That was nice to have some fishing activities in San Diego region. The information obtained will be developed into useful posts. The photo was taken in a Tuna Harbor fish market. Thanks to everyone who welcomed my questions and provided enough information. Andrea (who is in grade 4 and Ken in grade 8) are not only selling fish but they go in fishing trips with their father. In the second photo, Mr. Kawika who is a fisherman and I joined in the fishery. Technical information will follow on series activities which are namely whale watching, marine fish farm, sea world and open fish market. Thanks. Abdel Rahman El Gamal
