Risks and Uncertainties [Abstract]
Risks and Uncertainties	3. Risks and uncertainties The Company is subject to risks and uncertainties common in the biotechnology and aquaculture industries. Such risks and uncertainties include, but are not limited to: (i) results from current and planned product development studies and trials; (ii) decisions made by the FDA or similar regulatory bodies in other countries with respect to approval and commercial sale of any of the Company’s proposed products; (iii) the commercial acceptance of any products approved for sale and the Company’s ability to produce, distribute, and sell for a profit any products approved for sale; (iv) the Company’s ability to obtain the necessary patents and proprietary rights to effectively protect its technologies; and (v) the outcome of any collaborations or alliances entered into by the Company. COVID-19 Although the COVID-19 pandemic has diminished in the United States and other parts of the world as vaccines have become more readily available, several variants of the virus continue to spread. Local governmental authorities in the United States and Canada have issued, and continue to update, directives aimed at minimizing the spread of the virus and the Company continues to monitor its status. The ultimate impact of the evolving COVID-19 pandemic on the Company’s operations will depend on future developments, which cannot be predicted with confidence, and the Company cannot predict the extent or impact of the extended period of continued business interruption and reduced operations caused by the COVID-19 pandemic or any additional preventative or protective measures taken in response. In connection with the COVID-19 pandemic, management continues to make modifications to biosecurity procedures and employee welfare practices at the Company’s farm sites to adapt to local requirements and to provide a safe work environment. Concentration of credit risk Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents, and marketable securities. This risk is mitigated by the Company’s policy of maintaining all balances with highly rated financial institutions, investing cash equivalents with maturities of less than 90 days, and investing marketable securities with maturities of less than 180 days. The Company’s cash balances may at times exceed insurance limitations. The Company holds cash balances in bank accounts located in Canada to fund its local operations. These amounts are subject to foreign currency exchange risk, which is minimized by the Company’s policy to limit the balances held in these accounts. Balances in Canadian bank accounts totaled $147 thousand and $224 thousand at March 31, 2022 and December 31, 2021, respectively. The Company also holds cash equivalent investments in a highly liquid investment account at a major financial institution. As of March 31, 2022 and December 31, 2021 the cash equivalent investment balance was $56.7 million and $73.3 million, respectively.
