Aim: The Lemon fin barb
hybrid was developed by crossing Lampam (Barbonymus gonionotus)
females with Kerai (Hypsibarbus wetmorei) males as a potential food source
for lower income people in Malaysia due to fast growth and ease of
culture. For delicious flesh and high market demand, the farming of
this hybrid has subsequently expanded rapidly. Many of the basic
biological aspects of this hybrid have not yet been investigated and in this
study the embryonic and early larval development were examined.
Methodology: After injecting
the brood-stocks with hormones, the matured eggs and sperms were collected by
strip spawning. The developing embryonic stages were subsequently observed at
10 min intervals for the first hour, 20 min intervals at the second hour, 30
min for the next hour, and then hourly intervals up to hatching. After
hatching, observations continued at 2 hr intervals for the first day and a
minimum of 6 hr intervals for the following days.
Results: In the
consortium, there was more than 2-fold increase in the maximum algal specific
growth rate and a 1.3-fold increase in the maximum bacterial specific growth rate.
Furthermore, the maximum ethylene glycol removal efficiency by consortium was
89%, while those by bacteria monoculture was 31%. No apparent removal
of ethylene glycol by the C. fusca monoculture was observed.
Interpretation: This study represents
the first description of the early development stages for Lemon fin barb
hybrids that may assist with the establishment of seed production and rearing
techniques for aquaculture development in Malaysia.
