An apparatus for reducing by-catch of seabirds or turtles during fishing include a fish hook (220) and a barrier or shield (227) mounted in a position relative to the fish hook (220) such that the barrier (227) reduces or prevents hooking of a seabird or turtle by the fish hook or ingestion of the hook by a seabird or turtle. The apparatus includes a degradable component (226) that degrades when placed in water such that when the degradable component degrades the barrier moves away from the position relative to the fish hook or no longer exists to allow the fish hook to be taken by a fish. The degradable component (226) may be a retaining means or a mounting means. The degradable component may form part of, or all of, the barrier.

The invention discloses organic compound fertilizer suitable for clayed soil and a production method thereof. The components in the organic compound fertilizer comprise, by weight, 8-12 parts of fly-ash particles, 20-30 parts of soybean cake fertilizer, 15-18 parts of seabird faeces, 20-25 parts of corncob particles, 3-4 parts of potassium sulfate, 2-3 parts of ammonium phosphate, 5-8 parts of urea, 0.5-1 part of sodium borate, 5-8 parts of egg shells and 120-160 parts of distilled water. According to the organic compound fertilizer suitable for the clayed soil and the production method thereof, through the fact that the diameters of the particles are large, the different particles form large particle gaps in the clayed soil, and the cultivability and the permeability can be improved by the application of the fertilizer to the clayed soil; the self gaps inside corncobs are convenient for liquid fertilizer after fermentation to be absorbed in the impregnating process, a plenty of nutrient elements beneficial to plant growth are absorbed inside, the adhesion of plant root systems is facilitated, and the growth of plants in the clayed soil is facilitated.

The invention discloses a flying-wing-shaped closed sound-proof screen, which comprises a flying-wing-shaped sound-proof screen main body, a sound-proof tail section, and side screens; the flying-wing-shaped sound-proof screen main body is composed of a plurality of flying-wing-shaped sound-proof screen sections; The flying wing-shaped sound-proof screen section is provided with a left-wing sound-proof screen and a right-wing sound-proof screen; the shapes of the left-wing sound-proof screen and the right-wing sound-proof screen are similar to those of seagulls when they fly; the left-wing sound-proof screen is provided with a left front frame, a left Light-transmitting sound-insulating sheet; the right-wing sound-insulating screen is provided with a right front frame and a right light-transmitting sound-insulating sheet; the beneficial effect of the present invention is that a pair of flying wings of seabirds are integrated into the sound-insulating screen in this design, and a flying-wing-shaped sound-insulating screen is provided. It is composed of sections; it forms a natural transition of space, vision and light; the shape is simple and light; and the sound insulation effect is better and the structure is stronger.

The invention discloses a rack transmission swing arm mechanism comprising a bottom plate, track plates are fixedly connected to the left side and the right side of the front end of the bottom plate,and obliquely-arranged track grooves are formed in the surfaces of the track plates. The invention relates to the field of bionic machinery teaching models. According to the rack transmission swing arm mechanism, limbs such as fins and wings of organisms are simulated through an elytron device, the movement vividly shows the swimming movement of the organisms such as sea turtles and sea birds in water, the contraction movement of the fins and the wings is simulated through the transmission device, the actual movement characteristics of animals are better fitted, the authenticity is greatly enhanced, and academic research is facilitated. And the mechanism is more convenient to adjust and more flexible to use in the mode that a transmission disc and a first steering shaft are mutually sleeved and connected in a penetrating mode. The problems that an existing model is difficult to effectively simulate action characteristics of fins, wings and the like of animals, the teaching effect is not vivid enough, students are difficult to understand biological actions, and academic deep research cannot be well carried out are solved.
