibrium models
of community organization, more emphasis on the role of recruitment
variability in structuring local assemblages, the development and
testing of evolutionary models of social organization and
reproductive biology, and new insights into predator-prey and
plant-herbivore interactions.
This book is about important relevant recent research topics in
sustainable aquaculture practices. A critical assessment of the
sustainable fishing methods and the aspect of sustainable
aquaculture feed is presented in this volume. A special focus has
been given to socio-economic and environmental assessment of
aquaculture practices and analysis of carbon footprint under an
intensive aquaculture regime. Aquaponics as a niche for sustainable
modern aquaculture has been highlighted. The effect of use of
pharmaceuticals to prevent fish disease on the surrounding marine
environment is an emerging area of concern, and a critical
discussion on this aspect is included in the book. The spread of
organic waste and nutrients released by fish farms to natural water
bodies has raised considerable concerns. Therefore the methods to
prevent their dispersion and removal (treatment) have been
comprehensively covered in this book. This book is an essential
read for academician, researchers, and policy makers in the field
of aquaculture.
This book compiles the latest findings in the field of marine and
brackishwater aquaculture. It covers significant topics such as
techniques of culture of live feeds (microalgae, rotifer, Artemia,
marine copepod & polychaetes), while also highlighting vital
themes like the culture and applications of free and marine sponge
associated microbial probiotics, controlled breeding, seed
production and culture of commercially important fin and shell
fishes. Moreover, the book focuses on the breeding and culture of
marine ornamental fishes, sea cucumber and sea urchin and discusses
seaweeds culture, aqua feed formulation and nutrition, water
quality management in hatchery and grow-out culture systems, fish
disease diagnosis and health management and cryopreservation of
fish gametes for sustainable aquaculture practices, all from a
multidimensional perspective. The global fish production was 154
million tonnes in 2011 which more or less consisted of capture and
culture fisheries (FAO, 2012). Roughly 80% of this is from
inland-freshwater aquaculture and the remainder from capture
fisheries in the marine and brackishwater sector. However, marine
and brackishwater catches have recently begun to diminish due to
overexploitation, climate change and pollution. The UNEP report
affirmed that if the world remains on its current course of
overfishing, by 2050, the ocean fish stock could become extinct or
no longer commercially viable to exploit. In these circumstances,
aquaculture is considered to be a promising sector to fulfill our
future protein requirement. However, brackishwater and marine fish
production now face serious challenges due to e.g. lack of quality
fish seeds, feeds, poor water quality management and diseases.
Fisheries and aquaculture sectors play a vital role as potential
sources of nutritional security and food safety around the globe.
Fish food is rich in protein, vitamins, phosphorous, calcium, zinc,
selenium etc. In addition, fish contains omega-3 fatty acids, which
help to prevent cardiovascular diseases. Fish food can also provide
several health benefits to consumers. The omega 3 fatty acids found
in fish can reduce the levels of LDL cholesterol (the "bad"
cholesterol) and increase the HDL levels (the "good" cholesterol).
Research conducted in Australia has proved that fish consumption
can be used to cure hypertension and obesity. It is also reported
that people who ate more fish were less prone to asthma and were
able to breathe more easily. Omega 3 fish oil or fish consumption
can help to prevent three of the most common forms of cancer:
breast cancer, colon and prostate cancer. The omega 3 fatty acids
present in fish or fish oil induce faster hair growth and prevent
hair loss. Since most varieties of fish are rich in protein, eating
fish helps to keep hair healthy. Furthermore, fish or fish oil
helps in improving the condition of dry skin, giving it a healthy
glow. It is useful in treating various skin problems such as
eczema, psoriasis, itching, redness of skin, skin lesions and
rashes. It is well known that eating fish improves vision and
prevents Alzheimer's and type-2 diabetes, and can combat arthritis.
Further, fish oil or fish is good for pregnant women, as the DHA
present in it helps in the development of the baby's eyes and
brain. It helps to avoid premature births, low birth weights and
miscarriages. In addition, it is widely known that fish can be a
good substitute for pulses in cereal-based diets for the poor. The
global fish production was roughly 154 million tonnes in 2011 (FAO,
2012). It is estimated that by 2020 global fish requirements will
be over 200 million tonnes; as such, innovative technological
improvements are called for in order to improve the production and
productivity in fisheries. In this context, this book provides
valuable information for academics, scientists, researchers,
government officials and farmers on innovative technological
advances for sustainable fish production using aquaculture methods.
