Henneguya aequidens occurred in 33.3% of the gills of Aequidens plagiozonatus individuals (VIDEIRA et al., 2015); whereas in Arapaima gigas, Henneguya arapaima parasitized the
gill arches and gall bladder with a prevalence of 11.7% and 82.3%, respectively (FEIJO et al., 2008).
a) Trichodinids in a fresh-mounted smear from the
gill arches, b) differential interference contrast microscope, c) an adhesive disc of Trichodina in silver nitrate impregnation, d) T.
Mandible, ceratobranchial, cleithrum and
gill arches were the initial skeletal structures appeared at 3 DPH that supported the vital life functions such as feeding and respiration.
Prior to the observation of the parasites location on the gills, arbitrary division of the
gill arches was made according to Turgut et al.
We follow how the rakers change from the 1st to 4th
gill arches in three flatfish taxa and how some features change during ontogeny.
The diameters of gill opening as well as the length of
gill arches were measured; the numbers of
gill arches and gill rakers were detected.
The next morning we euthanized the fish by cervical separation and removed the
gill arches and placed them in 300 pL 0.4% KCl.
In addition, many fish have taste buds on the gills, throat, gullet,
gill arches and even between the teeth, while some species have taste buds outside the mouth.
The lower jaw, teeth, and Meckel's cartilage develop when cells of the cranial neural crest (CNC), which give rise to the dorsal neural tube, migrate into the
gill arches (1-3).
The gills were removed and the
gill arches were separated, placed in vials and filled with hot water (60 to 70[degrees] C).
