Abstract
This issue presents the shrimp production trends in Asia-Pacific, along with notes on the diseases devastating the industry and interviews with shrimp farmers in the Philippines. The options of shrimp farmers -- which are really quite limited and largely experimental - are discussed. These options include probiotics, the use of beta-glucans as immunostimulant, closed recycling systems. Farmers may also opt to farm other high-value species like grouper, mudcrab, or even milkfish to make use of the ponds they have invested quite a lot on.
This issue also discusses Philippine government efforts to revive the shrimp industry, as well as AQD's R&D priorities for shrimp as worked out in various consultations with AQD's program partners and industry practitioners.

Nutrient flow and physicochemical profile studies of an integrated poultry-salt-Artemia-milkfish-sea bass-shrimp pond production system
(Wetteren, Belgium: Universal Press, 1987)The physicochemical and biological parameters of an integrated flow-through poultry-salt-Artemia-milkfish-sea bass-shrimp pond production system were monitored for 6 months to determine the pattern of nutrient changes and associated plankton communities as water passed through the system. A 20 ha salt farm in Negros Oriental, Philippines, was used as a model of the integrated system. The construction of a poultry farm at the inlet reservoir provides continuous fertilization and allows considerable control of nutrient inputs to the pond system. Nutrients increase markedly in the chicken pond and in subsequent ponds undergo cycles of biological assimilation and bacterial mineralization. Principal component analysis ordinates temporal and spatial changes in 33 variables that were monitored. Using scatter diagrams of the principal components enabled separation of ponds adjacent to the crystallization bed and ponds high in fish biomass from the rest of the system. Variables that served to numerically delineate the ponds in this manner were salinity, phosphate, ammonia, alkalinity, turbidity, acidity, microplants, pico- and nannoplankton. The implications of this ordination in relation to pond management techniques is discussed. -
A further note to “fishing gear for prawn and shrimp used in the Philippines today”
(Carcinological Society of Japan, 1983)Motoh (1980) reported 9 and 13 kinds of shrimping gear for the fry and the adult respectively, of which most of them are indigenously used today in the Philippines. Howerver, druing the continued ecological survey of penaeids in the country conducted by him and his staff, six kinds of shrimping gear or devices were additionally found by them, which have been used traditionally in the country. The reasons that the present author intends to introduce the gear or devices are as follwos: 1) To record theses unque devices from the nature conservation point of view, which were invented by local people through their long experiences, though devices been forgotten due to their poor catching effectiveness, and 2) To recommend the continuous use of these devices by local people, which impose much less construction technique and energy on the users compared to modern mechanized catching tools.