The book identifies the main issues and trends in marine and
brackishwater aquaculture from a global perspective in general and
in the Indian context in particular. It includes 23 chapters
written by prominent researchers from various institutes and
universities across India, who address the latest aquaculture
technologies with distinctive approaches to support academics,
researchers and graduates in the fields of Fisheries, Aquaculture,
Marine Science, Marine Biology, Marine Biotechnology, Zoology and
Agricultural Sciences. Our thanks go to our contributors; we are
confident that all readers will immensely benefit from their valued
expertise in the field of marine and brackishwater aquaculture.
This is a reprint of the first revision of this classic. Originally
published in 1953 as Fishery Bulletin #74 for the US Department of
the Interior, Fish and Wildlife Service. The "Gulf of Maine" is
defined as an area from the Nantucket Shoals and Cape Cod in the
west to Cape Sable in the east. The aim of the book was to provide
a handbook for the easy identification of the fishes that occur in
the Gulf of Maine, with summaries of what is known about the
distribution and relative abundance together with information on
the life history of each species. The authors used the 150-fathom
boundary as the arbitrary offshore boundary as this will exclude
almost all "deep-sea" fishes, which are numerous in the basin of
the open Atlantic. Combining information gleaned from the
literature as well as surveys from a large number of cruises, the
volume covers the Cyclostomes, cartilaginous fishes, torpedoes,
skates and rays and the bony fishes. The descriptions are as
non-technical as is compatible with scientific accuracy and are
limited to external features that will aid in identification in the
field.
"Oryzias latipes," known as medaka, is a model organism from
East Asia. Breeding of this small, egg-laying freshwater teleost
fish has long been popular among hobbyists in Japan. Now, as
biological science has entered the genome era, the medaka provides
significant advantages that make it one of the most valuable
vertebrate models: a large collection of spontaneous mutants
collected over a century, the presence of highly polymorphic inbred
lines established over decades, and a recently completed genome
sequence. This book is the first comprehensive monograph to cover a
variety of medaka research. It opens with a historical view of
medaka, followed by a series of research topics in the four major
areas where the medaka is increasingly important: genomics,
genetics, and resources; organogenesis and disease models; germ
cells, sex determination, and reproduction; and evolution. Readers
will find state-of-the-art information on medaka genetics and
genomics such as the first isolation of active transposons in
vertebrates, the influence of chromatin structure on sequence
variation, fine QTL analysis, and versatile mutants as human
disease models.
Fish farming has increased in status equal to cattle farming as a
source of food for mankind. In developing countries fish and
shellfish provide inexpensive animal protein, while in developed
countries aquaculture is expected to produce more fish and
shellfish as a source of low-calorie protein for health conscious
individuals. In such an era, knowledge of fish farming technologies
of different countries, strongly influenced by cultural factors, is
of valuable importance. The primary production techniques of fish
farming in Japan described here have an emphasis on practical
technology. This second edition reflects the changes in both
quantity of production and technology in Japanese aquaculture. The
statistics have been revised and the text rewritten to suit the
current status of aquaculture in Japan; new aquaculture species
have been included and discussions on marine ranching and
biotechnology for aquaculture added.
This second volume in the series covers such topics as DNA
fingerprinting of fishes, the cytochromes P450 in fish, the
molecular biology of bacterial fish diseases, and new insights into
the origins of the diversity and distribution of fish antifreeze
proteins. The book will be of great value to fisheries scientists,
animal biochemists, physiologists and endocrinologists, and
aquaculturists. It will provide researchers and students alike with
a pertinent information source from theoretical and experimental
angles.
This international symposium allowed many researchers and
industrial representatives to meet and discuss a broad spectrum of
information such as zero emission, resources availability,
sustainable utilization of resources, bioactive and functional
components in aquatic organisms, utilization of wastes, seafood
quality, surimi technologies and processing and safety. The book
aims: To provide a current record presented in the international
symposium More Efficient Utilization of Fish and Fisheries
Products, 7-10 October 2001, Kyoto, Japan; To provide a stimulus to
researchers in this area to cross-fertilize ideas and demonstrate
examples of success; To enhance values and returns to fisheries
fields in national and international terms by providing
descriptions of better techniques and methods for utilizing the
catch, reducing waste, and providing valuable by-products.
