The visual feeding threshold and action spectrum of northern anchovy (Engraulis mordax) larvae
(California Cooperative Oceanic Fisheries Investigations, 1983)
The visual feeding threshold and action spectrum of 10-15-mm northern anchovy larvae were determined, using as criterion the incidence of two or more rotifers in the guts of 50% of larvae tested under different spectral ...

Sulphide tolerance and adaptation in the California killifish, Fundulus parvipinnis, a salt marsh resident
(Wiley-Blackwell, 1993)
Hydrogen sulphide is a toxicant naturally produced in hypoxic marine sediments, hydrocarbon and brine seeps and hydrothermal vents. The California killifish, a salt marsh resident, is remarkably tolerant of sulphide. The ...

From triphenyltins to integrated management of the 'pest' snail Cerithidea cingulata in mangrove-derived milkfish ponds in the Philippines
(Kluwer Academic Publishers, 2000)
The potamidid snail Cerithidea cingulata is considered a pest in brackishwater milkfish ponds in the Philippines and has been controlled by the triphenyltin (TPT) compounds Aquatin and Brestan. But TPT is also toxic to ...
The sulfide tolerance of milkfish and tilapia in relation to fish kills in farms and natural waters in the Philippines
(Kluwer Academic Publisher, 1998)
Fish kills of milkfish Chanos chanos and tilapia Oreochromis spp. now occur frequently in brackish, marine, and freshwater farms (ponds, pens, and cages) in the Philippines. Aquafarms with high organic load, limited water ...
