“…Shiba (1982) removed the distal half of the barbel in bronze cory catfish ( Corydoras aeneus ) and observed a renewed appendage with taste bud structures in 2–3 weeks. More recently, barbel amputation was attempted as a mark-recapture technique for juvenile shortnose sturgeon ( Acipenser brevirostrum ); however, it was observed that many of the severed barbels completely or partially regrew, making this approach inappropriate for long-term studies [35] , [36] . Although catfish and sturgeon barbels are not structurally identical to zebrafish barbels, nor are these structures necessarily homologous, these reports suggested to us that barbel regeneration might be evolutionarily conserved.…”

BackgroundBarbels are integumentary sense organs found in fishes, reptiles and amphibians. The zebrafish, Danio rerio, develops paired nasal and maxillary barbels approximately one month post fertilization. Small in diameter and optically clear, these adult appendages offer a window on the development, maintenance and function of multiple cell types including skin cells, neural-crest derived pigment cells, circulatory vessels, taste buds and sensory nerves. Importantly, barbels in other otophysan fishes (e.g., catfish) are known to regenerate; however, this capacity has not been tested in zebrafish.Methodology/Principal FindingsWe describe the development of the maxillary barbel in a staged series of wild type and transgenic zebrafish using light microscopy, histology and immunohistochemistry. By imaging transgenic zebrafish containing fluorescently labeled endothelial cells (Tg(fli1a:EGFP)), we demonstrate that the barbel contains a long (∼2–3 mm) closed-end vessel that we interpret as a large lymphatic. The identity of this vessel was further supported by live imaging of the barbel circulation, extending recent descriptions of the lymphatic system in zebrafish. The maxillary barbel can be induced to regenerate by proximal amputation. After more than 750 experimental surgeries in which approximately 85% of the barbel's length was removed, we find that wound healing is complete within hours, followed by blastema formation (∼3 days), epithelial redifferentiation (3–5 days) and appendage elongation. Maximum regrowth occurs within 2 weeks of injury. Although superficially normal, the regenerates are shorter and thicker than the contralateral controls, have abnormally organized mesenchymal cells and extracellular matrix, and contain prominent connective tissue “stumps” at the plane of section—a mode of regeneration more typical of mammalian scarring than other zebrafish appendages. Finally, we show that the maxillary barbel can regenerate after repeated injury and also in senescent fish (>2 years old).Conclusions/SignificanceAlthough the teleost barbel has no human analog, the cell types it contains are highly conserved. Thus “barbology” may be a useful system for studying epithelial-mesenchymal interactions, angiogenesis and lymphangiogenesis, neural pathfinding, wound healing, scar formation and other key processes in vertebrate physiology.

“…Future hatchery programmes should incorporate active and adaptive learning approaches to minimize the risks associated with artificial propagation and to promote sustainable Mahisefid stocks. Tagging system can help to confirm of study (Fadaee et al 2006). They should avoid to produce hybrid of Mahisefid with other species that had done before by Zamini et al (2006) and if done haven't to release in the wild (Bartley et al 2001).…”
