Indicator stem cell line/transgenic (non-human) living organism for non-destructive, self-signalizing visualization of nuclear structures, which allows the identification of nuclear and chromosome anomaliesincluding micronucleias consequence of exposure to genotoxic compounds, wherein the stem cell line is a transgenic stem cell line from a (non-human) animal with nuclei labelled with a fluorescent protein fused to a chromatin-associated protein and/or the living organism is a transgenic (non-human) living organism in which a cell lineage has nuclei labelled with a fluorescent protein fused to a chromatin-associated protein.

Methods for the production of reproductively sterile fish and aquatic animals for aquaculture, the aquarium trade, and control of invasive species are described. The methods include disruption of gonadal development through the administration of compounds that lead to the failure of fertile gonadal development. Compounds may be delivered to the eggs prior to fertilization or water activation or post fertilization and water activation by contacting unfertilized or pre-water-activated fertilized eggs or fertilized eggs in an immersion medium including the compound of interest. Compounds may be conjugated with a molecular transporter compound effective for chorionic transport of the conjugate. The compounds may be antisense Morpholino oligomers that are capable of effectively suppressing the expression of the dead end gene or other essential genes for germ cell development in fish and other egg-producing aquatic animals.

The disclosure provides, among other things, compositions and methods useful for maintaining splicing fidelity in a cell. The compositions can include a compound that modulates the expression level or activity of one or more components of the spliceosome complex in a cell. In some embodiments, the compound is useful for restoring the expression level or activity of one or more splicing complex components to the expression level or activity present in the cell at an earlier chronological age. In some embodiments, the compound is useful for modulating the expression level or activity of one or more splicing complex components in the cell to the expression level or activity present in the cell under caloric restriction.

The present disclosure relates to an automated method, computer program, and system for estimating the average fish weight in an aquaculture environment. An underwater camera in the aquaculture environment captures video frames from the environment. These frames are inputted into a machine learning detection model that has been trained to detect fish. The machine-learning vision detection model identifies a virtual box-region around detected fish and outputs size and location for the virtual-box regions, as well pixel data related to the virtual-box region and the frame as a whole. This size, location, and pixel data is processed and then inputted into an AI-based length estimation model, which computes a fish length for each virtual-box region inputted into the model. The system then calculates the average fish weight from the fish length using an analytical model.

The present invention relates to transgenic ornamental fish, as well as methods of making such fish by in vitro fertilization techniques. Also disclosed are methods of establishing a population of such transgenic fish and methods of providing them to the ornamental fish industry for the purpose of marketing.

The present invention provides compositions and methods for light-activated cation channel proteins and their uses within cell membranes and subcellular regions. The invention provides for proteins, nucleic acids, vectors and methods for genetically targeted expression of light-activated cation channels to specific cells or defined cell populations. In particular the invention provides millisecond-timescale temporal control of cation channels using moderate light intensities in cells, cell lines, transgenic animals, and humans. The invention provides for optically generating electrical spikes in nerve cells and other excitable cells useful for driving neuronal networks, drug screening, and therapy.

The present invention provides Maternal Sterility Constructs (MSC) and methods of producing sterile progeny lacking germ cells. Female fish carrying the MSC transgene will give rise to a sterile generation, as the MSC specifically eliminates Progenitor Germ Cells (PGCs) of her progeny. These females are called lineage ending females. Male fish carrying the MSC transgene, however, give rise to fertile progeny (assuming the male is not derived from an MSC-transgenic female). Thus, MSC transgenic males can be used to propagate the transgenic line. The invention can be advantageously applied to provide effective population control and improve culture performance of farmed species, such as fish.

The present invention includes nucleic acid hybrid molecules capable of entering cells comprising at least one vivo-morpholino oligonucleotide (vivo-MO) comprising a guanidine-rich head conjugated to the 5 end, and at least one standard oligonucleotide comprising a gene-specific sequence and a standard oligonucleotide pairing sequence, wherein the standard oligonucleotide is bound to the vivo-morpholino oligonucleotide through base pairing to form a hybrid and wherein the vivo-morpholino oligonucleotide pairing sequence is complementary to the standard oligonucleotide pairing sequence.

The subject invention provides microbe-based products, as well as their use, for enhancing aquaculture. In particular, the subject invention provides materials and methods for producing healthy and high quality farmed fish by applying yeast and/or bio surfactant-based compositions to a fish farm. In one embodiment, the subject invention improves the environment in which the fish are farmed. In another embodiment, the subject invention provides a highly nutritious fish feed, as well as methods of feeding fish at low cost.

The present invention relates to transgenic ornamental fish, as well as methods of making such fish by germ cell transplantation techniques. Also disclosed are methods of establishing a population of such transgenic fish and methods of providing them to the ornamental fish industry for the purpose of marketing.
