The invention belongs to the field of aquaculture equipment engineering, and particularly relates to a double-ship continuous operation type deep sea shellfish fishing and catching system and a fishing and catching thereof. The method comprises the steps that an ecotype bottom trawl fishes and catches marine demersal shellfish into a net on the condition that the bottom environment is not influenced under the traction of a dragging ship, the collected shellfish collect in a fish bag of the ecotype bottom trawl under the action of water current and netting gears, when an online video monitoring device observes that the fish catch of the shellfish in the fish bag reaches a fishing and catching requirement, the shellfish are indrawn on a fishing and catching ship by a conveying pipeline fixed on the fish bag under the action of a self-priming pump, and a continuous fishing and catching process is completed. According to the double-ship continuous operation type deep sea shellfish fishing and catching system and the fishing and catching thereof, the shellfish catches in the ecotype bottom trawl can be conveyed to the fishing and catching ship in time, there is no need to repeat net hauling and net shooting, accordingly the operation time is saved, the leakage capture rate is reduced, the bottom environment and resources are protected, and the fishing and catching system and the fishing and catching thereof are especially suitable for the continuous fishing and catching operation of marine pasture area large-area bottom sowing shellfish.

The invention provides RNA fixed-point editing by artificially constructing an RNA editing enzyme and related application. Specifically, the invention provides a new functional protein formed by fusing an RNA recognition domain for combining RNA and an effector domain for exerting functions, and the new functional protein specifically targets target RNA through the recognition domain and performsRNA editing by using the effector domain. The RNA fixed-point editing can be used for performing gene editing at an RNA level, thereby eliminating pathogenic RNA to correct pathogenic error point mutation; or the RNA fixed-point editing can be used for editing expressed RNA molecules to perform specific control on gene functions.

The invention provides a CRISPR-Cas12j (Clustered Regularly Interspaced Short Palindromic Repeats in particular, the present invention provides a Cas effector protein, a fusion protein such a protein, and a nucleic acid molecule encoding the same. Also provided are complexes and compositions for nucleic acid editing, such as complexes and compositions for gene or genome editing, a Cas effector protein or fusion protein, or a nucleic acid molecule encoding the same. Also provided are methods for nucleic acid editing, such as gene or genome editing, using Cas effector proteins or fusion proteins.
