The preservation of marine ecosystems and the safety harvested seafood have elicited global concern. In this study, we evaluated bacterial contamination levels in sea urchin Paracentrotus lividus gonads with relation to environmental factors physicochemical parameters seawater. This investigation aimed assess Total Aerobic Mesophilic Bacteria (TAMB), Enterobacteriaceae (ETB), Fecal Coliforms (FC), Staphylococcus aureus (STAPH), Escherichia coli (E. coli), Salmonella spp. (SALM) collected from Tangier coast between December 2020 November 2021, per Moroccan regulations (NM 08.7.040). Twenty-one physicochemical, environmental, biological were assessed 360 samples P. four seasons. results these processed using multivariate statistical approaches. It was found that almost all had concentrations below regulatory limits, except for FC July (173 CFU/g). Furthermore, E. SALM absent. Principal component analysis (PCA) demonstrated F1 associated a combination microbiological, anthropogenic factors. These associations contributed 59.02% data variations strongly influenced by seasonality. F2 26.33% variations. findings may aid decision-makers protection public health sensitive locations such as northern Morocco.

Understanding and controlling reproductive cycles gonadal maturation in cultivated species are crucial aquaculture. The sea urchin Paracentrotus lividus, known for its edible gonads, requires careful control both reproduction commercialization. This study explores the impact of temperature, photoperiod, diet on development to enhance year-round aquaculture practices. Using two independent cultivation systems, we manipulated environmental conditions mimic different seasons. Sea urchins were exposed natural or temperature photoperiod fed either (Ulva spp.) formulated diets. gonadosomatic index (GI) histological analysis assessed development. Results revealed a clear correlation between conditions, diet, maturation. Manipulated accelerated maturation, with showing advanced stages compared conditions. Furthermore, diets exhibited higher GI values, indicating enhanced Histological confirmed particularly females. underscores feasibility through manipulation enabling marketable gonad production. Providing rich polyunsaturated fatty acids, notably docosahexaenoic acid (DHA), enhances commercial value. These findings optimize practices P. highlighting adaptability yield-maximizing production strategies.
