Here we look at 6 ways Seacloud can help reduce your feed costs and give you a better overview of the feeding environment
Here we look at 6 ways Seacloud can help reduce your feed costs and give you a better overview of the feeding environment
1. Control of oxygen saturation in the cage
2. Control of temperature in the cage
3. Control of power conditions
4. Control of salt content in the water
5. Control of feed inventory on the fleet
6. Overview of wind speed
With the help of the Seacloud portal and oxygen sensors from Seacloud, you always have control of the oxygen level in the cage. If you notice that your fish seem lethargic or have a poor appetite, it could be because the oxygen saturation has dropped. Look at the trend over time and learn to interpret the data. If the saturation drops steadily over a long period of time, it may be because the sensor has not been cleaned and is therefore showing incorrect values. If, on the other hand, you see that the O2 percentage has dropped more quickly and varies more in relation to, for example, the tide, it may be that the low figures are real. If the saturation is very low, it can be an advantage to pause feeding. Fish use more of the oxygen in the water when they move more quickly, such as during meals. If pausing feeding does not help, it may be a good idea to raise the lice skirt if it is fitted, or see if net cleaning is necessary, or if the density/biomass is too high.
Just as you have your own comfort temperature, salmon have their own comfort temperatures. In summer and fall, salmon can be affected by higher temperatures, because higher water temperatures result in lower oxygen saturation in the water. In addition, salmon require higher oxygen saturation at higher temperatures (forskning.no). When using the Seacloud portal, it is easy to adjust threshold values as the water temperature changes. If you want to be alerted when oxygen saturation falls below 75% in winter, for example, you can change to a higher threshold in summer at the touch of a button. At low winter temperatures, the fish may have reduced interest in the feed, as well as lower utilization of the feed due to reduced metabolism - and thus it may be profitable to adjust the intensity, or pause feeding completely in order not to increase the feed factor.
Are you feeding using an underwater camera and struggling to find the pellets? If so, the current may be so strong and the drift so great that the feed ends up out of the cage before the fish can get hold of it. With our current sensor, you have good control of local variations in the current around your facility. You can see the speed and direction at 3 different depths at the same time. If there is a lot of current, it may be worth reducing the feeding intensity and feeding at a shallower depth. It's easy to keep track of when the current speed drops again and you can return to a normal feeding regime.
Our salinity sensors give you good control of the salt content, while also showing the water temperature. High salinity is worse for the fish the lower the water temperature, and we can see increased mortality at ppt of around 30, combined with very low temperatures. In addition, there are a number of national and international customer requirements for monitoring water quality (GlobalGAP, ASC, etc.) where salinity is an important part of measuring quality (Fishguard).
Anyone who has fed salmon knows how frustrating it is to suddenly run out of feed during a meal. There can be a number of reasons for poor feed inventory control; incorrect calibrations, equipment failures, incorrect filling information from feed boats or poor routines. A visual inspection is also difficult to get accurate due to deep, poorly lit silos. We offer affordable and reliable feed silo sensors that give you good measurements of feed inventory. If you know in advance that a silo is about to run out, you can take action before feeding starts, thus avoiding production stoppages. In addition, a better inventory overview gives you good tools for solving silo logistics (how much feed should you fill where?).
Having a good overview of the wind speed when feeding sites from a growth center can be a useful tool. On good weather days, it may not be so useful. But if the wind speed is very high, it can be difficult to get the feed to hit where you want in the cage. It's not always possible to see where the feed hits the surface of the water with the surface camera, for example when there's a strong headwind or heavy rainfall. In such cases, it can be useful to know whether it's worth starting to feed at all, or whether it's better to wait until the weather has cleared.
In addition to these products that can help with feeding, we have products that can digitize and streamline other parts of the operation as well. For example, we supply pH sensors for grinding tanks, circulation pipes, etc. so that you never have to wonder if the fish waste has been properly ensiled. We also offer engine integrations, so you get an overview of, among other things, rpm and oil level directly in the Seacloud portal. Sounds great to have everything in one place, doesn't it?
