Food microorganisms are found on all surfaces (skin and gills) and in the intestines of fishery products.[...].

Mass mortality occurred in 2-year-old koi (fancy carp)Cyprinus carpio in Taiwan in 2002. Affected fish did not show any external signs except swollen gills. The consistent histological changes were observed in the gills; hyperplasia of epithelial cells, infiltration of eosinophilic granular cells and fusion of the secondary lamellae. Nega tively stained nucleocapsids were icosahedral and 112±1 ...

A new species of Tripartiella is described from the gills of the wild saddle cichlid Aequidens tetramerus in north Brazil. Wet smears of skin and gills of examined fish were air-dried at room temperature and impregnated with Klein's dry silver method for examination of the adhesive disc's structures and denticles. Total prevalence of parasitism was 65%. This ciliate is characterized as a small-...

Myanmarorchestia Hou, gen. n. with two new species is described from terrestrial habitats in Myanmar. This new genus is characterised by 4-dentate lacinia on left mandible, simple gnathopod I in both sexes, weakly chelate gnathopod II in male, simplidactylate pereopods and complex and lobed gills. Myanmarorchestia peterjaegeri Hou, sp. n. closely resembles M. seabri Hou, sp. n. in gnathopod II ...

This article contains data related to the two research articles titled Transcriptomic and iTRAQ proteomic approaches reveal novel short-term hyperosmotic stress responsive proteins in the gill of the Japanese eel (Anguilla japonica) (Tse et al. [1]) and iTRAQ-based quantitative proteomic analysis reveals acute hypo-osmotic responsive proteins in the gills of the Japanese eel (Anguilla japonica)...

WHILE studying the function of the anal gills of the mosquito larva (Wigglesworth, 1932) I had occasion to observe the effects of certain electrolytes upon them, and these effects seemed sufficiently unusual to deserve separate study. Their curious character is due, no doubt, to the unusual structure of the cells in question, but it is possible that some of these observations may throw light up...

Water balance in teleosts, as proposed in the classical theories of osmoregulation originating from the work of Smith (1930), may be summarized as follows. In the marine environment net osmotic water loss from the permeable surfaces of the body, principally the gills, together with the relatively small urinary water loss, is compensated by ingestion of the external medium and the absorption of ...

Mastacembelocleidus gen. n. (Monogenoidea: Dactylogyridae) is proposed to include two species collected and redescribed from spiny eels (Mastacembelidae) in India and Iraq: Mastacembelocleidus bam (Tripathi, 1959) comb. n. (syn. Ancyrocephalus bam Tripathi, 1959) from the gills of Macrognathus pancalus (new host record) and Macrognathus aculeatus (Synbranchiformes: Mastacembelidae) from Lucknow...

The afferent pathways mediating cardiovascular and ventilatory hypoxic reflexes were identified in anaesthetized, spontaneously breathing (ASB) channel catfish, Ictalurus pimctatus (Rafinesque), by bilateral section of cranial nerve IX and branchial branches of cranial nerve X to the four gill arches (Xbi-Xb4). Cardiovascular and ventilatory responses to hypoxia and NaCN were attenuated by part...

A microscopic, ultrastructural, and morphometric study was made of the gills of tench (Tinca tinca, L.) subjected to acute experimental lead nitrate poisoning. Twenty-one adult tench were subjected to poisoning and a further 22 were used as controls. Lesions were characterized by the appearance of edema and epithelial hyperplasia and necrosis, both in cells forming part of the filtration barrie...
