Conference paper- In JR Arthur, CR Lavilla-Pitogo & RP Subasinghe (Eds.), Use of Chemicals in Aquaculture in Asia : Proceedings of the Meeting on the Use of Chemicals in Aquaculture in Asia 20-22 May 1996, Tigbauan, Iloilo, Philippines, 2000 - Aquaculture Department, Southeast Asian Fisheries Development CenterMany aquaculture chemicals are, by their very nature, biocidal, and may be released to the surrounding environment at toxic concentrations either through misuse, or in some cases, even by following generally accepted procedures for use. Thus, there is a potential for mortality of nontarget organisms. Illustrations are provided of three classes of aquaculture chemicals and their effects on non-target biota: 1) use of a carbaryl pesticide and mortality of non-target invertebrates; 2) use of an organophosphate parasiticide and suspected effects on nearby biota; and 3) effects of antibacterial residues in aquatic sediments on the associated microbial community. Efforts to assess the risks posed by aquaculture chemicals are often frustrated by a lack of information on environmental fate and effects, and data needs to resolve this situation are identified.
Isolation and identification of Pseudomonas fluorescens from hatchery-reared tilapia fry (Oreochromis niloticus Linnaeus) -
SEAFDEC Asian Aquaculture, 1988 - Aquaculture Department, Southeast Asian Fisheries Development Center
Researches on Crustacea, 1984 - Carcinological Society of JapanThirty-five species of penaeoid prawns, representing 9 genera in 3 families, have been found over a period of 5 years from 1976 to 1980 in the Philippine waters. Of these, 15 species have been recorded for the first time from the country. Keys for the identification of genera and species, and descriptions as well as illustrations of 35 species except for the illustration of Metapenaeus moyebi are provided. Twelve species out of the 35 species are commercially important. They are Metapenaeus anchistus, M. dalli as well as M. moyebi, M. ensis, Penaeus indicus, P. japonicus, P. latisulcatus, P. merguiensis, P. monodon, P. semisulcatus, Solenocera alticarinata, and S. melantho, of which P. monodon is the greatest because of its large size, abundant occurence of the fry and easier cultivation in the pond, and furthermore, other five Penaeus species are of great potential for an aquaculture in brackishwater fishponds.
