Info

Each hemibranch bears many fine subdivisions called gill lamellae. It is the gill lamellae that form the major part of the sieve through which water passes. They are primarily responsible for creating the resistance to water flow <strong>and</strong> which represent the major respiratory portion of the gills. The total surface area of the gill lamellae averages about 5 cm 2 per gram of body weight.
In all bony fishes there are muscles that move the bases of the hemibranchs, that is, each holobranch can open <strong>and</strong> close. Water Water In this way, the tips of the hemibranchs of adjacent gill arches can come into contact with one another to create maximum resistance to water flow or they can be separated to protect the gills against excess water flow.
