In some parts of Mekong Delta, Vietnam, immature fish are excessively
caught. What issues does this cause and how can they be addressed?
Overfishing of young fish in Vietnam's Mekong Delta
It is true that overfishing of juvenile fish is a concern in several areas of
Vietnam's Mekong Delta. Although this trend may result in several problems related
to the ecosystem, the government can take steps to mitigate these potential problems.
As many fishermen use destructive fishing methods and overfishing, several
related problems can be anticipated. The principal issue is that there will
undoubtedly be a decline in the number of fish species, which will reduce
biodiversity and disrupt the food chain. Particularly, numerous little fish and huge
fish are killed when some fishermen use electricity or explosives to catch fish, which
severely impedes the replenishment of the seafood supply. As an illustration,
gigantic tuna is a natural adversary of jellyfish, but overfishing is causing them to
go extinct, which is one of the main causes of jellyfish outbreaks in many areas. The
jellyfish ate a lot of little fish eggs and larvae, which had an adverse influence on
rate of the fishery recovery and had a domino effect on all the organisms in the
vicinity. Additionally, the over-exploitation of commercially significant fish species
poses a threat to the depletion of the seafood resource and has a direct impact on the
livelihood of fishermen. In other words, if there aren't any more fish or other seafood
to capture, fishermen and other people employed in the fishing business will lose
their employment, adding to the burden on society. Take the statistics of the first
quarter of 2022 of the General Statistics Office as an example, the labor force
decreased by nearly two thousand people compared to the same period last year.
However, there are several actions that government could take to tackle the
above-mentioned problems. Propaganda and education are the first steps that should
be taken. Nowadays, most locals are still unaware of the seriousness of destructive
exploitation, so lectures and presentations on the issue are required at agricultural
conferences and educational institutions. The second solution is that the government
inspects fishing boats before they set sail and severely punishes cases of willful
violations to discourage and stop such situations. The third option would be to
establish more marine protected areas by the government in order to allow fish
populations and their ecosystems to recover and replenish themselves and secure
fishing for future generations.
Finally, as long as illegal fishing methods are prevented, it will create favorable
conditions for fishery resources to recover, and those engaged in the fishing business
won't be out of job.
In conclusion, a variety of measures can be taken to tackle the issues that are
certain to arise as humans over-exploit marine resources.
In truth, some imperative measures ought to be taken to resolve these
prospective issues.
