Philippines country information

Common names: [No common name]
Occurrence: endemic
Salinity: freshwater
Abundance: fairly common (chances are about 50%) | Ref: Anonymous, 1993
Importance: minor commercial | Ref: Bleher, H., 1996
Aquaculture: | Ref:
Regulations: restricted | Ref:
Uses: no uses
Comments: Endemic to Lake Bombon (=Taal), Batangas (Ref. 280).It is believed to be the only freshwater sardine in the Philippines which immigrated from Balayan Bay to Taal Lake (Ref. 81621). Reported harvest in 1984 was over 29,000 tonnes, by 1995 it was below 60 t (Ref. 12165). In 1998, production was at a high of 1120 mt, but down to 294 mt in 2000 (Ref. 80723). Threatened due to overfishing (Ref. 12165, 13446). Also Ref. 188, 12550, 58652,13446.

Asia: endemic to Lake Taal (formerly Lake Bombon), Luzon, Philippines. This freshwater lake, linked to the sea via the Pansipit River, was part of Balayan Bay, South China Sea, and was formed by a series of volcanic eruptions in the 18th century (Ref. 5522).

Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 15-18; Anal spines: 0; Anal soft rays: 18 - 21; Vertebrae: 39 - 42. Total scutes 28 to 30. gill rakers slender, long and numerous (Ref. 5520).

Biology     Glossary (e.g. epibenthic)

Inhabits lakes. This is the only species of Sardinella that is apparently found only, or even mainly, in freshwater. Presumably schooling. Also caught using ring nets (Ref. 5520). Mainly caught by gill net, beach seine, ring net and motorized push net (Refs.81494, 80728, 5520). Eaten fresh or dried (Ref. 5517). Is threatened by overfishing (Ref. 6308).

IUCN Red List Status (Ref. 90363)

Threat to humans

  Harmless
