when did vancouver aquarium get rid of orcas
Vancouver Aquarium For many years, the primary attraction for visitors was the orca show. The Aquarium was the first to capture and display a killer whale, Moby Doll, in a pen at Burrard Drydocks, for 3 months in 1964. Since then, it was home to Skana, Hyak II, Finna, Bjossa, and three of Bjossa's calves. When Finna died and Bjossa was left without other orca companions, the Aquarium attempted to acquire one or more female orcas from other marine parks. However, no suitable companions were found, and Bjossa was moved to SeaWorld, San Diego, in April 2001 where she later died due to a chronic respiratory illness. The Aquarium has since moved to emphasize the educational aspects of the displays rather than the public spectacle of the shows. They have also highlighted their research, rescue and rehabilitation efforts.
Yellow tang Often ranked as a good beginner fish in the marine aquarium industry, the more prudent approach is for them to be kept by a marine aquarist who has at least two years' experience of successfully keeping a marine/reef type biotope. They require an aquarium of 55-gallon show tank size (48"L × 21"H × 13"W) at the absolute minimum, whereas a single smaller specimen 2"–3" may be kept[clarification needed] provided it is done by an experienced marine aquarist who can provide the fish with highly stable water chemistry parameters, very low to undetectable nitrate levels and a highly nutritious, balanced diet of seaweed and high protein frozen or live, meaty foods. A 75-gallon tank or larger is better for a single specimen, while an aquarium of 100 gallons or 60" or more in length is ideal.
