Result of the studies made on   live sharksucker (commonly known as sucker
fish) Linnaeus 1758
collected from November 2003 to October 2005 from the Central west coast of India is
discussed in this study.  Study indicated
the dominance of male with a sex ratio (M:F) of 1:0.4.  Length–weight relationship for male and
female sucker fish was W=0.0006536 L 3. 3829 (r=0.98) and W=0.0002620 L 3. 6255 (r=0.93)  respectively.   Regression equations between them differed
significantly (F= 35.83). There were seven stages of maturity and twelve stages
of ova observed in the species.  Ova
observed were between 5-8 and 169-172 micrometer division (0.1 - 0.16 mm and
1.85-1.89 mm respectively).  Size at
first maturity was 51cm.  Fish appears to
be a batch   spawner.   About 38% of the fishes were found with
empty stomachs.  Gut content analysis
showed that the food items are mainly cephalopods and juvenile fishes
especially lizard fishes, goat fishes, threadfin breams and anchovies.  Females were found to be poor feeders.
