Feng Shui in Agriculture & Farming

We always say that raising fish requires raising water first,Unsuccessful breeding,Water quality plays a very important roleActuallyExcept for waterWind also has a significant impact on aquaculture。

So what impact does wind have on aquaculture?

What is wind? Wind is a large-scale gas flow phenomenon。 On Earth, wind is formed by the large-scale movement of air。 In meteorology, wind is often described by its magnitude and direction。

From a size perspective, wind can be divided into gentle breeze, gale, storm, hurricane, typhoon, etc。 The stronger the wind, the greater the impact on aquaculture。 The damage caused by the typhoon rainbow this summer is still fresh in people’s memory, and the losses caused are both natural and man-made。 However, the magnitude of wind power is not controllable by humans and can only rely on the establishment of more robust facilities。

Although typhoons have a significant impact, this is not a common phenomenon。 In general, it takes a decade or even several decades for a major typhoon to occur。 But the direction of the wind is different, it is constantly affecting the fish pond。

Firstly, algae are affected by wind。 With the influence of wind, algae are blown downwind due to their small size and weight。 Therefore, under normal circumstances, due to the effect of wind, the density of algae downwind is higher than that upwind, photosynthesis is stronger, and dissolved oxygen is also higher than that upwind。

In addition to altering the distribution of dissolved oxygen in ponds by affecting the density of algae, wind can also scrape water with higher dissolved oxygen on the surface of the upwind area to the downwind area, resulting in higher dissolved oxygen in the downwind area。 Wind can also stir and directly dissolve oxygen from the air into water, increasing the dissolved oxygen content in the water。

Wind can also affect the stratification of dissolved oxygen in water。 Generally speaking, on clear days, whether it is the upwind or downwind, the dissolved oxygen in surface water is much higher than that in bottom water。 However, due to the effect of wind, the difference in dissolved oxygen between the upwind and downwind layers is greater than that in the downwind layer。

So what’s the point of knowing these? The significance is enormous!

We all know that dissolved oxygen can affect fish feeding。 Researchers have found that in adjacent ponds, it is only becauseThe placement of baiting machines varies。 In one pond, fish feed actively with a low feed coefficient, while in another pond, fish feed slowly with a low amount and a high feed coefficient.

If someone tells you that there is a Manchu Han feast set up at the corner of the sky and the sea, I’m sure you wouldn’t want to take the risk to eat。 Similarly, fish do not like to eat in harsh environments, and in low dissolved oxygen conditions, they may quickly swim away just by filling their stomachs hastily。 Therefore, the placement of the feeding machine becomes particularly important。 When placing the feeding machine, try to place it in the high dissolved oxygen area of the pond, so that the fish no longer feed in the sub dissolved oxygen area。 This can effectively reduce the feed coefficient and increase growth rate。
