The relatively short life cycles of harpacticoid copepods makes them appropriate animals for use in tests that rapidly assess the #180, sublethal, or chronic effects of sediment contaminants. In this study, four harpacticoid copepod species (Nitocra spinipes, Tisbe tenuimana, Robertgurneya hopkinsi, and Halectinosoma sp.) were isolated from clean marine sediments, and procedures for laboratory culturing were developed. Halectinosoma sp. was abandoned due to handling difficulties. For the remaining species, the influence of food type and quantity on life-cycle progression was assessed. A mixed diet, comprising two species of algae (Tetraselmis sp. and Isochrysis sp.) and fish food (Sera …

The Philippines, with an Exclusive Economic Zone (EEZ) of 2.2 million sq. km, including over 7,000 islands, relies on fisheries as one of its major industries, sources of employment and in promoting food security. The hand-line fishery using bancas (or pump boats), catching commercially viable species such as tuna, is a major component of both municipal and commercial fisheries in the Philippines. Hand-line fishing is considered one of the most sustainable forms of fishing in the country. However, the economic significance of the hand-line fishery is increasingly threatened by a number of factors, including poor information on the fishery and …
