Jim Shortreed, #VictoriaBC based #herring #enhancement #volunteer , is not fully convinced of the precautionary principle. He said #DFO electronic surveys indicate the returning #biomass is low; however, he claims DFO continues to say the sonars are not calibrated & therefore contain a certain amount of #error in every reading. The only way to know how much #HerringReturns to #spawn is after the spawn when #eggs are #counted
