Description

Fish safety detection and safety injection sampling device and method Technical Field The invention relates to the technical field of fish safety detection equipment, in particular to a fish safety detection and safety injection sampling device and method. Background In industries such as aquaculture, fishery resource investigation, fish genetic breeding, disease prevention and control, aquatic product safety detection and the like, operations such as individual identification, physiological index measurement, drug injection or sample collection and the like on living fishes are key links for guaranteeing the cultivation safety and improving the cultivation quality. However, the traditional operation mode has a series of remarkable technical bottlenecks and animal welfare problems, and severely restricts the standardization, large-scale development and accuracy of scientific research data of the industry. The current mainstream operation mode is highly dependent on manual bare hands or the use of simple net tools, towels and other tools to catch, transfer and forcefully fix the fish body, and the process is a very strong stress source for the fish. The fish is used as a lower vertebrate, the stress response system is extremely sensitive, and severe struggling and water separation environment can lead to the rapid increase of stress hormone levels such as cortisol and the like in the fish body, so that a series of physiological disorders are induced, including hyperrespiratory metabolism, immunity decline, electrolyte imbalance and the like, the stress directly threatens the survival rate of an operating individual, especially the direct economic loss is easily caused in the operation of rare parents or high-value offspring, the subsequent growth and development, reproductive performance and the authenticity of experimental data can be influenced, for example, the blood biochemical index or the immune parameter after stress can deviate from a normal value seriously. Furthermore, the conventional retaining method violates the basic physiological requirement of the fish, and the fish is in choking state in a very short time because the fish performs gas exchange in water through the cheek yarn, and the cheek yarn can lose function due to adhesion after the fish leaves water. Even if an operator intends to rapidly complete the work, the long-time water-leaving operation in the operation process can cause irreversible damage to the cheek tissues and aggravate anoxic stress, and in addition, the important physical and immune barriers of the mucus layer on the surface of the fish body after water leaving are also very easy to fall off due to friction, so that the risk of subsequent infection of pathogens is increased. Meanwhile, the existing detection and operation flow is usually in a sectional shape and discretization shape, for example, one operator firstly drags out and fixes the fish, the other operator scans codes or visually identifies the fish, then the fish is handed to a third operator for B ultrasonic exploration, finally, the hand-over is possibly needed to be changed for injection or sampling, each fish needs to be transferred and fixed repeatedly for a plurality of times, the total operation time is long, the efficiency is low, more importantly, each handover is a new round of stimulation to the fish body, and under the detection scene of a plurality of fishes and a large quantity, the mode has high labor intensity and high personnel cost, and the consistency of operation standards is difficult to ensure.
