Seasonal energy investment and metabolic patterns in a farmed fish.

The present research focuses on the seasonal changes in the energy content and metabolic patterns of red porgy (Pagrus pagrus) sampled in a fish farm in North Evoikos Gulf (Greece). The study was designed in an effort to evaluate the influence of seasonality in several physiological feauteres of high commercial importance that may affect feed intake and growth. We determined glycogen, lipids and proteins levels, and cellular energy allocation (CEA) as a valuable marker of exposure to stress, which integrates available energy (Ea) and energy consumption (Ec).

Breeding Substrate Containing Distillation Residues of Mediterranean Medicinal Aromatic Plants Modulates the Effects of as Fishmeal Substitute on Blood Signal Transduction and WBC Activation of Gilthead Seabream ().

This work assesses the dietary use of two insect meals of (TM) larvae reared in conventional (TM-10) or MAP-enriched substrates (MAP-TM-10) as fish meal replacements (10%) in the diets of gilthead seabream (). Fish ( = 4500; 207.19 ± 1.

Recent Developments in Seafood Packaging Technologies.

Seafood products are highly perishable, owing to their high water activity, close to neutral pH, and high content of unsaturated lipids and non-protein nitrogenous compounds. Thus, such products require immediate processing and/or packaging to retain their safety and quality. At the same time, consumers prefer fresh, minimally processed seafood products that maintain their initial quality properties.

Innovative Seafood Preservation Technologies: Recent Developments.

Fish and fishery products are among the food commodities of high commercial value, high-quality protein content, vitamins, minerals and unsaturated fatty acids, which are beneficial to health. However, seafood products are highly perishable and thus require proper processing to maintain their quality and safety. On the other hand, consumers, nowadays, demand fresh or fresh-like, minimally processed fishery products that do not alter their natural quality attributes.

Induction of gynogenesis and androgenesis in goldfish Carassius auratus (var. oranda).

Chromosome engineering was used to develop lines that expressed the stable phenotypic characteristics of goldfish, Carassius auratus (var. oranda). To obtain androgenetic individuals, carp eggs were irradiated and fertilized with sperm from goldfish bearing telescopic eyes.
