The Application of Potassium Diformate in Aquaculture
Potassium diformate (KDF) is an organic acid salt. It is a dimer formed through hydrogen bonding between one molecule of formic acid and one molecule of potassium formate. The chemical formula of KDF is HCOOH·HCOOK, with a molecular weight of 130.14. It is a white or slightly yellow crystalline powder with no discernible pungent odor. KDF dissolves in water and exhibits a pronounced hygroscopic nature. Its aqueous solution is acidic and remains stable under acidic conditions, while it decomposes into formate and formic acid under neutral or slightly alkaline conditions. Compared with formic acid, KDF overcomes the irritability, corrosiveness, and instability of formic acid. Therefore, KDF is a more suitable additive in feed, providing a safer and more stable solution in maintaining the balance of microbial communities in aquatic animals.

Salmonids' Immune Response to Myxozoan Parasite Myxobolus cerebralis
Salmonids are affected by the economically significant whirling disease (WD) caused by the myxozoan parasite Myxobolus cerebralis. In the past, it was endemic to Eurasia, but it has now spread to different regions of North America, Europe, New Zealand, and South Africa. Among salmonids, rainbow trout is considered the most highly susceptible host. Upon entering to the host’s body, the parasite invades the spine and cranium, resulting in whirling behaviour, a blackened tail, and destruction of cartilage. The disease is characterized by the infiltration of numerous inflammatory cells, primarily lymphocytes and macrophages, with the onset of fibrous tissue infiltration.

Dietary Microalgae on Fish Health and Fillet Quality
An increase in the consumption of food fish, combined with a decrease in the harvest of fish, is driving the aquaculture industry at a fast pace. In parallel with the growth in the aquaculture sector and resulting stresses, the prevalence of diseases in farmed fish can increase.

Imaging Techniques Used in Fish Bioimages
Detecting skeletal or bone-related deformities in model and aquaculture fish is vital for numerous biomedical studies. In biomedical research, model fish with bone-related disorders are potential indicators of various chemically induced toxins in their environment or poor dietary conditions. In aquaculture, skeletal deformities are affecting fish health, and economic losses are incurred by fish farmers.

Enhanced Digestibility and Nutrient Utilization with Chitinase
The aquaculture industry is looking for sustainable alternatives to conventional fish meals in fish feed, and insect-based meals are proving to be a promising solution. These meals are nutritionally optimal as they have a high protein content and an ideal amino acid profile. However, the presence of chitin, a component of the insect exoskeleton in these meals presents both an opportunity and a challenge. Chitosan, a derivative of chitin, is known to improve the physiological functions of fish, including growth, immunity, and disease resistance. While chitin and its derivative chitosan offer several physiological benefits, their presence can affect the digestibility of feed in some fish species, making the inclusion of insect-based meals in aquafeeds complex. Chitinase, an enzyme that breaks down chitin, is being investigated as a potential solution to improve the nutritional value of insect meals in aquafeed.

The Role of Seaweed in Aquaculture Production
Seaweed, also known as macroalgae, represents a vast resource that can be categorized into three taxonomic groups: Rhodophyta (red), Chlorophyta (green), and Phaeophyceae (brown). They are a good source of essential nutrients such as proteins, minerals, vitamins, and omega-3 fatty acids. Seaweed also contains a wide range of functional metabolites, including polyphenols, polysaccharides, and pigments. The nutritional and functional properties of seaweed attest to their potential to be incorporated into aquafeed to safeguard fish growth and health as the global demand for fish and seafood products rapidly increases.

Aquaculture Development in Nigeria
Aquaculture or fish cultivation offers a major source of animal protein and contributes heavily to household diets, livelihood, and economic development in many countries and regions of the world. Nigeria is not left out. In the agricultural sector of the Nigerian economy, aquaculture has been recorded as having the fastest growth rate.

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.

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.

Atlantic Bluefin Tuna Farming in the Mediterranean
Atlantic bluefin tuna (Thunnus thynnus) is the most important tuna species in Mediterranean tuna fishery and a valuable commodity on the global fish market. Croatia is a pioneer in tuna farming in the Mediterranean and the only country that has the exclusive right to farm wild-caught juvenile tuna (8 to 30 kg).
