Fish Hooks Effect Living Aquatic Resources
The fish hook is a commonly known tool used in recreational fishing, which is one of the forms of active, specialised tourism. As a component of a fishing rod, the hook is intended to be anchored into the mouth of a fish and hold the fish on the end of the line while landing it. In the context of the protection of living aquatic resources and Catch-and-Release (C&R) fishing, its role and significance are becoming broader. In addition to the impact of the hook type on fishing efficiency, including the Catch Per Unit Effort (CPUE), the importance of hook selection in terms of minimising the resulting damage to the tissues of caught and released fish is increasing.

Feed Distribution Systems for Zebrafish
Zebrafish (Danio rerio) is a well-established animal model, used in a number of research areas. In the last decade, it has also emerged as a tool to evaluate the effects of diets and dietary components and to test novel paradigms in nutrigenomics, nutrigenetics, and nutritional physiology. The standardization of the zebrafish rearing conditions, including daily nutritional and good feed management practices, is not yet achieved. Researchers focus on some recent technological solutions provided by research groups and/or biotech companies in the field of facility design, with emphasis on automated feeding distribution systems.

Melatonin in Sperm Cryopreservation of Farm Animals
Cryopreservation is a technique that offers various advantages, especially in fish, among others, that makes the reproduction of species easier through a constant supply of sperm, synchronization of the gamete availability of both sexes, storage of semen for genetic improvement programs, reduction in the cost by eliminating the need to maintain male broodstock, and conserving the gametes of endangered species. However, freezing and warming procedures for cryopreservation lead to a reduction in the quality and viability of cryopreserved sperm because of oxidative stress.

Lamiaceae as Feed Additives in Fish Aquaculture
Aquaculture products represent an important source of high-quality animal proteins, as well as essential macro- and micronutrients. The growing demand for fish, both salty and freshwater, has prompted the aquaculture industry to adopt intensive and even ultra-intensive farming systems to increase productivity. However, intensive practices are responsible for numerous problems, such as poor water quality, overcrowding, high temperature, and poor nutrition, that contribute to lowering the growth performances of fish health and immune competence, with consequently increased stress and high susceptibility to diseases. Although aquaculture plays an important role today, it is a sector that must overcome numerous challenges that hinder its expansion, such as the spreading of infectious diseases, fish health problems, and consequent economic damage.

Sustainability Potentials of Integrated Multi-Trophic Aquaculture
Integrated multi-trophic aquaculture (IMTA) systems integrate the cultivation of species from different trophic levels. Uneaten feed, solid wastes, and dissolved nutrients are turned into harvestable and healthy food, making IMTA a driver for ecologically sustainable aquaculture. Its wider sustainability potentials arise from social, environmental, and economic sustainability enhancement options.

eDNA in Fish Disease
Organisms release their nucleic acid in the environment, including the DNA and RNA, which can be used to detect their presence. Environmental DNA (eDNA)/eRNA techniques are being used in different sectors to identify organisms from soil, water, air, and ice. The advancement in technology led to easier detection of different organisms without impacting the environment or the organism itself. These methods are being employed in different areas, including surveillance, history, and conservation. eDNA and eRNA methods are being extensively used in aquaculture and fisheries settings to understand the presence of different fish species and pathogens in water.

Control and Prevention Strategies of Vibrios in Asia
It is estimated that vibriosis account for about half of the economic losses in Asian fish culture. Consequently, the prevention and control of vibriosis is one of the priority research topics in the field of Asian fish culture disease. Relevant measures have been proposed to control some Vibrios that pose a threat to Asian fish culture, there are currently only a few effective vaccines available to combat these Vibrios.

Antimicrobial Impacts of Microbial Metabolites on Fishery Products
Biopreservative bacteria, or their metabolites, compete with the undesirable microbiota and dominate the microbiota by utilizing available nutrients. Microbial metabolites (bacteriocins, reuterin, pediocin, lacticin, bacteriophage, organic acids and others) possess antimicrobial activity against a wide spectrum of spoilage and pathogenic microorganisms, including anti-listeria.

Insects for Sustainable Aquaculture
One of the greatest challenges to achieving a sustainable aquaculture is finding alternatives to fishmeal as a primary protein source in aquafeeds. Insects represent one of the most promising alternatives being explored and produced as replacements for this ingredient.

Cytokines in Carp in Response to Important Diseases
Cytokines belong to the most widely studied group of intracellular molecules involved in the function of the immune system. Their secretion is induced by various infectious stimuli. Cytokine release by host cells has been extensively used as a powerful tool for studying immune reactions in the early stages of viral and bacterial infections. Recently, research attention has shifted to the investigation of cytokine responses using mRNA expression, an essential mechanism related to pathogenic and nonpathogenic-immune stimulants in fish.
