The principles and practice of statistics in macrobrafhium research. The relative quantity of food remaining in each container after the feeding was observed so that the ration size could be adjusted to minimize the waste.
Since there was no information related to the M.
Camarones de agua dulce de Venezuela II. Since plant protein meals are cheaper than animal protein sources, much research has been focused in substituting animal protein with the plant protein meals Akiyama, ; Kikuchi, The use of alternative protein sources in the culture of some crustacean species of commercial importance to reduce feed costs has been reported Akiyama, ; Piedad-Pascual et al.
Since there is no information on the possible use of soya bean meal in the formulated diets for the growth of M. The final specific growth fluctuated from 1.
Diets seemed equally palatable as determined by visual inspection 1 h after the feeding. Freshwater shrimps from Venezuela I: Enough water was added to make stiff dough.
Growth evaluation Individual standard length cm and wet weight g were determined at the beginning of the experiment and each two weeks for 45 days. The initial mean weight 0. It is accepted that soya bean meal is available worldwide and is cheaper than fish meal. FAO Fisheries Synopsis1, FCR among the diets detected at the end of the experiment was on average 1. Natantia “Smithsonian Contribution to Zoology” The SGR ranged from 1.
After arrival, the prawns were held in two L tanks and acclimate for one week to the laboratory conditions. A description of a new species of Macrobrachium from Peru, and distributional records for Macrobrachium brasiliensis Heller Crustacea: Statistical analysis was carried out according to Montgomery After failed attempts for developing a Giant Malaysian prawn M.
In conclusion, results indicate that the growth of M. Statistical analysis Statistical analysis was carried out according to Montgomery Macrobrachiun quelchi De Man and Euryrhynchus pemonin,sp.
In the formulated practical diets in the aquaculture, protein is the most expensive energy component, and its quality represents a very important nutritional aspect.
The mean SGR in the present study ranged from 1.
Effect of the concentration of nutrients in the culture medium. Procedures available in Statgraphics Plus 5. The data pertaining to mean body weight, length, SGR and survival are presented in Table 3.
Organisms were fed ad libitum two times daily Dietary protein was supplied by the Macrobrachiuum fish meal, soya bean meal or an isoproteic mixture of soya bean and fish meal, to obtain graded levels of each protein, as follows: However, the source and quality of the soya bean meal should be taken into consideration when a formulated diet is elaborated. Proceedings of the Biological Society of Washington98 3: Final survival per treatment was also recorded.
There mcrobrachium no reports on a specific diet for M. Acta Biologica Venezuelica13
