Lumpfish

 

(Cyclopterus lumpus), a fish of the family Cyclop-teridae. The lumpfish is usually 25–40 cm long (sometimes reaching 60 cm) and weighs up to 2–3 kg. The body is thick and covered with longitudinal rows of large bony tubercles. The ventral fins are converted into a sucking disk.

The lumpfish is distributed in the North Atlantic. It is a bottom-dwelling fish that stays in coastal waters. The fish attains sexual maturity in the third or fourth year. It spawns in the Barents and White seas from May through July. The female deposits from 79,000 to 136,000 large roe (2.7 mm) in the littoral zone. The roe, which are deposited in clusters in two or three stages, are guarded by the male. Lumpfish feed on benthic invertebrates. They are of minor commercial value: the roe, the liver, and the flesh are edible.

The morphology, variability, ultrasculpture and inferred growth of small dermal and other ossicles of Cyclopterus lumpus (lumpsucker) and Liparis liparis (sea snail) from the Baltic Sea can be compared with those seen in three genera and species (Triglopsis quadricornis--fourhorn sculpin, Myoxocephalus scorpius--shorthorn sculpin, Taurulus bubalis--longspined bullhead) of the related cottoid family Cottidae (sculpins) as described by Marss et al.
The conclusions of the study also show that minimal consumption of lumpsucker, hake or salmon roe satisfies the human body's Omega 3 essential fatty acid requirements, because of its levels of EPA y DHA.
