introduction: fish mycobacteriosis is caused by the non-tuberculous mycobacteria. infected fish are normally the primary source of infection, although non-tuberculous mycobacteria can be found in the environment. the present study was designed to  investigate the few recently found suspected cases of mycobacteriosis in iranian ornamental fish tanks.   materials and methods: pathological specime...

The infection status of fishborne zoonotic trematode (FZT) metacercariae was investigated in fishes from 2 localities of Lao PDR. Total 157 freshwater fishes (17 species) were collected in local markets of Vientiane Municipality and Champasak Province in December 2010 and July 2011, and each fish was examined by the artificial digestion method. Total 6 species of FZT metacercariae, i.e., Opisth...

Species richness, abundance and biomass of fishes from seagrass and unvegetated habitats were analysed for sites in the Swan Bay region of Port Phillip Bay, and Corner Inlet, Victoria, Australia. Fish assemblages from intertidal Zostera muelleri sites showed greater similarity with a number of shallower unvegetated sites than to subtidal Heterozostera tasmanica. Similarly, subtidal, unvegetated...

The infection status of freshwater fish with digenetic trematode metacercariae was examined in water systems of Hantangang and Imjingang (River), the Republic of Korea. A total of 877 (594 from Hantangang and 283 from Imjingang) fishes were examined by the artificial digestion methods. Clonorchis sinensis metacercariae were detected in 7 (1.2%) fishes (in 3 spp.) from Hantangang in Cheorwon-gun...

The Genome 10K project aims to sequence the genomes of 10,000 vertebrates, representing approximately one genome for each vertebrate genus. Since fishes (cartilaginous fishes, ray-finned fishes and lobe-finned fishes) represent more than 50% of extant vertebrates, it is planned to target 4,000 fish genomes. At present, nearly 60 fish genomes are being sequenced at various public funded labs, an...

Fishes are delicious. At least herons, kingfishers, mergansers, and all marine birds seem to think so. Marine mammals seem to think so. Minks and bears seem to think so. The big fishes themselves concur. As a taxonomic group, fishes face one of the most diverse arrays of predators imaginable. Threat comes from below and from above, during the day and at night, and at almost all stages of life. ...

The world's oceans are home to many fantastic creatures, including about 16,000 species of actinopterygian, or ray-finned, fishes. Notably, 85% of marine fish species come from a single actinopterygian subgroup, the acanthomorph or spiny-rayed fishes. Here, we review eight functional innovations found in marine acanthomorphs that have been instrumental in the adaptive radiation of this group in...

Stephen Paul Cotterell FISH LANDINGS, DISCARDS AND BENTHIC MATERIAL FROM DEMERSAL TRAWLING IN THE WESTERN ENGLISH CHANNEL (ICES VIle) This study examined the impact of inshore single boat otter trawling from Newlyn, Looe, Plymouth and Salcombe and pair boat demersal trawling from Looe and Plymouth on the benthic environment off the SW peninsula of the UK between 1998 and 2000. Fish and shellfis...

a systematic parasitological examination was carried out on 266 freshwater fish speci-mens, belonging to 11 species, from northwest of iran during the period from summer 2001 to summer 2002. twelve parasite species including diplostomum spathaceum, al-locreadium isoporum, ligula intestinalis, digrama sp., caryophylleus laticeps, rhabdocona hellichi, eustrongylides excisus, argulus foliaceus, la...

Coastal salt marshes provide important habitat for fishes and crustaceans, including species of commercial value that feed or take refuge in the marsh. Yet population abundances vary considerably between sites, often without clear explanation. We hypothesised faunal abundance mean size would be positively related to 2 physical properties govern marsh accessibility water-dependent species, as ha...
