Gonadosomatic Index of individual Ballan Wrasse caught from Weymouth Bay 2018 to 2019

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.
