Melanophore sensitivity and pigmentation in fish exposed to medetomidine

, 2007
Pigment containing cells, melanophores, are abundant in scales and eyes of many fish species. The mobile pigment granules within these cells can be aggregated to give a pale appearance, or dispersed to give a dark appearance.

Highly efficient disruption of tyrb gene using CRISPR/Cas9 in grass carp (Ctenopharyngodon idella)

Reproduction and Breeding
Grass carp (Ctenopharyngodon idella) is the most important economic freshwater fish species in China. The stable production of high-quality grass carp depends significantly on excellent germplasm. In recent years, the generation of new germplasm based on

The Action of Ephedrine on Melanophores.

Experimental Biology and Medicine, 1930
Nadler1 found that in the squid, Loligo pealii, ephedrine injected subcutaneously, produced a local blanching which was considered as due to an inhibition of the smooth muscle of the chromatophore system and a generalized reddish coloration ascribed to a stimulation of the central nervous system.

A melanophore number QTL resides on Astyanax linkage group P09.

, 2013
The genetic architecture of the melanophore number trait in our cross yields a single strong QTL consistent with the predictions of breeding experiments, as previously described [18]. The x-axis depicts the relative positions of microsatellite markers on

Histological Structures of the Pseudobranch in Adult Mosquito Fish (Gambusia holbrooki Girard 1859)

Ibn Al-Haitham Journal for Pure and Applied Sciences
This paper deals with the histological structure of the pseudobranch of mosquito fish (Gambusia holbrooki), which lives in an Iraqi environment. The laboratory placed the adult fish, both male and female, in a fishbowl.

Re-expression of Kitlga, Csf1a, and Csf1b in bnc2 mutants promoted melanophore and xanthophore development but was insufficient for stripe patterning.

, 2013
(A) Melanophore recovery following heat-shock induction of Tg(hsp70l:kitlga). Although Kitlga expression increased melanophore numbers in bnc2 mutant larvae, the restored melanophores failed to develop into stripes.

Identification of larval stages of lantern fish in Iranian waters of Oman Sea

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2015
The fish larvae identification survey was carried out in Iranian waters of Oman Sea from Hormuz strait to Gwader Bay in 2009 at pre and post monsoon periods. Sampling was done by plankton net with 300 μ mesh size. Totally, 168 specimens were collected
