ONE PLATE
In this paper is given the description of a new macrurus crustacean, Paltmon luzonensis sp. nov. This commercial shrimp,
known in Iloko as aramang, is taken in large quantities at the
mouth of Cagayan River from August to January. A small
drag seine (bannuar) is used in catching the aramang with the
aid of a small boat (balasiang).
The shrimps are usually dried in the sun along the beach, but
during the rainy season they are generally salted and fermented
into bagoong. The value of dried and salted products from the
aramang fishery of Cagayan is estimated at 10,000 to 15,000 pesos 1 annually. Dried aramang is packed in boxes or sacks and
shipped to Manila and the Ilocos provinces, mostly by Chinese
but also by a few Filipino dealers. From September to December, 1937, about 720 cavanes, or 54,000 liters 2 of aramang,
valued at 4,320 pesos, were shipped to Manila and the Ilocos
provinces. So far there is no record of the value of dried aramang and bagoong made of aramang sold in the interior towns of
Cagayan Valley.
