studies on improved practices of prawn farming for higher ...

v.
Careful analysis of data accrued by the author has helped
him to identify strength, weakness, opportunities and threats
confronting the shrimp farming.
As a result it was possible to evolve an appropriate
management technology taking into consideration the various ecological
(location specific), social and economical conditions prevalent in the
vast study area.
Shrimp farming being a seasonal activity and_the fields
having located in different areas, the author had to struggle hard
spending considerable time and energy to complete the investigation
over an extended period, from 1986 to 1992. Alongwith it, case,
pilot and experimental <strong>studies</strong> were carried out to identify
potentially useful tools, if any, for resource management.
On many occasions, author could not exercise complete control
over the investigations owing to the varied nature of culture
systems. Yet added attention was paid to draw as much information
as possible in such situations.
Prawns- versus sh reimg
At a time when the terms prawns and shrimps are used
vaguely it is felt necessary to clarify the usage of the word
"Shrimps" in the thesis. This is an important question as the usage
of these terms is becoming a matter of concern to distinguish each
other. According to the recommendations of the Indo—Pacific
Fisheries council in 1955, the term "prawn" should be used only in
respect of the members of the family Penaeidae, Palaemonidae and
Pandalidae and the term "shrimp" to species of other families.
However, as early as 1967, FAO introduced a clear cut distinction
that the term "prawn" will be reserved for fresh water creatures
only, while their marine/brackish water relatives will all be called
"Shrimps". This was further emphasised in the conference organised
