temporal variation and characterization of grunt sounds produced by atlantic cod gadus morhua and pollack pollachius pollachius during the spawning season.fine-scale temporal patterning in grunt production and variation in grunt attributes in atlantic cod gadus morhua and pollack pollachius pollachius was examined. pollachius pollachius produced only a single sound type, the grunt, similar to that previously described for g. morhua. sound production and egg production were correlated in p. pollachius but not in g. morhua. only g. morhua displayed a strongly cyclical pattern, producing more grunts at night. finer-scale temporal patterning in grunt ...201424646040
new data on the early development of hysterothylacium aduncum (nematoda, anisakidae).this note reports on incidental observations of the early development of the third-stage larvae of hysterothylacium aduncum from gadid fishes. gravid h. aduncum females were collected from pollachius virens, pollachius pollachius. gadus morhua, and molva molva in norwegian waters. the eggs were incubated at 20 per thousand salinity and 5 c. spontaneous hatching of third-stage larvae was observed 10-25 days after egg deposition. these larvae were long lived and could infect acartia tonsa copepods ...19989645866
cholinergic and adrenergic influence on the teleost heart in vivo.the tonical cholinergic and adrenergic influence on the heart rate was investigated in vivo in seven species of marine teleosts (pollack, pollachius pollachius; cuckoo wrasse, labrus mixtus; ballan wrasse, labrus berggylta; five-bearded rockling, ciliata mustela; tadpole fish, raniceps raninus; eel-pout, zoarces viviparus and short-spined sea scorpion, myoxocephalus scor pius) during rest and, in two of the species (p. pollachius and l. mixtus), also during moderate swimming exercise in a blazka ...19873582588
screening and characterisation of potentially pathogenic bacteria associated with atlantic cod gadus morhua larvae: bath challenge trials using a multidish system.in intensive aquaculture systems, high concentrations of nutrients and high densities of fish larvae provide favorable conditions for opportunistic pathogenic bacteria to flourish. we screened potentially pathogenic bacterial strains isolated from moribund atlantic cod gadus morhua larvae, pollack pollachius pollachius, coalfish pollachius virens, atlantic halibut hippoglossus hippoglossus, rotifers, algae and water samples from different hatcheries. three identical challenge experiments tested ...200818998585
involvement of methemoglobin (methb) formation and hemin loss in the pro-oxidant activity of fish hemoglobins.the capacity of atlantic pollock ( pollachius pollachius ), seabass ( dicentrarchus labrax ), and horse mackerel ( trachurus trachurus ) hemoglobin (hb) to promote lipid oxidation has been evaluated in liposomes and washed minced horse mackerel muscle. the pro-oxidant ability of fish hbs was related with their vulnerability to suffer oxidation to methb and release hemin either in spontaneous situation or in the presence of two representative lipid oxidation products, linolein hydroperoxides and ...200919722582
acoustic basis for fish prey discrimination by echolocating dolphins and porpoises.the biosonar system of dolphins and porpoises has been studied for about 5 decades and much has been learned [au, w. w. l. (1993). the sonar of dolphins (springer, new york)]. most experiments have involved human-made targets; little is known about odontocetes' echolocation of prey. to address this issue, acoustic backscatter from atlantic cod (gadus morhua), gray mullet (chelon labrosus), pollack, (pollachius pollachius), and sea bass (dicentrarchus labrax) was measured using simulated biosonar ...200919603903
anisakidae larval infection in fish fillets sold in belgium.fish fillets (n = 1760) sold on the belgium market were examined for anisakidae larval infection. seven sea fish species were examined by means of the candling technique over a period of 4 months, from november 1996 to february 1997. third-stage larvae of anisakis simplex and pseudoterranova decipiens were identified. a. simplex was the most abundant species with a prevalence of 84.5%, and was found in 192 of the examined fillets (10.9%). pollock (pollachius pollachius) was the most heavily infe ...199910321017
