BRAZILIAN PUBLICATIONS ON MACROBRACHIUM ROSENBERGII (DE MAN), A FRESHWATER SHRIMP. 2. LIST BY SUBJECT

Abstract

The aim of this study was to continue the diagnosis of the Brazilian publications, performed by a member of the Working Group on Freshwater Prawn Farming (GTCAD), Macrobrachium rosenbergii. A preliminary list was presented during Brazilian Aquaculture Congress, in 1994 (VIII SIMBRAq) and was then updatted and reorganized by subject. The Brazilian references on freshwater prawn are those currently filed at the Aquaculture Sector of the Zootechny Department of the Federal University of Rio Grande do Sul State (Setor de Aquacultura do Departamento de Zootecnia da Faculdade de Agronomia da UFRGS). This current version has its citations distributed in to six main categories: 1. management, culture systems and phases; 2. Feed and feeding (nutrition); 3. physiology, endocrinology, genetics, diseases and parasitism; 4. policulture and consorcium; 5. water and soil quality; and 6. post-harvest, processing and commercialization. It was classified 70 references on the category 1. management, culture systems and phases, most of them (23) related to economic analysis, reports, diagnosis and up-to-date reports of the activity in different States of Brazil, being the researches on growth phases more numerous (16) then hatchery (12), general biology (10) and finally the nursery phase (9). 2. Feed and feeding (nutrition): out of 46 citations, 30 were about feeding management on the nursery phase, 16 for adults and none for larvae. The item 3. physiology, endocrinology, genetics, diseases and parasitism of main importance on the economic feasibility in prawn culture, presented only 14 papers, most of the basic research performed on the reproduction and hatchery phase. The topic 4. policulture and consorcium brought 7 references, and the item 5. water and soil quality had only 3 citations, the same number of the topic 6. post-harvest, processing and commercialization, one of the medular point for the success of the activity in Brazil. From the present study, it can be assumed that efforts must be redirected in a way to avoid the great disproportionality of work among different subjects of the main topics of research on Brazilian freshwater prawn.
