Product Description

Project Background

Current Situation and Monitoring Difficulties of Aquaculture

Current status of aquaculture

The traditional breeding model relies on manual experience management, which has the following problems:

Water quality management is extensive
Key indicators such as dissolved oxygen and ammonia nitrogen fluctuated greatly, and the timeliness of manual sampling was poor, making it difficult to regulate in real time
Disease prevention and control lags behind
Sudden drops in dissolved oxygen or the spread of pathogens can easily lead to large-scale deaths, and there is a lack of early warning mechanism

The tailwater discharge exceeded the standard
Ammonia nitrogen and other pollutants are discharged beyond the standard in aquaculture tailwater, which intensifies the eutrophication of water bodies
Insufficient equipment stability
Sensors are susceptible to salt corrosion and algae adhesion, resulting in high maintenance costs and low data reliability

In order to accelerate the green development of the aquaculture industry, relevant national policies and regulations have been introduced in recent years.

2021 "Opinions of the Ministry of Agriculture and Rural Affairs on Promoting the Green Development of Aquaculture Industry"

It is clearly required to promote intelligent monitoring equipment to achieve standard discharge of aquaculture tailwater.

2023 "National Fisheries 14th Five-Year Development Plan"

Emphasize the construction of a digital supervision system for aquaculture, strengthen epidemic early warning and drug traceability.

2024 "Aquaculture Tailwater Pollutant Discharge Standards"

Formulate limits for key indicators such as ammonia nitrogen and total phosphorus to promote the green transformation of the industry.

Monitoring difficulties

Water quality parameters are dynamically complex
Dissolved oxygen, pH, temperature and other indicators are affected by feeding, weather, and microbial activities, and need to be monitored frequently and in multiple dimensions
Insufficient response to emergencies
Events such as sudden drops in dissolved oxygen and algal blooms require millisecond early warning and automated intervention
The equipment has weak anti-fouling ability
Water salinity and algae adhesion lead to sensor drift, and traditional equipment has a short life and is difficult to maintain

Table 1. The importance of water quality indicators to aquaculture

Water quality indicators	Meaning
Dissolved oxygen (DO)	Reflecting the oxygen supply capacity of the water body, low values lead to suffocation of fish, and high values indicate excessive reproduction of algae.
Ammonia nitrogen	Toxicity index, gill tissue damage caused by excessive concentration, and the feeding rate and biological filter efficiency were optimized through monitoring.
pH	It affects fish metabolism and pathogen activity, and abnormal fluctuations indicate the risk of acidification or alkalization of water bodies.
Turbidity	The suspended solids content was characterized, and the high turbidity hindered light transmission, affecting algal photosynthesis and fish feeding behavior.

or the monitoring focus of aquaculture, Probest has built an integrated monitoring system of "perception-transmission-decision", which is composed of high-precision water quality sensors, which can realize real-time monitoring of dissolved oxygen, ammonia nitrogen, pH, turbidity, temperature and other parameters. Through low-power remote measurement and control terminals, real-time data is transmitted to the smart breeding platform to accurately control the key indicators of the breeding area and ensure breeding safety.
