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.

Management of Pike in Alaska
Northern pike are an invasive species in southcentral Alaska and have caused the decline and extirpation of salmonids and other native fish populations across the region. Northern pike control actions are tailored to the unique conditions of waters prioritized for their management, and all efforts support the goal of preventing further spread of this invasive aquatic apex predator to vulnerable waters.

Major Challenges for Seafood Packaging
Seafood is a highly economical product worldwide. Primary modes of deterioration include autolysis, oxidation of protein and lipids, formation of biogenic amines and melanosis, and microbial deterioration. These post-harvest losses can be properly handled if the appropriate packaging technology has been applied. Therefore, it is necessary for packaging deterioration relevance to be clearly understood.

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.

Kazakhstan’s Fisheries Sector
Kazakhstan, a former Soviet republic that is now independent, lies near the center of arid Eurasia. Its sparse hydrographic network includes a small number of large rivers, lakes, and reservoirs, many ponds and smaller streams, as well as littoral zones bordering the Caspian Sea and the Aral Sea. A diverse fisheries sector, initially based on wild fish capture and later including aquaculture, developed in these waters during the Soviet era, when animal agriculture was unable to meet the protein needs of Soviet citizens. The sector, which was originally centered on the Volga–Caspian basin, was tightly managed by Moscow and benefitted from coordinated investments in research, infrastructure, and human resources, as well as policies to increase the consumption of fish products. Independence in 1991 administered a political and economic shock that disrupted these relationships.

Invasion of African Clarias gariepinus in Bangladesh
The African catfish Clarias gariepinus has been introduced for aquaculture in Bangladesh due to the scarcity of indigenous C. batrachus fingerlings. The African catfish Clarias gariepinus is a highly carnivorous species and predates small indigenous freshwater fishes when escaping into natural water bodies. However, the government of Bangladesh has banned the farming of C. gariepinus due to the carnivorous nature of this species. The introduction of C. gariepinus caused native biodiversity loss due to its predatory nature.

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.
