| In the framework of the future application of a zero-discard policy in EU fisheries, this thesis aims to develop and implement an efficient and integral waste management both on board the fishing vessels and in land (fish auctions and fish processing industry). To this end, it proposes a compaction operation able to reduce the volume and the water activity of the fish wastes, thus favouring their handling and reducing the economical costs associated to their transport and storage. To asses the viability of a waste compaction operation, the main operation factors governing the process were identified, and their influence upon the performance of the compacting operation was investigated by a statistical approach. Sardine was chosen as fish species since it... |

| Enzymatic hydrolysis of sardine viscera by three broad spectrum proteases was investigated using the pHstat method (24 h, pH 8, 50 degrees C). After hydrolysis, three fractions (sludge, aqueous phase and oily phase) were collected. For each fraction, lipids and phospholipids were quantified and molecular weights of aqueous phase peptides were determined. Under these conditions, the degree of hydrolysis (DH) varied from 1.9% (Flavourzyme), 3.1% (Protamex) and to 3.3% (Alcalase). Dry matter distribution indicated that all hydrolysis performed increased solubilisation of proteins: protein recovery for each hydrolysis ranged from 57.4% to 61.2%. Furthermore, the total lipid content in the liquid parts (oily and aqueous phases) increased (at least 85% of lipids... |

| The objective of this work was to investigate the ingestive behavior of sheep fed with different inclusions of babassu endocarp meal I. The animals receive isofibrous, isoenergetic and isonitrogenous diets containing the by-product in increasing levels of inclusion (zero; 7,5%; 15%; 22,5%). Twenty rams were used in this study and distributed in four treatments with five repetitions each. The ingestive behavior was conducted over a period of 24 hours, with visual observations at 5 minutes intervals and the variables being: idle, ruminating, feeding and chewing. The study demonstrated that the dry matter intake in function of the body weight and the metabolic weight decreased linearly as the babassu endocarp meal I was included in the diet. The feeding,... |
