For a population of animals to grow and thrive, the first
requirement will always be adult specimens of both genders that have reached
reproductive age. The more whales mating in a region, the bigger the area pods
can grow. With the 17 month long gestation period necessary to produce a baby
orca, population growth can be understandably slow without a high level of
breeding activity. Female orcas are especially essential, as one of these is
required for each and every infant birth. A male is involved, too, of course,
but a single energetic and virile male can impregnate an entire pod of females.
The marine mammal entertainment industry was aware of this fact when they began
harvesting orca whales in the late 1960s.
In 1965, the first captive orca was placed on display, and
the general public soon lost their fear of "killer" whales, as they discovered
the gentleness and intelligence of these majestic creatures. At this point, the
tables turned, and the animals that had once reigned solely as predators
suddenly became prey. Marine parks, such as SeaWorld, organized/supported
violent round-ups in the Pacific Northwest to stock their facilities with a
popular new showpiece - the killer whale. These captures targeted young,
trainable orcas, with an emphasis on females that could be used in park
breeding programs.
Orca captures affecting the Southern Resident populations
were conducted in the Salish Sea from 1966 - 1973. During this brief period, 45
orcas were taken from the Southern Resident pods to live in captivity. This
number is more than half of the current total population of J, K, and L-pods.
In addition, 13 more orcas lost their lives amidst the violence surrounding the
captures.
Stolen family members made for a drastic population
reduction in the wild whale pods of the late 20th century, but the
after-effects of this travesty have continued on through today. Because so many
young females were abducted from the Southern Resident orca pods, fewer remain
to reproduce. For example, Lolita, the last captive survivor of the infamous
1970 Penn Cove round-up, is one of many lost Southern Residents who could, if
swimming free with her pod, be actively breeding and restoring the local
population. A healthy female orca will give birth to a calf approximately once
every 5 years.
Is there any way to repair the damage inflicted upon the
Southern Residents by past captures? As wild whale round-ups are no longer
legal, it has become a case of 'what's done is done'. There is no way to bring
back the many orca whales that have died in captivity, but a glimmer of hope
remains in the idea that Lolita could be successfully reunited with her L-pod
family where she would potentially mate and reproduce. Click
