Inappropriate Species for Mercy Release

The intention of releasing trapped animals – returning the right of survival to them, is appreciated. However, such action requires thorough consideration and calculation beforehand in order to avoid any possibility of disrupting the eco-system, which might eventually violate the philosophy and kind intention behind. Some species are inappropriate for releasing.


1. Exotic Species

Animal releasing has been a controversy for years as alien species which are not easily recognized by the public have often been introduced and used for releasing, and hence disturb the local eco-system. Exotic species may compete with the native species for resources or even prey on them. Among all releasing species, Sabah Grouper – hybrid of Giant Grouper and Brown-marbled Grouper, tops the list of popularity and controversy because of its relatively low price and remarkable growth rate. Sabah Groupers compete intensively with the native species for food (small fish) as well as rapidly bring down the population of small fish due to its monstrous appetite. Sabah Groupers are, undeniably, disastrous to the local eco-system.


2. Animals on the market

It is quite convenient to purchase animals for releasing from vendors who offer options for their customers. Yet, most of the animals are weak because of long travel and packed captivity. Those animals may, very likely not survive the wild after being liberated. This would apparently defy the kind intention of animal release.

3. Birds

It is not recommended to release birds no matter they are native species or not. Most of the birds are captured and confined which probably lead to illness. They are relatively vulnerable, and might even get sick due to overwhelming stress. The odds of the bird dying of weakness is considerably high. In addition, 75% of released bird died according to SPCA’s research. Moreover, bird release may jeopardize public health in case the animals are infected by viruses such as avian flu.


4. Insects

Release of insect should be strictly avoided as most of them are alien specie which might die immediately or, on the other hand, jeopardize the survival of native plants and crops. Because of their small sizes a huge amount of insect is often released, and they usually linger around due to their limited mobility. Surge of biomass is resulted which leads to disruption of the equilibrium of the eco-system rapidly.
