Colonization of the lagoon at Moorea Island, French Polynesia, by fish larvae was studied with a net fixed on the outer reef crest in order to observe die1 and lunar cycles. Fish larvae entered the lagoon at dusk and at night, mainly during moonless periods. Colonization was closely related to decreasing light intensity; it was 4 times greater during new moon than during full moon. Other enviro...

AIMS To identify the causative agent of the mortality in the fish, Mugil cephalus, in Muttukadu lagoon. METHODS AND RESULTS An enteric bacterium from the kidneys of moribund fish M. cephalus, was isolated and identified as Enterobacter cloacae (MK). Mugil cephalus was experimentally infected by this isolate and was re-isolated from the kidneys of the moribund fish. Enterobacter cloacae isolat...

as a part of a major ecological study of hanna wetland, semirum region, isfahan province, parasitic infestation of 3 native and one introduced fish species were investigated. a total of 120 fish specimens were collected by both cast net and a series of gillnets between fall and winter 2007, and spring and summer 2008. some of the observed parasites are reported for the first time as new host re...

We studied the spatial variability and within-year temporal changes in hydrological features, grain size composition and chemical characteristics of sediments, as well as macrofaunal assemblages, along a heavily modified inlet in the Gulf of Oristano (western Sardinia, Italy). The inlet connects the Cabras lagoon to the gulf through a series of convoluted creeks and man-made structures, includi...

Parasitic diseases are harmful and limiting factors in breeding and rearing ornamental fish industry. In this study, 400 apparently healthy ornamental fishes from five species (each species 80 specimens) including: Goldfish (Carassius auratus), guppy (Poecilia reticulate), angelfish (Pterophyllum scalare), discus (Symphsodon discus) and sailfin molli...

Aspects of the biology of Mormyrus rume (Cuvier and Valenciennes) in Lekki lagoon were investigated. This included the length-weight relationship, condition factor, food and feeding habits and the fecundity of the fish species. The major fishing methods employed for collecting the 225 specimens were castnetting and setnetting. The total lengths ranged from 15.0 to 24.9 cm while the standard len...

  Two hundred forty seven species of parasites from Iranian freshwater fishes are presented in this synopsis. The parasites were recorded from infestations in fish from different parts of the country and summarized according to host species, organs were the parasite infestations occurred, province, faunal region and reference numbers. The following aspects of parasite infestations were also dis...
