Influence of Fish Handling Practices Onboard Purse Seiners on Quality Parameters of Sardines () during Cold Storage.

Small pelagic fish are a rich source of high-quality proteins and omega-3 fatty acids, but they are highly perishable due to the activity of microorganisms, endogenous enzymes, and oxidation processes that affect their muscle tissues during storage. This study focused on analyzing the influence of fish handling practices onboard vessels on sensory quality attributes, pH, water holding capacity, TVB-N, proteolytic changes, and lipid oxidation in sardine muscle tissue during cold storage. Experiments were conducted onboard fishing vessels during regular work hours, with added consistency, accounting for similar sardine sizes (physiological and reproductive stages) under similar environmental conditions.

Supplementation with imuno-2865® in gilthead sea bream (Sparus aurata Linnaeus, 1758): Effects on hematological and antioxidant parameters.

The aim of this study was to evaluate the effects of IMUNO-2865(®) on hematological and antioxidative parameters in sea bream. Total of 640 sea bream were fed with diets containing 0 (Group 1), 1 (Group 2), 10 (Group 3) and 25 (Group 4) g of IMUNO-2865(®) kg(-1) feed during 90 days. Samples were taken each month and three months after the supplementation.
