The black soldier fly (BSF, Hermetia illucens) is a prominent insect species and novel alternative ingredient for aquafeeds. This study aimed to evaluate the replacement of commercial feed with fresh whole larvae (BSFL) Colossoma macropomum. Juvenile tambaqui (115.2 ± 0.9 g/fish) were stocked in 800 L tanks (11 fish/tank) operating as recirculating system. dietary treatments consisted only (BSF...

In this study the distribution and accumulation indices of some heavy metals in sediments and Tilapia zillii fish in freshwater catchment of River Niger by Ajaokuta Steel Company (ASC), North Central Nigeria were investigated. Water, bottom sediments and Tilapia zillii fish samples were collected upstream and downstream of the drainage column by ASC, Ajaokuta. The sample were digested according...

The effect of aqueous solution of citric acid (CA) on the lipid stability of the European catfish (Silurus glanis) fillets during frozen storage (up to 6 months) was investigated. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides and TBA) and complemented by the measurement of expressible moisture and sensory evaluation (flesh odor, consistency and f...

this study was conducted to determine the residues of mercury (hg), lead (pb), copper (cu) and cadmium (cd) in the imported tilapia fillets. thirty random samples from imported tilapia fillets were collected from different markets in isfahan city, central iran. they were analyzed using graphite furnace atomic absorption spectrometer (perkin elmer 800) for pb, cu, cd and flow injection mercury s...

The effects of the use of essential oil of Rosmarinus officinalis on the chemical quality and fatty acids of fish fillets of Ctenopharyngodon idella were investigated during frozen storage at -18 ºC for 6 months. Fish fillets were divided into three groups the control (C) without rosemary essential, the second group with 0.2 % rosemary essential oil (A) and the third with 0.4 % rosemary essenti...

Trials were conducted to determine effects of AQUI-STM sedation during harvest (rested-harvest) on physiological responses and fillet quality of channel catfish, Ictalurus punctatus. Rested-harvest is defined as application of an anesthetic immediately before harvest to reduce fish activity associated with a normal harvest. Doses of 25–35 ppm AQUI-STM were effective for rested-harvest of catfis...

Mercury Levels Lower in Great Lakes, but Still High Although mercury concentrations have decreased about 20% in fish, fish-eating birds, and inland lake sediments across the Great Lakes region in recent decades, levels in top predator fish and wildlife are still dangerously high, and in some places concentrations in some fish and wildlife may now be increasing, according to a new report. Levels...

Diphyllobothriasis, a parasitosis caused by the flatworm Diphyllobothrium latum, is contracted by consuming raw or undercooked freshwater fish. The aim of this study was to evaluate the situation of this parasitosis during the past 20 years in Europe through the analysis of databases and search engines (Medline, Cabi Helminthological abstracts,Yahoo, Google), and through a questionnaire sent to...
