according to a previous paragraph the taxes on the daclis de 
ipon in the town of Caoayan alone, not including the sarep 
localities, amounted to at least 1,360 pesos. 
A conservative estimate of the value of the ipon fisheries of 
Abra River based on the average of the catches of individual 
fishermen, on the estimates of various officials and traders, and 
on the taxes for the nets and traps for catching ipon, amounts 
to well over 350,000 pesos annually. Various estimates made 
by the municipal treasurers and secretaries were invariably 
between 400,000 and 500,000 pesos. These last estimates are 
too large, save during exceptional years, as the size of the catch 
varies from year to year. 
To use this fish for canning would be feasible. Without doubt 
such a canned product would find a ready sale in interior towns. 
Possibly it might take the form of a paste such as the anchovy 
paste now found in European and American markets, or the 
ipon might be preserved in a piquant sauce and used as a relish 
with curry or preserved in oil and used the same as salmon and 
other fish products. 
Appended is a statement obtained from the Provincial Treas- 
urer of Ilocos Sur of tax receipts for towns along Abra River.
