Improvement of productivity through breeding schemes

  title={Improvement of productivity through breeding schemes},
  author={Trygve Gjedrem},
The possibility to improve productivity in aquaculture by applying selective breeding and hybridization is very good. This is due particularly to large genetic variability in most economically important traits and high fecundity in species of interest. To increase efficiency, individual selection should be combined with family selection. It is concluded that if additive genetic variance is present in economically important traits, selection should be practiced, and if non-additive genetic… 

Genetic improvement in the Australian aquaculture industry

Most aquaculture industries in Australia are at an early stage of development and would benefit from the introduction of genetic improvement programmes, and the major research priority is the development of genetic markers to enable accurate pedigree determination.

Testing strategies for genomic selection in aquaculture breeding programs

Investigation of a general genomic selection scheme for aquaculture found rates of inbreeding were reduced by 81% in genomic selection schemes compared to traditional selection schemes for the parameters of the basic scheme, due to within-family selection.

Cost-benefit analysis of aquaculture breeding programs

The baseline breeding program was profitable after 5 years and reached a net present value of 2.9 million euro in year 10, and the optimum number of selection candidates increased with the length of the time horizon and production output, so avoiding the use of a multiplier tier will increase the profitability of the breeding program in the short term.

The use of communal rearing of families and DNA pooling in aquaculture genomic selection schemes

This new selection scheme combines communal rearing of families, pre-selection of candidates, DNA pooling and genomic selection and makes multi-trait selection possible in aquaculture selection schemes without keeping families separately until individual tagging is possible.

Selection and crossbreeding in Mediterranean cultured marine fish

Gain from selection for increase weight was attributed to increased food conversioenf ficiency, and mass selection rather than family selection, was technically possible for the group spawning S. aurata.

Flesh quality improvement in fish through breeding

There is an unfavourable genetic correlation between body weight and the traits fat percentage and area of fat depot, and the expected response to selection in quality traits varies between 5 and 15% per generation.

Principles of finfish broodstock management in aquaculture: control of reproduction and genetic improvement

The chapter explains the bases of setting up a genetic improvement program and identifies the associated benefits and risks of this long term investment.

Past, present, and future of genetic aquaculture improvement in salmon 0 AP

The farming of Atlantic salmon has become an important industry in several countries, and breeding programmes have been implemented to improve genetic performance and adaptation to farm environments.



Possibilities for Genetic Improvements in Salmonids

The very high fertility in salmonids makes it possible to practice an intensive selection for fish in captivity and a more moderate selection in wildlife cultivation.

Comparison of crossbred and purebred selection for a heterotic trait in highly selected populations of Tribolium.

A model for the genetic control of larval weight is suggested in which there are both dominant and overdominant loci and homozygotes are less fit than heterozygotes.

Genetic differences between the Chinese and European races of the common carp

The European and Chinese races of the common carp and their F1 crossbreds were tested in five experimental environments and genetic differences in terms of selection response to the different fish-farming practices that existed in the two regions were advanced.


The authors compare the theoretical consequences of three fairly simple ways of selecting for net merit, considered as a compound of several different characteristics, and find the method of total score is most efficient, while the tandem method is the least efficient of the three.

Development of a synthetic pig sire line by selection with immigration 1. Results of selection and heritability estimates

In Generation 11, a centrally tested sample of the Sire Line showed significant improvements over contemporary Large Whites in growth rate, feed efficiency, eye-muscle area, lean percentage and some fat depths, but was significantly worse in killing-out percentage.
