Abstract:
Morphometric
relationships of length–length (carapace and total body length) and
length–weight (wet body weight) were analyzed during nursery, grow out,
and broodstock production phases of Farfantepenaeus paulensis ranging
in size from 0.06 to 60 g (n=2969). Morphometric data during the
broodstock production phase were pooled for males and females, as no
significant differences in regression lines between sexes were observed.
Shrimp from the broodstock production phase tended to have longer and
heavier bodies compared with grow out individuals with the same carapace
length. Increments on body weight (BW) were proportional to total length
(TL) rather than carapace length for nursery, grow out, and broodstock.
Conversion equations relating the measures of length and weight are provided
for each culture phase. The use of a general morphometric relationship
between total length and body weight (BW=0.07×10−3 (TL)3.058)
is recommended to simplify the management in different culture phases of F.
paulensis in southern Brazil.
