Artificial intelligence (AI) is gaining widespread use in the preparation and publication of manuscripts. The technology enables the automation of time-consuming tasks including literature searches and review, and the management of largescale data sets. However, there is concern about the role of AI in the construction/writing of manuscripts, an...

Production of microalgae for biodiesel, one of the alternative renewable energy sources, is costly due to nutrient media. Industrial and domestic wastewater contains nitrogen, phosphorus and other nutrients that are the primary food source for algae. Releasing this environmentally harmful effluent into receiving bodies of water, such as the sea or...

Rotifers are microscopic aquatic animals found in different aquatic environments. These creatures are small and they have rapid reproduction. In aquaculture, rotifers are used as live feed for fish and larval fish diets. They are fast growing and rich in essential nutrients such as lipids, vitamins for using aquaculture diets. Similarly rotifers im...

Since its inception ~6000 years ago, aquaculture has evolved to enable its survival and growth to become a major contributor of protein of high nutritional value for human consumption, thereby improving food security and reducing poverty. Best practices have been established and updated to reflect developments as they occurred. Currently, best prac...

The rainbow trout is an intensively cultured species because of its more cultivatable character than the brown trout. In this experiment, the brown trout culture did not expand due to low growth performance compared to that of the rainbow trout. This experiment was conducted in a commercial trout farm, Aegean Area (Turkey). Growth performances and...

Flavour of meat or sea products is generally thought to consist of the volatile components sensed in the nose, both through the nostrils and from inside the mouth. Taste results from the combination of basic flavors (sweet, sour, bitter, salt and umami). The flavors and aromas associated with meat and sea foods are generally those that develop duri...
