BERITABETA.COM – Apart from being a species that is beautiful and able to change color, shape and even sex, Parrot fish can play an important role in providing the sand needed to build and maintain coral reefs.
A published study revealed the huge role of old Parrotfish in their habitat on healthy coral reef ecosystems.
The Research was carried out in the Maldives and published in the journal Geology and found that Parrotfish produced more than 85% of new sand sediment on the coral reefs surrounding the islands.
Coral islands are a unique landscape consisting entirely of sediment generated on the surrounding coral reefs. Although it is important for island development and future maintenance, the most important sources of sediment for constructing islands and the rate at which these sediments are produced are poorly understood.
Professor Chris Perry from the Department of Geography at the University of Exeter, lead author of the study state that previous research had highlighted how important Parrotfish are to the general health of coral reefs in particular.
The main reason are they help to control algae growth and promote coral recruitment
“Our study quantifies another interesting aspect of these species, namely their primary role in producing the sediments that are needed to build and maintain coral islands,” he said.
Based on survey and sediment data, the researchers investigate the relationship between coral reef ecology and sediment production around the island of Vakkaru, Maldives.
According to Reports by the University of Exeter on April 28, 2015, researchers identified parrot fish as a large sand producer, producing more than 85% of new sand sediment produced on the outside of the reef each year.
The Parrotfish grind the corals when they eat.
After they digest their edible contents, they excrete the leftover food in the form of sand, which can then be transported to the coastlines of adjacent islands.
Professor Perry added that coral reef islands are considered to be one of the most vulnerable landscapes to climate change and especially to future sea level rise.
This study demonstrates the important relationship that exists between the ecology of the reefs surrounding these islands and the sand supply processes.
“We provide evidence that protecting Parrotfish populations and the habitats on which they depend, will likely be important to ensure the supply of sediment to the coral islands in the Maldives,” he explained.
The results of this research, of course, are very difficult to be realized by the wider community. This is because parrot fish is a species of marine fish that is quite popular with the community.
This fish has a lot of nutritional content for health, which is well known, of course, as a low-fat protein source. In addition, this fish also contains a lot of omega 3 and omega 6 which are good for brain growth.
Apart from meat, the waste of Parrotfish scales is also very useful to make gelatin which is used as raw material for capsules for health and beauty medicine.
According to lecturer FPIK Unsrat Prof. Ineke Rumengan accompanied by Prof. Wilhemina Patty and Albert Reo, these findings were obtained from a series of studies that also involved students.
Based on these findings, the FPIK Unsrat research student team consisting of Jeszy Andakke, Hizkia Nainggolan, Lasma Parapat managed to qualify for the competition at the National level in PIMNAS in Bali since last August 2019. (BB-DIO)
