Gonadosomatic Index (GSI) data was gathered as part of work looking into
breeding season of Ballan wrasse. Fish samples were obtained from March 2018
to May 2019. Samples were obtained via local fishers using pots, traps and rod
and line and subsequently processed back at the lab. Both fish weight (WT to
nearest g) and gonad weight (WG, to 0.1g) were obtained in order to
ascertain the GSI. The data set comprises of female fish from the Weymouth bay
area from March 2018 to May 2019. The minimum GSI observed was 0.039GSI and
Maximum observed 8.904GSI. The data shows the GSI in relation to the time of
year the fish were captured.
