WebOsmosis refers to the flow of solutes from high concentration (salty; high osmotic pressure) to low concentration (dilute; low osmotic pressure). Many saltwater fish osmoregulate by active excretion of salt through the gills and salty urine. This allows the fish to maintain lower salt concentration in its body than in the surrounding saltwater. http://utmadapt.openetext.utoronto.ca/chapter/4-1/

Osmoregulation and Osmotic Balance Boundless Biology
WebOsmoregulation in Freshwater Fish; Freshwater fishes are hypertonic to their surrounding environment, which means that the concentration of salt is higher in their blood than … WebTo combat this, marine fish intake more water and they filter out excess salt in their kidneys and gills. Similarly, freshwater is hypotonic to freshwater fish, meaning that water is being pushed into the skin. This is due to a higher concentration of water in the surrounding water. Fish combat this by urinating more frequently. Two major types of osmoregulation are osmoconformers and osmoregulators. Osmoconformers match their body osmolarity to their environment actively or passively. Most marine invertebrates are osmoconformers, although their ionic composition may be different from that of seawater. In a strictly osmoregulating animal, the amounts of internal salt and water are held relatively constant in th… how to start your novel
