Effects of Hypoxia-Induced Gill Remodelling on the Innervation and Distribution of Ionocytes in the Gill of Goldfish, Carassius auratus
The presence of an interlamellar cell mass (ILCM) on the gills of goldfish acclimated to 7°C leads to preferential distribution of branchial ionocytes to the distal edges of the ILCM, where they are likely to remain in contact with the water and hence remain functional. Upon exposure to hypoxia, the ILCM retracts, and the ionocytes become localized to the lamellar surfaces and on the filament e...
متن کاملThe consequences of reversible gill remodelling on ammonia excretion in goldfish (Carassius auratus).
Goldfish acclimated to cold water (e.g. 7°C) experience a marked reduction in functional lamellar surface area owing to the proliferation of an interlamellar cell mass (ILCM), a phenomenon termed gill remodelling. The goal of the present study was to assess the consequences of the reduced functional surface area on the capacity of goldfish to excrete ammonia. Despite the expected impact of ambi...

متن کاملThe control of breathing in goldfish (Carassius auratus) experiencing thermally induced gill remodelling.
At temperatures below 15°C the gill lamellae of goldfish (Carassius auratus) are largely covered by an interlamellar cell mass (ILCM) which decreases the functional surface area of the gill. The presence of the ILCM in goldfish acclimated to cold water conceivably could lead to a covering of the neuroepithelial cells (NECs), which are believed to be important for sensing ambient O₂ and CO₂ leve...
متن کاملThe interactive effects of hypoxemia, hyperoxia, and temperature on the gill morphology of goldfish (Carassius auratus).
Acclimation of crucian carp and goldfish to temperatures below 15°C causes covering of the gill lamellae by a mass of cells termed the interlamellar cell mass (ILCM). Here we explore the cues underlying gill remodeling (removal or growth of an ILCM) and specifically test the hypotheses that 1) depletion of internal O(2) stores in the absence of any change in external O(2) status can trigger the...
