BIO MAR IV — Fishing · IMO 7525188

BIO MAR IV has not broadcast an AIS position for 10 days. The most recent broadcast placed it in the South Pacific Ocean, on 28 Oct 2026, 17:33 UTC. It was sailing from SAN VICENTE to SAN VICENTE. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

BIO MAR IV broadcasts MMSI 725000460 and is registered as IMO 7525188. The MMSI is the radio identifier used by AIS; the IMO number stays with the ship for life and does not change with re-flagging or sale.

BIO MAR IV is classified as a fishing vessel registered under the CL flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full fishing fleet at /vessel-type/fishing and full CL flag list at /flag/cl.

AIS transponders broadcast position every 2 seconds when underway at high speed and up to every 3 minutes at anchor. The position you see refreshes whenever the ship is in range of a coastal AIS receiver or a satellite pass — typically seconds in coastal waters and minutes offshore.

As a fishing, BIO MAR IV sits in the same design class as the other fishings listed in the Similar Vessels section of the vessel page, or in the full fishing directory at /vessel-type/fishing.
