“…In these studies, sperm motility is not important and efforts are made to prevent DNA damage of sperm. Therefore, this method can be used for large mammals in the intracytoplasmic sperm injection (ICSI) method, but it does not seem possible to apply it to animals with multiple eggs such as fish [178]. In the literature, there has not yet been a study in which this technology is used in fish species.…”

In this section, cryopreservation of fish genetic resources, which is one of the important applications to ensure the sustainability of genetic resources of freshwater fish species, is discussed. At the same time, information is provided about the possible sources of contamination that may be encountered during cryopreservation applications. In this context, the results of sperm, egg, and embryo cryopreservation studies of fish and their success and failure in applications were evaluated in addition to the process from past to present. Information is given about the contamination that may develop depending on the applications in the process of cryopreservation and dissolving processes, as well as the studies carried out to eliminate extracellular disease agents. In the section, in addition to the evaluation of the results of scientific studies, commercial companies that commercially carry out gamete cryopreservation applications are also included. The contamination that may develop depending on the applications in the process of cryopreservation and thawing processes, as well as the studies carried out to eliminate extracellular disease agents are mentioned.

“…The cryopreservation of fish and amphibian oocytes presents a difficult problem, because these are large cells filled with aqueous cytoplasm, typically enclosed within impermeable and tough outer coatings that inhibit, or prevent, the penetration of cryoprotectants. An alternative approach that works for fishes involves the cryopreservation and transplantation of primordial germ cells (PGCs) into sterilized surrogate recipient individuals at different life stages [ 116 , 117 , 118 , 119 ]. PGCs are the precursors of gonocytes, the stem cells that migrate to, and colonize, the genital ridges of early embryos, where they populate the testes and ovaries, and are eventually responsible for producing spermatozoa and oocytes.…”

The objective of this review is to ask whether, and how, principles in conservation biology may need to be revisited in light of new knowledge about the power of epigenetics to alter developmental pathways. Importantly, conservation breeding programmes, used widely by zoological parks and aquariums, may appear in some cases to reduce fitness by decreasing animals’ abilities to cope when confronted with the ‘wild side’ of their natural habitats. Would less comfortable captive conditions lead to the selection of individuals that, despite being adapted to life in a captive environment, be better able to thrive if relocated to a more natural environment? While threatened populations may benefit from advanced reproductive technologies, these may actually induce undesirable epigenetic changes. Thus, there may be inherent risks to the health and welfare of offspring (as is suspected in humans). Advanced breeding technologies, especially those that aim to regenerate the rarest species using stem cell reprogramming and artificial gametes, may also lead to unwanted epigenetic modifications. Current knowledge is still incomplete, and therefore ethical decisions about novel breeding methods remain controversial and difficult to resolve.

“…The quality of cryopreserved sperm may be affected by a number of factors including collection and handling procedures prior to preservation (Kommisrud et al, 2020), as well as the cryopreservation protocol being used. Cryopreservation may produce damage in cells, which affects plasma membrane, mitochondria, and chromatin structure with potential implications to fertilization success (Cabrita et al, 2010;Figueroa et al, 2016;Mayer, 2019). Until recently, published protocols for cryopreservation of salmonid milt showed relatively low and variable fertilization rates post cryopreservation.…”

Atlantic salmon are facing population declines and loss of productivity within populations due to anthropogenic impact factors and reduced survival at sea. Biobanking is an increasingly used tool to conserve the genetic integrity and diversity of populations threatened by extirpation. The aim of the current article is to discuss the opportunities and challenges that increased use of cryopreservation brings to biobanking activities, using the Norwegian Gene Bank (NGB) for Atlantic salmon as a model system. The NGB was established in 1985 and involves a traditional living gene bank, as well as "frozen gene bank"
