Application of selection methods by independent boarders and a selection index at generation of belarussian mirror carp breed

There are presented the selection methods of repair junior groups of selected Belarussian mirror carp by independent borders and a selection index . It is suggested to apply the the selection methods by independent borders for phenotypical, exterior propeties and selection be selection indices by the complex of fishery indices, respectively.Представлены методы отбора младших групп ремонта селекционируемого белорусского зеркального карпа по независимым границам и селекционному индексу. Метод отбора по независимым границам предлагается использовать для фенотипических, экстерьерных признаков, а отбор по селекционным индексам – по комплексу рыбохозяйственных показателей

At the result of comparative analysis of fishery indice of the 1 generation of one year old fishes of two breeding lines of Belarusian mirror carp represented by 18 families there were discovered the most productive groups which are distinguished with increased growing rate and survivability.В результате сравнительного анализа рыбохозяйственных показателей сеголетков I генерации двух селекционных линий белорусского зеркального карпа, представленных 18 семьями установлены наиболее продуктивные группы, которые отличаются повышенным темпом роста и выживаемостью

Morphometrical indicators of trout underyearlings of various origin

There is provided a description of exterior morphometrical properties of trout underyearlings taken from two populations imported from the Russian Federation and France at the phase of impregnated row. There were discovered the differences between the underyearlings of various origin in terms of absolute and relative properties.Представлена характеристика экстерьерных морфометрических признаков сеголетков форели из двух популяций, завезенных на стадии оплодотворенной икры из России и Франции. Установлены различия сеголетков разного происхождения по ряду абсолютных и относительных признаков

Comparison characteristics of interior properties of Belarussian trout breeding Populations replacement

There were presented the comparison results of relative weights of trout females and males body parts from two populations adapted to the conditions of Belarus generated from the genetic material imported to Belarus.Представлены результаты сравнения относительных масс частей тела самок и самцов форели из двух популяций, адаптированных к условиям Беларуси, сформированных из завезенного в республику генетического материала

Evaluation of reproduction properties of different carp breeds female and perspective of selection material forming with increased breeding perfomance

Isobelino carp branch genesial parameters study has revealed avai lability of high variability between families in each branch regavding fertility, survival rate of eggs and larvas. The existence of variability between families allows to conduct selektion according to genesial parameters when creating new carp breeds

Comparative characteristic of the Tremlya carp crosses for the toxic tolerance

We are creating the Tremlya carp breed considering it's rearing in conditions of the Polessie plain, which are characterized with big concentration of the iron solute in water. This factor has adverse effect on the survival rate of the fish, especially at the early stages of the development. Therefore, the assessment of the different crosses for the tolerance to this adverse factor is very important. In the result of the conducted work we found the crosses that were more tolerant to the higher concentration of the iron solute in water

Comparison characteristic of nutritional value of cross group with tremliansky carp

The article provides the comparison characteristic of relative mass of body parts (nutritional value) of crosses obtained through reciprocal crossings of scaly and mirror lines of tremlianski carp with the imported and belorussian breeds. There were identified some crossing combination advantages of mirror line with the imported breeds

Reproductive properties сharacteristics of trout spawners from Belarussian genetic pool

It was ascertained that the brood material of rainbow trout available in the Republic of Belarus represents the valuable genetic material adapted to the conditions of fish breeding farms of Belarus quite capable of producing proper offspring. There are defined reproductive properties of selected ensemble (25 females) of rainbow trout. There was ascertained the correlation dependence between a female body weight and its industrial fecundity.Определено, что имеющийся в республике племенной материал радужной форели представляет собой ценный генетический материал, прошедший адаптацию к условиям рыбоводных хозяйств Беларуси, способный давать полноценное потомство. Дана характеристика воспроизводительных качеств выборочной совокупности (25 самок) радужной форели. Установлена корреляционная зависимость между массой тела самки и ее рабочей плодовитостью
