The aquatic equivalent to smelling in air is tasting in water. Many larger catfish have chemoreceptors across their entire bodies, which means they "taste" anything they touch and "smell" any chemicals in the water. "In catfish, gustation plays a primary role in the orientation and location of food". [14] Salmon have a strong sense of smell.
Water bodies are often affected by geosmin and 2-methylisoborneol, affecting the flavour of water for drinking and of fish growing in that water. [1] Haloanisoles similarly affect water bodies, and are a recognised cause of off-flavour in wine. [2] Cows grazing on weeds such as wild garlic can produce a ‘weedy’ off-flavour in milk. [3]
Gafftopsail catfish are good eating; the red lateral line should be removed to prevent "muddy taste"; however in gafftopsails taken from southern Florida mangrove estuaries, this is seemingly unnecessary. The pectoral fins and dorsal fin contain venomous spines; care should be used when handling this fish.
Milt is the seminal fluid of fish, mollusks, and certain other water-dwelling animals. They reproduce by spraying this fluid which contains the sperm, onto roe (fish eggs). It can also refer to the sperm sacs or testes that contain the semen.
The wels catfish lives in large, warm lakes and deep, slow-flowing rivers. It prefers to remain in sheltered locations such as holes in the riverbed, sunken trees, etc. It consumes its food in the open water or in the deep, where it can be recognized by its large mouth. Wels catfish are kept in fish ponds as food fish.
The flathead catfish cannot live in full-strength seawater (which is about 35 parts per thousand or about 35 grams of salt per liter of water), but it can survive in 10 ppt for a while and thrive in up to about 5 ppt. [12] Flathead catfish are a benthic fish species meaning they are a fish which prefers to lay on the bottom of a body of water.
Similar to wine, “water is actually 100% terroir driven,” meaning a particular region’s climate and soil where the water is sourced affect its taste, explains Riese. “You can actually ...
The hardhead catfish has four barbels under the chin, with two more at the corners of the mouth. [8] These barbels help the catfish find crabs, fish, and shrimp in the muddy or sandy bays where they live. The head is slightly flattened and conceals a hard plate between the eyes and dorsal fin.
