Age determination in fish. Removing an otolith from a red snapper to determine its age. Knowledge of fish age characteristics is necessary for stock assessments, and to develop management or conservation plans. Size is generally associated with age; however, there are variations in size at any particular age for most fish species making it ...
In 1927-1928 Michael Graham conducted the first ever systematic Fisheries Survey of Lake Victoria. The dominant species in the 1927–8 survey catches were two, now critically endangered tilapia species, the 'Ngege' or Singida tilapia ( Oreochromis esculentus) and Victoria tilapia ( O. variabilis ).
