Global Times, 7/23/12, By Shen Shushu
Recently, hundreds
of dead fish were found in the Huangpu River near the Bund. The initial
reaction was that the fish must have fallen victim to water pollution, but this
turned out not to be the case. The fish had been deliberately released into the
river, and because this species, the crucian carp, is not native to the river and
are not accustomed to such high temperatures, they quickly perished.
This is not the
first case of people "freeing" animals from capture, only for this
action to ironically hasten their demise. The act derives from certain
religious beliefs in which it is thought that good "karma" or luck
will accrue to a person who releases animals back into their natural habitat.
Since 2005, hundreds of animals of many species - catfish, snails, turtles, and
even crocodiles and piranhas - have been dumped in lakes and ponds in parks in
many downtown areas including the City God Temple and Xujiahui.
The problem is that
these "do-gooders" are actually upsetting the ecological balance of
nature by releasing species into environments in which they will do more harm
than good. For example, naturally aggressive species of fish such as catfish
and blackfish (species of angelfish) need to be bred separately in ponds; in
rivers they will quickly overrun, and even wipe out native species.
Unfortunately angelfish are often chosen to be released by these misguided
good-fortune hunters because in certain belief systems these fish are said to
have "holy genes."
Overseas species
such as the red-eared turtle, nicknamed the Brazilian turtle, will also wreak
devastating consequences if they are mixed with local species in rivers,
causing untold damage to the biological diversity of our waterways.
And if you imagine
we are talking about people picking up a few fish at the local wet market,
putting them in a bag, and then slinging them into the nearest river or canal -
then think again. There are cases on record of people ordering 40,000 yuan
($6,264) worth of fish and then driving the load to the Huangpu River and
pouring the lot in. The fish are kept in water-filled tank at all times, so that
they don't die during the journey. It was reported that these lorry loads were
actually followed by fishermen so that they could set about re-catching the
fish as soon as possible!
If people insist on
carrying out this traditional ritual, I would suggest that they learn more
about the species they intend dealing with and making sure that they release
them back into the same kind of environment in which they were bred.
