Fry (first mobile offspring) of the Midas cichlid,Cichlasoma citrinellum, feed on the epidermal mucus of their parents. Ingesting mucus increased at first then fluctuated during the four-week period of parental care of swimming young (fry). Total protein in the mucus was assessed using Bio-Rad-Protein-assays. Western blots revealed prolactin (tiPRL 177 and traces of tiPRL 188) and growth hormone (tiGH). Thyroxine (T4) was also detected quantitatively by RIA. Fry with parents grew faster… CONTINUE READING
