Brachyplatystoma is a genus of catfish from the family Pimelodidae. [1] As the occasionally used common name goliath catfishes indicates, this genus includes some of the largest species of catfish, including the piraíba, B. filamentosum, which reaches up to 3.6 metres (12 ft) in length; though the other species (and indeed most individuals of B. filamentosum) don't reach this length. [2]
Milt (sometimes spelled melt [1] [2]) or soft roe also refers to the male genitalia of fish when they contain sperm, used as food. Many cultures eat milt, often fried, though not usually as a dish by itself. As a food item, milt is farmed year-round in nitrogen tanks, through hormone induction or photoperiod control. [3]
The piraíba is notable for tackling difficult prey items, such as toxic Colomesus pufferfish and stingrays; armored catfish among the Doradidae and Loricariidae, such as Doras and Oxydoras; and other predatory fish like Pseudoplatystoma and Rhaphiodon are all taken by the piraíba, solidifying its position as top-order carnivore.
The channel catfish (Ictalurus punctatus), known informally as the "channel cat", is North America's most abundant catfish species. It is the official fish of Kansas, Missouri, Nebraska and Tennessee. The channel catfish is the most fished species of catfish in the United States, with around 8 million anglers angeling them per year
Edwardsiella ictaluri (also known as enteric septicaemia of catfish, hole in the head disease [2] and ESC) is a member of the family Hafniaceae. The bacterium is a short, gram negative , pleomorphic rod with flagella.
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.
Fish are fed daily through the summer, at rates of 1-6% of body weight with pelleted floating feed. Catfish need about two pounds of feed to produce one pound of live weight. Mississippi is home to 100,000 acres (400 km 2) of catfish ponds, the largest of any state. Other states important in growing catfish include Alabama, Arkansas and ...
Taste buds on the barbels tell the yellow bullhead whether or not contact is made with edible prey. They typically feed at night on a variety of plant and animal material, both live and dead, most commonly consisting of worms, [ 3 ] insects, snails, minnows, clams, crayfish, other small aquatic organisms, plant matter, and decaying animal matter.
