Recent results show a striking similarity in the dynamics of expression of gonad differentiation regulators in zebrafish and mammals. Candidates for the role of master key regulators (MKRs) in tilapia were selected, based ...

At the National Center for Cool and Cold Water Aquaculture (US Department of Agriculture, Ag. Research Service) in Leetown, WV, we have a broodstock development program now entering the second generation of family-based ...

The history of selective breeding in the US catfish industry is reviewed. The failures and suc- cesses of technology and germplasm transfer for catfish genetic enhancement are discussed.

Investment in breeding is unique because genetic gains are eternal and cumulative. They are never “used up”, and never “wear out”. However, nearly all of the gain is transferred to the national economy. Very little stays ...

The aim of this review is to show the progress and achievements made to date in the selective breeding of cultured marine fish in Israel. The National Center for Mariculture (NCM) in Eilat was the first scientific organization ...

Progress in recombinant DNA technology and development of new expression systems has provided valuable means to produce large quantities of hormones and growth factors from various fish species that otherwise required ...

Ploidy manipulation was introduced to Israel at the beginning of the 1980s. To improve existing methods, Israeli fish centers conducted intensive research in this field for more than two decades. Chromosome-set technology ...

The first selective breeding programs for aquaculture species that also used sib information in the selection decisions were established in the early 1970s for Atlantic salmon and rainbow trout. Presently there are a total ...

Sequencing of expressed sequence tags (ESTs) has been one of the primary techniques used for transcriptome analysis in a wide spectrum of species including those utilized for aquaculture. However, many researchers are still ...

Development of molecular genetic markers provides aquaculture with tools for a number of research and practical applications. Genetic marking of experimental groups allows their evalu- ation in the same rearing units, ...
