Abstract: ã€€ã€€As early as half a century ago. Hudinaga successfully spawned and attempted to
rear the larvae of Penaeus japonicus. Publications in the 1960's,70's and 80's on
breakthroughts in larvel rearing of one penaeid species after another indicated
that practical prawn farming had become a reality. At present, there are 24 Peneaus
species and seven Metapenaeus species whose larval rearing techniques are partially
or fully established. Among them, only nine species are propagateed on a large
commercial scale. The other species are now produced only on a small scale or
  There are many published papers dealing with larval rearing techniques of
penaeid prawns. However, it is recognized that numerous details and problems remain
unsolved pending further investigation and improvemant. P.japonicus is the species
which boasts the longest reserch history and the most successful larval rearing
techniques. Nevertheless, there is little which scientists are able to do with the
serious "white-turbid midgut gland disease" which has plagued the postlarvae of
P.japonicus for the past several years. Similarly, P.monodon larval culture in
the Philippines was once seriously affected by a fungus disease cause by Lagenidium
sp., which resulted in poor survival rate.
  Suitable larval rearing methods differ from one species to another, all showing
varying degrees of modification from the major principles of larval rearing techniques
of penaeid prawns. For example, a hatchery can easily obtain several hundred spawners
of P.japonicus, but this is never the case with P.monodon. Therefore, the community
culture method for rearing larvae in large tanks is preferred for the former speies,
while the separate tank method, also called the monoculture method,is best for the latter.
  In general, larval rearing techniques of prawns is at its rapid growing stage. The status of
larval rearing including rearing method, feeding regimes and rearing systems, are herein
summarized and introduced. The high priority problems to be solved such as 1) selection of
spawners, 2)improvement of rearing techniques, 3)larval diseases, 4) shipping methods, and
5) social impact are discussed and the prospects of larval rearing are described.
