Fish (or ornamental fish) is the common name for these fish are kept for ornamental or decorative in a space, any landscape. The common feature is the type of fish for ornamental beauty is always superior than other types of fish just to eat normally.Aquarium hobby has from time immemorial, such as goldfish (Carassius auratus) has been adopted in court under the Song Dynasty - China and then spread among the people.
The aims of this paper were to investigate the component fatty acids of some freshwater fish
species by comparing the levels of essential fatty acids present. The FAME were determined
by GC-MS and were identified using retention time locked methods and retention time
databases. The fatty acids profiles include minor amounts of odd-number, branched-chain,
and even-number fatty acids as well as saturated components, the MUFA and PUFA. The
major SFA were C14:0 and C16:0. The C18:1 was the prominent MUFA....

Small-scale freshwater fish farming
This Agrodok aims at providing basic information on how to set up a small-scale fish farm for subsistence purposes. As fish farming practices are very diverse, we have chosen to limit ourselves
The main objectives of this study were to examine the effects of coastal eutrophication on fi sh communities,
and on local recreational fi shery and commercial pikeperch fi shery on the northern coast
of the Gulf of Finland. The study focused on freshwater species, as they live their entire life cycle in
the most eutrophied areas, i.e., the archipelago and inner bays. Freshwater species are important for
the very popular recreational fi shery, forming the bulk of the annual total catch.
Myanmar was hit by Cyclone Nargis in May 2008 with winds
of 190km/hour and an enormous sea surge. It destroyed
houses and even whole villages and caused massive
fl ooding with an offi cially estimated death toll of 140,000
people and the livelihoods of 2.4 million people seriously
affected. I outlined issues relating to small-scale aquaculture
in articles in previous columns (‘Myanmar revisited’ in the
January-March 2009 issue and ‘Small-scale aquaculture
in the Ayeyarwady Delta’ in the April-June 2009 issue).
Part II: Planning a fish farm

Land, water and climatic conditions are probably the most important natural factors that need to be assessed. When developing a site for fish farming you should consider the effect it may have on the environment. Important natural areas
There is increasing awareness of the nature and
complexity of the processes influencing river
channels and the maintenance of fish habitats.
Increased understanding highlights the sensitivity of
these processes and the way in which they also
underpin the biodiversity and amenity value of
rivers. It shows the need for careful planning and
design if management is to be sustainable and is to
achieve its objectives without producing
unanticipated and detrimental impacts. There is a
clear need to consider carefully the consequences of
management intervention in river channels.
3.1 Fish farming ponds
Different pond types
Depending on the site, there are two different types of fish ponds to choose from: diversion or barrage ponds.Diversion ponds Diversion ponds (figure 3) are constructed by bringing water from another source to the pond.
7 Selecting the fish species
When selecting fish species suitable for farming, various important biological and economic factors need to be considered: 1 market price and demand (not when fish are produced for own consumption) 2 growth rate 3 ability to reproduce in captivity 4 simple culture of the young fish 5 match
9.1 Harvesting and post-harvesting
Harvesting the fish
As in any other type of farming, the final phase in the fish farming cycle is the harvest and possible sale of the fish. When most of the fish are big enough to be eaten or sold, harvesting can start (usually after 5 to 6 months).
Product Description Freshwater aquarium hobbyists will find all the information they need regarding purchasing, feeding, and maintaining this delicately-hued tropical fish. Heavily illustrated with vivid color photos and instructive line art, Barron's Complete Pet Owner's Manuals show and inform pet owners regarding proper care of dogs, cats, birds, fish, reptiles, amphibians, small caged animals-
Aeromonas hydrophila and other motile aeromonads are among the most common bacteria in
freshwater habitats throughout the world, and these bacteria frequently cause disease among
cultured and feral fishes. From descriptions of fish diseases in the early scientific literature, Otte speculated that septicemic infections in fish caused by motile aeromonads were common
throughout Europe during the Middle Ages. Although the bacterial etiology of these early reports
was inconclusive, the pathology was similar to that observed with red leg disease in frogs, in
Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.
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.

Thailand is blessed with an abundance of marine and freshwater resources. In 2002 it
ranked in the top-ten fishing nations of the world. Thailand is also recognised for the
advances it has made in developing its aquaculture sector.
Capture fisheries and aquaculture in the Thai portion of the Lower Mekong Basin are a
major component of these aquatic resources. It has been estimated from fish
consumption studies that the average annual yield of inland fish is around 795,000
small water bodies like ponds now contributes 80% of the country’s inland
fish production. However, future growth in freshwater aquaculture to meet
rising demand for fish is likely to be constrained by limited supplies of land for
digging new ponds and of water to fill them.
In this context, reservoirs offer immense scope for increasing fish production.
