| An upsurge in the prevalence of rusty-yellow discoloration of the skin of the two tilapia species, being cultured at the African Regional Aquaculture Centre (ARAC), gave a basis for an urgent clinical and epizootiological studies of the condition. The studies were therefore carried out along with the performance of some catfishes in polyculture with Oreochromis niloticus, under the integrated poultry cum fish farming system. It was observed that this condition affects the tilapia species only, and the antemortem, and postmortem examination revealed that the discolouration is restricted to the surface of the cutaneous tissue; affecting the underside of the exposed part of the scales, the fins and the skin flap covering the scale pockets, mostly in adult... |

| An epizootiological study of the mayor deseases affecting the penaeid shrimp Penaeus vannamei was performed from june 1994 throuh august, 1995 in tree farms located on the colombian Carebbean coast. The presence and prevalence of infectious agents such as bacteria, protozoa, viral inclusions bodies and changes histopatologicals was determinated by means of gross examination and histological analysis.. The relationship between these infection agents and specific disease was also studies. The presence of some viruses such a Baculovirus penaei, IHHNV, TSV and LOVV, were determinated by demostration of the cytopathical effects characteristic of these agent. Additionaly, a logistic regression analysis was used to determine the relationship between some clinical... |
