A laboratory experiment was conducted to determine hexavalent chromium (Cr) accumulation in the mullet and investigate Cr toxicity using a panel of biomarkers including metallothioneins (MTs), glutathione (GSH), glutathione S-transferase (GST), and superoxide dismutases (SODs) for 4 weeks. Cr bioaccumulation in all tissues, except muscle, was consistently timeand dose-dependent. The accumulatio...

Se evaluó los microplasticos (MP) presentes en cinco peces de importancia económica el Perú: Sciaena deliciosa (Tschudi, 1846) (Sciaenidae) “lorna”, Isacia conceptionis (Cuvier, 1830) (Haemulidae) “cabinza”, Scartichthys gigas (Steindachner, 1876) (Blenniidae) “borrachito”, Mugil cephalus (Linnaeus, 1758) (Mugilidae) “lisa” y Scomber japonicus (Houttuyn, 1782) (Scombridae) “caballa”.

This experiment was conducted to evaluate the efficacy of different levels of Echinacea (Echinacea purpurea) methanol extract on the growth performances (final weight (FW), daily growth ratio (DGR), feed conversion rate (FCR), voluntary feed intake (VFI) and protein efficiency ratio (PER) and some of hematological parameters (hemoglobin (Hb), hematocrit (Hct), red blood cell (RBC) and white blo...

The grey mullet is a catadromous species that spawns in the taurine-rich seawater environment, followed by young fish generally migrating to less saline, low taurine waters during larva-juvenile transition. Consequently, this study aimed (1) determines whether there dietary requirement juvenile for enhanced growth and (2) potential biosynthesis. experimental system consisted of sixteen 400-l V-...

Beside that the fish species and their sub-populations are highly important as a keystone in coastal marine ecosystem, there very few studies on presence, distribution temporal variations within around lagoon ecosystems Albania. This paper provides an updated review life cycle, fishery, exploitation state management of main subject commercial fishing Karavasta lagoon, southeastern Adriatic coas...

Abstract Wadi El Natrun is an elongated narrow depression in the Western Desert of Egypt. The characterized by many ancient alkaline salt lakes. These lakes are filled with water winter and dried up summer. Recently, some become permanently dried, while others submerged throughout year as Bieda Lake. Lake has undergone ecological changes due to prolonged extraction minerals continual dischargin...
