Abstract
In the last years, one can notice an intensification tendency of the aquaculture production, which supposes the usage of a high quality biological population material. This is possible only by using a protein fodder that corresponds to all the physiological needs of the breed and which is economically efficient.
The purpose of this experiment was to test the efficiency of in the intensive system of carp raising (Cyprinus carpio). By the studies realized one aimed at a biological evaluation of the fodders through general methods based on using some bio-productive indicators - the raise rhythm (Sr), the fodders conversion coefficient (FCR), the specific raise percent (SGR) and the efficiency coefficient of the protein (PER).
The experiment took place in four tanks belonging to the C.C.D.P. Nucet, in three raising variants. We considered using traditional fodder compared with two types of protein fodder - type ALLER (32 % protein) and type Soprofish (25 % protein). The daily fodder ratio was established at 2,5 % of the juvenile fish weight.
When was inhabited, the used fish had an average weight of 74,5±3,8g, and afther 120 days of rearing, the biggest final average body moss was of 2286,2g/ex andwas recorder for thebatch that received in food Soprofish.
Comparatively whit the other batches this one was the efficiency of using protein fodders.

Rezumat
In ultimii ani, se constata o tendinta de intensivizare a productiei din acvacultura ce presupune utilizarea unui material biologic de populare de calitate superioara. Acest lucru este posibil numai prin folosirea unui furaj proteic care sa corespunda necesitatilor fiziologice ale speciei si sa fie eficient din punct de vedere economic.
Scopul acestui experiment a fost acela de a testa eficienta utilizarii diferitelor tipuri de furaje proteice, comparativ cu folosirea furajului traditional în sistem intensiv la cresterea crapului (Cyprinus carpio). Prin studiile realizate s-a urmarit evaluarea biologica a furajelor prin metode generale bazate pe utilizarea unor indicatori bioproductivi - ritmul de crestere (Sr), coeficientul de conversie al furajelor (FCR), rata cresterii specifice (SGR) si coeficientul de eficienta al proteinei (PER).
Experimentul s-a realizat în patru bazine apartinând C.C.D.P. Nucet, în trei variante de crestere. S-a avut în vedere utilizarea furajului traditional comparativ cu doua tipuri de furaj proteic tip ALLER (30 % proteina) si tip Soprofish (25 % proteina). Ratia zilnica de furaj a fost stabilita la 2,5 % din greutatea puietului.
La populare materialul piscicol utilizat avea o greutate medie de 74,5±3,8 ,iar dupa 120 de zile de crestere greutatea medie finala cea mai mare a fost de 2286,2g/ex si s-a inregistrat la lotul care a primit in alimentatie Soprofish.
Comparativ cu celelalte loturi acesta a demonstrat eficienta utilizarii furajelelor proteice.
