Total dissolved gas (TDG) is suggested to be one possible explanation for the extensive mortality of endemic fish suffered from bubble disease (GBD). We investigated effects water depth on adult Schitzothorax prenanti susceptibility GBD in TDG supersaturated 11.5 km downstream Dagangshan dam a two-year (2016–2017) live cage study. The probability survival significantly increased at greater dept...

Fisheries sector plays a significant role in national food security, empowerment and foreign exchange earnings the economy of Bangladesh. At same time, Bangladesh is blessed with enormous water resources inland culture (8,21,923 ha), capture (38,90,282 ha) marine (1,18,81,300 having great potentials fisheries production. Inland culture, provides 56.76%, 28.19% 15.05% production, respectively. T...

An HPLC analytical method based on a methanol extraction, C clean-up, derivatization using 8 trifluoroacetic acid anhydride and reverse-phase HPLC was developed for the detection of 22,23-dihydroavermectin B in marine sediment. The limit of quantitation was determined as 1a Ž . 0.93 ng 22,23-dihydroavermectin B H B per g of sediment. This method was used to 1a 2 1a determine the concentrations ...

This study examined the growth response of yellowfin seabream, Acanthopagrus arabicus, reared in floating net cage fed at variable daily feeding frequencies. Thirty healthy fish (49.7±0.3 g initial weight) were stocked in each of the 12 net cages (1.5×1.5×1.5m). Three cages in each group were assigned to four different feeding frequency i.e., two, three, four and six times/day designated as FF1...

This document addresses the potential impacts of climatic change on the aquaculture sector and to a lesser extent the contribution of aquaculture to climate change. In order to achieve these objectives, the status of this subsector in relation to the total food fish supply, recent changes therein and other related aspects are analysed with a view to addressing potential adaptations and mitigati...

Trout fishing means raising fish in water whose temperature does not exceed +18°C under completely or partially artificial conditions. Today, several belonging to the salmon family are bred cold fisheries world. These river trout (Rainbow - Oncorhynchus mykiss ), brook (Brown Salmo trutta and brown (Brook Salvelinus fontinalis ). Currently, breeding dominates global production. Its cultivation ...

Helicobacter pylori remains one of the most common bacterial infections worldwide. Clarithromycin resistance is the most important cause of H. pylori eradication failures. Effective antibiotic therapies in H. pylori infection must be rapidly adapted to local resistance patterns. We investigated the prevalence of clarithromycin resistance due to mutations in positions 2142 and 2143 of 23SrRNA ge...

The present study was conducted to examine the impact of cage aquaculture on benthic communities in coastal areas (depth 25 to 50 m) from fish farming operations located along the southeastern Black Sea (Ordu-Perşembe, Trabzon-Yomra and Rize central). Sampling was conducted seasonally from April 2007 to 2009. Sediment samples were taken using Ekman Grab (box core- 0.04 m2). Temperature, salinit...

Two cultured marine fish, the Japanese seabass (Lateolabrax japonicus) and red seabream (Pagrus major) were collected from eight fish cage sites along the coast of Fujian province in China. The concentrations of Ag, As, Cd, Co, Cu, Fe, Mn, Se, and Zn in their muscle, stomach and liver tissue were quantified. The risk of these trace elements to humans through fish consumption was then assessed. ...

Salmonid farming affects both the environment and other industries, with impacts of wild fish attracted to fish farms being a major concern. Here, we summarized existing knowledge on the impacts of such aggregations around open-cage salmonid farms in Norway on the environment and human activities and on the interactions of these impacts. Waste fish feed is considered the major cause for the att...
