This volume, the first in a series, presents the findings of an ambitious
project—to measure the impact of fishing on the ecosystems
that make up the North Atlantic Ocean and to propose ways to mitigate
that impact. The project arose from a request by Dr. Joshua
Reichert, the Director of the Environment Program of the Pew
Charitable Trusts, Philadelphia, to answer six specific questions
about the North Atlantic:
• What are the total fisheries catches from the ecosystems, including
reported and unreported landings and discards at sea?...
In many parts of the world the primary source of animal protein for humans is finfish. The
intensive culture of finfish has grown significantly since the 1980s partly because of the
dramatic decline in the natural fish stocks and the increase in fish consumption by the
ever-increasing population. For example, the worldwide consumption of fish between
1990 and 1997 increased by 30% while the capture fisheries increased only by 9%.
The world ocean has somewhere between 10 000 and 100 000 seamounts more than 1 km
tall and as many as 1 000 000 features over 100 m tall. These are some of the least understood
habitats on the planet. Large seamounts, particularly those close to or within the
photic zone, support and attract rich biotic communities and are important for the status
of marine food webs and biodiversity. Intensive boom-and-bust fi sheries have depleted
fi sh populations and damaged or destroyed associated benthic communities.
The beneficial aspects of stress diminish when it is severe enough to over-
whelm a child’s ability to cope effectively. Intensive and prolonged stress
can lead to a variety of short- and long-term negative health effects.
It can disrupt early brain development and compromise functioning of the
nervous and immune systems. In addition, childhood stress can lead
to health problems later in life including alcoholism, depression, eating
disorders, heart disease, cancer, and other chronic diseases.
Bacillary necrosis occurs very often in intensive
farming of Tra catfish (Pangasius hypophthalmus)
in the Mekong delta. Causative bacterium was
identified as Edwardsiella ictaluri. Diseased fish
with typical focal necrosis in the liver, kidney and
spleen were sampled from 17 fish farms in Can
Tho, Dong Thap, Vinh Long, An Giang and Ben
Tre Province for bacterial isolation and
identification. Among 97 isolates, 47 (48 %) were
identified as E. ictaluri.
Tiger shrimp (P. monodon) and marine fishes are common fish cultured in coastal area of Vietnam. The study on nutrition for such species has not much when compared to freshwater fish species. Trash fish is the traditional feed for marine cultured fish and tiger shrimp in semi-intensive system. The supply is not stable in term of quality and quantity. Moreover, the price has increased. Therefore, finding alternative feed for trash fish is very important and crucial issues Using pellet feed in which fishmeal was replaced by plant protein that started in 90’s decade.
The mask is a surprising and wonderful relation of center and circumference, of
containment and freely going forth, giving it a vibrant sense of life. Its intense, terrified and also
sad expression seems to withdraw inward into the purity and whiteness of self while feathers,
hands, fins, seal flippers, spindles, circles radiate, almost explode from its enclosed central form
Jutting out from around the top of the head are white feathers and extending behind them is an
arched reed that forms a wider oval.
We now live in a world where more intense weather, patterns of droughts and floods are
becoming commonplace, as are overexploited fish stocks, destroyed forests and dried up rivers.
The era of post-war consumerism, where humanity lived in a world rich in resources that were
thought boundless, is closing as ecological limits become apparent around the world.
We have to face the fact that our consumption of everyday products has a global impact....
The Baltic Sea is a unique basin, being productive with intensive fishing potential
and has therefore been the object of many studies. It is a brackish, nontidal,
relatively shallow and semi-enclosed sea. The Baltic is located at a high latitude,
hence one of its characteristic features is ice. Another unique geographical
pattern are the archipelagos located off the coast of Stockholm which consist of
more than 25 000 islands. The relative ionic concentration of toxic substances e.g.
chemical elements is generally higher in the low-saline Baltic Sea than compared
to the North Sea....
Ecologically, Ennore Creek is the most strategic
place where many industries started mushrooming in and
around the creek in the late 1970s led to meristamatic
growth affecting the fishing community (Arunagiri et al.,
1998). The environmental degradation of the Ennore
Creek is structurally different from the problem of
pollution of the metropolitan city of Chennai. This narrow
creek is one among the most polluted creeks along the
Eastern Coast, which is not only receiving worldwide
attention, but also one of the areas demanding intensive
La Ribah Agro India Pvt Ltd is originated from one of the most fascinating industries called agricultural industry.La Ribah Agro India is the result of the group of the most bustling personnel by their intense knowledge and exposure into the agricultural field. La Ribah Agro India has assorted projects in the areas of farming as in Emu Farming, Goat Farming, Horse Farming, Rabbit Farming, Dairy Farming, Fishing and Fish Farming. Farming is also the most beneficial, ravishing and product oriented form of business.
The importance of fish in vertebrate evolution has been better recognized
in recent years after the intense work carried out on fish genomics. The
recent discovery that fish genomes comprise homologs of ribonucleases,
studied before only in tetrapods, and the isolation of ribonucleases from
zebrafish have suggested an experimental model for studying fish and verte-brate evolution.
