Gastric emptying in cod, Gadus morhua L.: emptying and retention of indigestible solids
Particles 2 mm or smaller may be passed relatively easily through the pylorus of the cod, Gadus morhua L., but, under some conditions, 5 mm particles are held in the stomach for prolonged periods. The emptying of indigestible particles appears to be impaired by the consumption of additional meals, a...

| Summary: | Particles 2 mm or smaller may be passed relatively easily through the pylorus of the cod, Gadus morhua L., but, under some conditions, 5 mm particles are held in the stomach for prolonged periods. The emptying of indigestible particles appears to be impaired by the consumption of additional meals, and prolonged retention of these particles may occur in fish fed multiple meals. The findings agree in general with those reported for mammals and the results are discussed in relation to mechanisms thought to control gastric motor activity patterns. |
