The intense mobility of the fish during reproduction causes disturbance and hence water renewal, according to the latest findings of researchers.
According to the Daily Mail, researchers from University of SouthamptonThey discovered that the waters in the coastal areas mix during the spawning of anchovies, anchovies and smaller fish in general, which helps in the circulation of nutrients and oxygen.
According to the researchers, the process of fish reproduction is the key to maintaining the functioning of ocean ecosystems and preserving life.
The mixing of the oceans is vital to enable the transfer of heat, oxygen, nutrients and pollutants between different layers.
While previous studies have shown how winds and tides contribute to mixing, to a lesser extent so far little has been known about the contribution of animals.
In their study, the team observed water turbulence on the Ria de Pontevedra, a bay off the northwest coast of the Iberian Peninsula, for 15 days.
Using an instrument called microstructure profilerthe researchers were able to observe tiny fluctuations in ripple and temperature.
Their analysis showed that despite the fact that for these 15 days apnea prevailed in the area, the turbulence in the water increased every night as fish were gathered in the bay to reproduce.
