Learning objectives

Referring to knowledge

• Know the advances in energy, nutrition, digestion and metabolism in aquaculture species.
• Choose the right nutrition parameters to obtain a quality product.
• Know the reproductive strategies of aquatic animals in culture and their endocrine regulation, and the effect of environmental conditions on reproduction.
• Have the tools to manipulate reproductive processes and their application in aquaculture.
• Understand the development and growth of fish species of interest in aquaculture and their endocrine regulation, as well as the main events in embryonic and larval growth.
• Identify parameters of muscle growth and meat quality, and be able to develop the technological aspects of growth.

Teaching blocks

1. Food and nutrition

* Requirements. Metabolic rate. Energy balance and components. Gastrointestinal tract: anatomy and physiology. Digestion and assimilation. Protein metabolism: protein synthesis and degradation, energy cost of protein synthesis. Protein replacement determination: function of free amino acids. Carbohydrate and lipid metabolism: dietary protein saving effect. Essential fatty acids. Antioxidants and oxidative stress. Endocrine regulation of metabolism. Control of intake, digestion and assimilation. Manufacture of compound feed in fish farming: raw materials, macronutrients and micronutrients, basis of the formulation

2. Reproduction

* Reproductive strategies. The gonads: structure and function. Gametogenesis: oogenesis and spermatogenesis. Environmental effects on reproduction. Endocrine regulation of reproduction: hypothalamic, pituitary and gonadal hormones. Hormonal and chromosomal manipulation of reproduction in aquaculture: spawning induction, sex control and sterility induction techniques. Gamete quality: techniques for determining quality and cryopreservation processes

3. Growth

* Growth stages in fish. Embryonic development and larval development in teleost fish: hatching, organogenesis and physiology of the different organic systems. Digestive system of larvae: endogenous and exogenous nutrition. Skeletal deformities and pigment problems. Effects of environmental parameters on growth. Metamorphosis. Muscle growth. Characteristics and markers of fiber types. Endocrine regulation: growth factors, thyroid hormones and other endocrine factors. Quality of fish meat. Reference parameters. Meat quality markers. Types and production systems in marine aquaculture
