A cod hatching plant was established in 1992 on the island of Bornholm in the Baltic Sea in order to elucidate the possibilities for restocking of cod fry in this brackishwater system. The disease prevalence in 3 batches of hatchery-reared yolksac larvae from the Baltic cod (Gadus morhua L.) was monitored during the posthatch period. High prevalences of bacteriosis/mycosis, lordosis/scoliosis, injuries and protozoan endoparasitism were recorded. Vibrio sp. and Vibrio anguillarum serovar 04, 06, 08 in addition to nontypable strains and saprolegniaceous fungi were isolated from the larvae. The dinoflagellate-like endoparasites were located in the yolksac of the cod larvae.
1992年，在波罗的海的博恩霍尔姆岛建立了一个鳕鱼孵化场，以阐明在这个半咸水系统中补充鳕鱼鱼苗的可能性。在孵化后的时期内，对来自波罗的海鳕鱼（Gadus morhua L.）的3批孵化场饲养的卵黄囊幼虫的疾病流行情况进行了监测。记录到了高比例的细菌病/霉菌病、脊柱前凸/脊柱侧凸、损伤和原生动物体内寄生虫感染。从幼虫中分离出了弧菌属、鳗弧菌血清型04、06、08，以及无法分型的菌株和水霉属真菌。类似甲藻的体内寄生虫位于鳕鱼幼虫的卵黄囊中。
