[1] Pasaleng Bay is located 16 kilometres (9.9 mi) east of the centre of Pagudpud, Ilocos Norte.

[7] The Cordillera Mountains, located in the central part of the island of Luzon, also terminate at the bay.

[8] The bay is reported to have type II climate with distinct dry and wet seasons, akin to the Cagayan Valley.

[1] From 2000 to 2006 under the National Stock Assessment Project (NSAP), 319 fish species were caught including marine organisms.

[10] Above the Pasaleng Bay, near the Mairaira Promontory between Kagayan and Hokos Norte at the foot of the Calvario Mountain there are two stone images one of an old man and the other of a woman.

The practice followed by sailors crossing in front of these statues is to offer a basket coconut shell filled with food and tobacco as they believe that it has spiritual powers and protects them while passing through the turbulent waters of the bay.

[11] A six-year study of the fishing industry in Pasaleng Bay has been carried out during the period from 2000 to 2005 under the National Stock Assessment Project (NSAP) in the 16 coastal barangays of the municipality.

The monitoring studies have indicated that there are 319 species of marine organisms of 59 families, 169 fishing boat (50% are fitted with engines) operate 457 fishing gears of 16 types and the three dominant catches in the descending order of their catch are skipjack tuna, bigeye scad and frigate tuna.
