【摘要】：目的了解煙臺市市售海魚感染異尖線蟲(Anisakis spp.)幼蟲的情況。方法2016年1月至12月,在煙臺市各海鮮市場隨機采購不同種類的海魚,解剖魚體,查找、分離內臟和肌肉中的異尖線蟲幼蟲,光學顯微鏡下鑒定蟲種,統(tǒng)計分析不同魚種、不同臟器和不同體質量下異尖線蟲幼蟲的感染情況。結果共解剖海魚14種256尾,海魚異尖線蟲幼蟲總感染率為66.4%(170/256),平均感染度為14.8條/尾。感染率較高的魚種有鮐魚(Pneumatophorus japonicus)、帶魚(Trichiurus lepturus)、辮子魚(Platycephalus indicus)和黑湭(Sebastodes fuscescens)等,感染率分別是100%(26/26)、92.3%(24/26)、92.0%(23/25)、85.7%(18/21),平均感染度分別為25.1、21.1、12.2和24.9條/尾;其他魚種感染率由高到低依次是海鰻(Monopterus albus,80.0%,6.3條/尾)、真燕鰩(Prognichthys agooz,70.0%,3.3條/尾)、小黃魚(Larimichthys polyactis,66.0%,11.7條/尾)、藍點馬鮫(Scomberomorus niphonius,52.0%,9.1條/尾)、高眼鰈(Cleisthenes herzensteini,50.0%,1.8條/尾)、鯡魚(Clupea pallasi,44.4%,9.5條/尾)和黑背圓頜針魚(Tylosurus melanotus,38.1%,2.0條/尾);銀鯧(Pampus argenteus)、綠鰭馬面渶(Thamnaconus modestus)、海鱸魚(Perca fluviatilis)未檢出異尖線蟲幼蟲。異尖線蟲幼蟲多寄生于海魚的腸系膜及腸壁、體腔和胃壁。不同魚種的異尖線蟲幼蟲感染度與其體質量的相關性不同:體質量為0.25~0.35 kg的鮐魚、0.16~0.20 kg的帶魚、0.16~0.25 kg的辮子魚、0.05~0.10 kg的小黃魚、0.17~0.26 kg的黑湭、0.81~1.00 kg的藍點馬鮫的感染度較高,分別為46.5、27.2、18.0、12.0、42.7和68.0條/尾。在這6種魚中,黑湭和小黃魚的感染度隨體質量的增加而降低(r=-0.484,P0.05;r=-0.633,P0.01),藍點馬鮫的感染度隨體質量的增加而增高(r=0.740,P0.01),鮐魚、帶魚、辮子魚感染度與體質量無相關關系(r=-0.237、-0.080、-0.196,均P0.05)。結論煙臺市售海魚中,鮐魚、帶魚、辮子魚和黑湭的異尖線蟲幼蟲感染率較高(85%以上)。
[Abstract]:Objective to investigate the (Anisakis spp.) infection of sea fish in Yantai city The condition of the larva. Methods from January to December 2016, different species of marine fish were randomly purchased in the seafood market of Yantai City. The fish bodies were dissected, the larvae of heterocephalous nematode were isolated from viscera and muscle, and the species were identified under optical microscope, and different species of fish were analyzed statistically. Infection of nematode larvae in different organs and different body mass. Results A total of 256 marine fishes were dissected. The total infection rate was 66.4% (170 / 256) and the average infection degree was 14.8 / tail. The species with higher infection rate were (Platycephalus indicus) and (Sebastodes fuscescens), respectively. The infection rates were 100% (26 / 26), 92. 3% (24 / 26), 92. 0% (23 / 25), respectively, the infection rates were 100% (26 / 26), 92. 3% (24 / 26), 92. 0% (23 / 25), respectively. 85.7% (18 / 21), the average infection degree was 25.1T 21.1T 12.2 and 24.9 / tail, respectively. The infection rates of other species from high to low were eel (Monopterus albus,80.0%,6.3 / tail), true swallow ray (Prognichthys agooz,70.0%,3.3 / tail), small yellow croaker (Larimichthys polyactis,66.0%,11.7 / tail), Blue spot mackerel (Scomberomorus niphonius,52.0%,9.1 / tail), halibut (Cleisthenes herzensteini,50.0%,1.8 / tail), herring (Clupea pallasi,44.4%,9.5 / tail) and Tylosurus melanotus,38.1%, 2.0 / tail); The larva of heterodendron nematode was not detected in (Thamnaconus modestus), sea bass (Perca fluviatilis). The larvae of Heterostrongylus are parasitic on the mesenteric and intestinal wall, body cavity and stomach wall of marine fish. The correlation between the larval infection degree and body weight of different species of nematode was different: mackerel with body weight of 0.25 kg, hairfish with 0.160.20 kg, braided fish with 0.160.25 kg, small yellow croaker with 0.05 kg 0.10 kg. The infection rates of 0.17m 0.26 kg and 0.81g 1.00 kg were higher, 42.7 and 68.0 / tail, respectively. In these six species, the infection degree of black croaker and small yellow croaker decreased with the increase of body mass (r = -0.484, P 0.05); The infection degree of blue spot mackerel increased with the increase of body mass (r = 0.740, P 0.01). There was no correlation between infection degree and body mass of mackerel, hairpin, braided fish (r = 0.237- 0.080 / 0.196). P 0.05). Conclusion in Yantai, the infection rate of the larvae of sea fish, mackerel, hairfish, braided fish and Acanthopteris nigra is higher (more than 85%).
