The effect of dietary black soldier fly ( Hermetia illucens ) meal on flathead grey mullet ( Mugil cephalus ) liver transcriptomic response and fillet quality was assessed. To this end, 360 juvenile flathead grey mullets (weight = 40.2 ± 0.5 g) were randomly divided into four experimental groups. Fish were fed a reference diet (BSF0) and three experimental diets in which graded levels of partially defatted black soldier fly me...

The present study investigated the macroscopical and histological features of two spontaneous seminomas developed by zebrafish adults. Two wild-type male zebrafish of AB/TU strain aged 2 and 3 years, respectively, developed gross pathological signs consisting of asymmetrical swollen abdomens. In one fish, named fish 1, the testicular alteration is referred to as one testis (the right one), while in fish 2, both testes were alt...

Parasite-mediated selection may initiate or enhance differentiation between host populations that are exposed to different parasite infections. Variation in infection among populations may result from differences in host ecology (thereby exposure to certain parasites) and/or intrinsic immunological traits. Species of cichlid fish, even when recently diverged, often differ in parasite infection, but the contributions of intrins...

Despite an increasing research conducted on ocean plastic pollution over the last decade, there are still large knowledge gaps in our current understanding of how floating plastic debris accumulating in subtropical oceanic gyres may harm the surface-associated pelagic community known as neuston. Removing floating plastic debris from the surface ocean can minimize potentially adverse effects of plastic pollution on the neuston,...
