Summary: The study found that exposure of flatfish early life stages to ultraviolet radiation led to adverse effects such as decreased growth, impaired behavior, and inhibition of neurotransmitters and biotransformation. In the metamorphosis stage, the main observed effect was a decrease in growth. This suggests that UV exposure may have implications in later life stages.

Summary: Infectious diseases are a major cause of social and economic losses in world aquaculture, with bacterial diseases such as photobacteriosis impacting the production of Senegalese sole. This study aimed to develop an oral DNA nanovaccine for S. senegalensis juveniles against Photobacterium damselae subsp. piscicida (Phdp). The results indicate that oral vaccination with CS-TPP+pPDPimpdh NPs may be acting through non-specific immune responses as well as specific humoral and cell mediated immunity, providing a promising step towards developing an oral DNA nanovaccine against Phdp in sole.

Summary: This study investigated the effects of ultraviolet radiation (UV) and triclosan (TCS) on the metamorphosis of Solea senegalensis, and found that TCS induced malformations, accelerated and delayed metamorphosis, while UV radiation enhanced these effects. The expression of thyroid axis-related genes were down-regulated after TCS exposure and remained down-regulated even after a period in clean media. These stressors may have implications for the ecological performance of the species.

Summary: The study investigated the sublethal effects of pesticides alone and in combination with microplastics (MPs) on enzymatic activity in Solea senegalensis. The results showed that cholinesterase activity in the tissues of S. senegalensis was inhibited by the insecticide chlorpyrifos (CPF) and the antibacterial triclosan (TCS). Furthermore, the presence of MPs was found to enhance the effects of CPF on cholinesterase activity. These findings highlight the importance of assessing the combined effects of pesticides and microplastics due to their abundance in the marine environment.

Summary: The study found that COX-2 is functionally active during chick embryogenesis, impacting the structural configuration of multiple organs and tissues primarily through regulation of PGE(2) levels. Inhibition of COX-2 resulted in significant developmental anomalies, while compensatory increase in COX-1 activity helped maintain levels of other effector prostanoids. Among the three prostanoids studied, PGE(2) appeared to be predominantly regulated by activated COX-2 in this process.

Summary: This study investigated the effects of treatments with homologous recombinant follicle-stimulating and luteinizing hormones on sperm production in sole. The results showed that these treatment increased gonad weight, stimulated spermatogenesis, and enlarged the size of the seminiferous and efferent ducts. Sperm production peaked at 48 hours after luteinizing hormone treatment, and low doses of follicle-stimulating hormone were highly efficient in stimulating sperm production when luteinizing hormone was administered at a temperature close to that occurring during maximum natural spermiation.

Summary: Wild adult females of the flathead grey mullet captured in the western Mediterranean were studied to analyze the lipid and fatty acid composition in different tissues during the reproductive cycle. The results showed that muscle did not store lipids for gonadal growth, while liver had higher lipid content and exhibited dynamic changes during gonad development. The total lipid content in the ovary increased with maturation and decreased after spawning. Peritoneal fat was a transitional fat and its function varied. The accumulation of lipids in the ovary was likely from the diet.

Summary: This study aimed to describe the common behavior of grey mullet under rearing conditions. It found that grey mullet is a species with constant locomotion associated with feeding and showed reduced movement during dark periods. The study also observed that grey mullet is a non-aggressive fish species and has a high predisposition for adaptation to captivity. The behavioral frequencies of grey mullet juveniles were similar among the different tanks, except for bottom feeding. These findings are important for optimizing rearing techniques and welfare in the aquaculture industry.
