Embodiment 1

[0041] see Figure 1-6 , a floating fish egg monitoring device, it includes a base plate 1 for supporting and installing the whole device, a double-layer casing 2 is fixed on the top of the base plate 1, and two ends of the bottom of the base plate 1 are installed for monitoring the flow rate. the flow rate monitoring device; the bottom layer of the double-layer shell 2 is provided with a main infrared camera and a backup infrared camera, and the middle part of the bottom layer of the double-layer shell 2 is suspended and installed for monitoring the main infrared camera and the backup infrared camera A glass cover cleaning device for cleaning; the upper layer of the double-layer casing 2 is provided with a flow rate data storage 5 and an infrared photography data storage 9, and the top of the double-layer casing 2 is provided with a top shackle 8, and the double-layer casing 2 Symmetrically arranged side shackles 11 are arranged on the side wall of the layer shell 2; a draina...

Embodiment 2

[0052] A method for using a drifting fish roe monitoring device, comprising the following steps:

[0053] Step1: Float the entire monitoring device on the water surface through the bottom plate 1, fix the position of the entire monitoring device through the fixing rope 30, and fix the shore fixing pile 34 and the recovery rope 33 at the same time;

[0054] Step2: After fixing all monitoring devices, start the front-end flow velocity measuring instrument 20 and the main infrared micro-camera 28 in the starting device, start monitoring the flow velocity situation of the river section and the number of floating eggs and the number of hatched larvae;

[0055] Step3: The flow rate data monitored together by a single monitoring are respectively stored in the flow rate data storage 5 and the infrared photography data storage 9;

[0056] Step4: The data monitored by each monitoring device is transmitted to the signal base station on the shore through wireless signals, and then transmi...

Embodiment 3

[0059] Using this monitoring device and method to carry out the ecological regulation experiment of cascade reservoirs in the lower reaches of the A River, most of the floating fish eggs will have a relative specific gravity slightly larger than water after they absorb water and expand, and they will gradually sink to the bottom of the river bed in a still water environment. It is easy to cause dysplasia or even death of fish eggs. This monitoring equipment and dispatching method mainly ensure that the downstream river section of the fish spawning ground that produces floating eggs has a flow rate of 0.27m / s or more, effectively improving the safety of floating fish eggs in the lower reaches of the A River. hatch rate.

[0060] Therefore, for fish that lay floating eggs, the main spawning grounds in the lower reaches of the A River are at the spawning grounds, 5km downstream of the spawning grounds, 10km downstream of the spawning grounds, 15km downstream of the spawning ground...

Abstract

The invention provides drifting roe monitoring equipment and a cascade reservoir dispatching method for improving hatchability. The drifting roe monitoring equipment comprises a bottom plate for supporting and installing the whole equipment, wherein the top of the bottom plate is fixedly provided with a double-layer shell; the two ends of the bottom of the bottom plate are provided with flow velocity monitoring devices for monitoring flow velocity; a main infrared photographing device and a standby infrared photographing device are arranged on the bottom layer of the double-layer shell; a glass cover cleaning device used for cleaning the main infrared photographing device and the standby infrared photographing device is installed in the middle of the bottom layer of the double-layer shell in a suspended mode; the upper layer of the double-layer shell is provided with a flow velocity data memory and an infrared photography data memory; the top of the double-layer shell is provided with a top hook; the side wall of the double-layer shell is provided with side hooks which are symmetrically arranged; and a drainage device is arranged in the bottom plate. The problem that the drifting roes sink to the bottom and are dysplastic and even die in the technical background is solved, and the hatchability of the drifting roes at the downstream of the cascade reservoir is increased.

Description

technical field [0001] The invention relates to the fine control field of cascade reservoirs, in particular to a monitoring device for floating fish eggs and a cascade reservoir scheduling method for increasing hatching rate. Background technique [0002] Optimal dispatching of cascade reservoirs is a typical nonlinear, multi-dimensional, and strongly constrained engineering problem. It is an important measure to improve my country's energy structure, and it is also a hot topic in the field of hydropower dispatching in my country. With the development of large-scale hydropower resources in recent decades, the operation of cascade reservoirs has had a certain impact on the spawning and reproduction of downstream fish, and the demand for spawning and reproduction of fish downstream of the reservoir can be alleviated by adjusting the operating procedures of the reservoir is a current research hotspot. However, at present, most of the ecological regulation studies on downstream...
