As an estuary, the river level fluctuates with the tides. This flow brings in nutrients from the sea, which makes the Iloilo River a nursery for fish species such as bangus and tilapia. The banks of the river are home to 22 of the country's 35 mangrove species, as well as the rare metapenaeus insolitus.[1]
Iloilo River wharf, including Muelle Loney Street in the Iloilo City Proper, is a natural harbor which made it a preferred port of call for ships seeking protection from strong winds and tropical monsoons. It serves as port for inter island ferries that travel from Iloilo City to Bacolod on Negros and to Guimaras. It is also a drop-off point for fishing vessels that bring in their catch from the sea to be delivered to markets all over Iloilo.
Port
The Port of Iloilo was opened for international trade on 1855 and the coming of British Vice-consul Nicholas Loney, a year later, that led to the fast development of sugar industry in the region.
Esplanade
The Iloilo River Esplanade is a park development stretches on both sides of the river banks constructed as a recreation area and an attraction for visitors.[2]
