No-effect concentration as well as safe concentration of mercury was evaluated by exposing Perna viridis and Mugil cephalus to 24-hour static renewal bioassay for 96-hours. The 96-hour LC50 value was 75 and 129 μg/l Hg for Mugil cephalus and Perna viridis. Juvenile mullets were more sensitive than green mussel. The safe concentration calculated were 0.75 and 1.29 μg/l Hg. The no-effect concentr...

Aim of study: To describe the common behaviour flathead grey mullet (Mugil cephalus) under rearing conditions.
 Area Tepic, Mexico.
 Material and methods: Behaviours exhibited by mullets were videorecorded with submersible cameras installed inside three tanks. A total 690 min per day (07:30 - 18:30 h) recorded tank during a week. Afterwards, different behaviours juvenile M. cephalus d...

An important driver behind introductions for aquaculture of alien fish species into Pacific Island Countries and Territories (PICTs) is a lack knowledge about domestication suitability specific culture requirements indigenous taxa. Introductions may be appropriate in some circumstances, but other the associated risks outweigh benefits, so greater understanding species' potential important. This...

Dispersant use in nearshore areas is likely to increase the exposure of aquatic organisms to petroleum. To measure the toxicity of this controversial response technique, golden grey mullets (Liza aurata) were exposed to mechanically dispersed oil, chemically dispersed oil, dispersant alone in seawater, water-soluble fraction of oil and to seawater as a control treatment. Several biomarkers were...

Little is known about the prevalence and genotypes of Cryptosporidium in fish. The present study investigated the prevalence of Cryptosporidium species in cultured fingerlings (n=227), wild freshwater (n=227) and wild marine/estuarine species (n=255) of fish in Western Australia by PCR amplification at the 18S rRNA locus. Results revealed a low prevalence of Cryptosporidium infection in fish ho...

The flathead grey mullet ( Mugil cephalus ) is at the focus of an intense domestication effort. However, despite significant advances, aquaculture mullets still based on capture wild fingerlings in estuaries and stocking them into ponds. Such reliance seed limits production since it highly seasonal, unpredictable, hinders genetic improvement programs may negatively affect local fisheries. As ca...
