Description

A kind of cultivating system carrying out feedstuff feeding according to water PH value
Technical field
The invention belongs to technical field of aquaculture, be specifically related to the field of carrying out feedstuff feeding according to the size of water body oxygen content, particularly relate to a kind of cultivating system carrying out feedstuff feeding according to water PH value.
Background technology
Dissolved oxygen is the lifeline that water fish class is depended on for existence.Dissolved oxygen is not only the required material ensureing prawn normal physiological function and healthy growth, is again the required material of improvement water quality and bottom, is the key factor that maintenance nitrogen cycle is carried out smoothly.Aquatic animal lives in water, carry out metabolism, and its prerequisite is exactly that oxygen in water should be sufficient.Existence, the growth relationship of dissolved oxygen and aquatic animal are close, and the high appetite that can promote cultivated animals of pond water dissolved oxygen, improves the availability of feed, quickening is grown, otherwise the dissolved oxygen in water is low, its grazing rate and efficiency of feed utilization will be subject to suppression in various degree.Dissolved oxygen in water is high, then water quality has fertilizer, work, refreshing feature, and fish honey stomach, efficiency of feed utilization is high.
According to interrelated data display, the feed coefficient of fish when dissolved oxygen 3mg/L, is twice than increasing during 4mg/L, grows the long speed of the sashimi (raw fish) 20%-30% faster than the fish of growth in dissolved oxygen 4mg/L in dissolved oxygen 7mg/L, and the low 30%-50% of feed coefficient.When dissolved oxygen in water reaches more than 4.5mg/L, the appetite of fish, shrimp strengthens very obvious; When reaching more than 5mg/L, feed coefficient reaches optimum value.In current aquaculture process, the dissolved oxygen level in water does not often reach due requirement and affects the price of deed.Therefore, in order to ensure that the best limit of cultivated animals utilizes the feed of throwing something and feeding, reach the object of fully growth, the dissolved oxygen in water should be not less than 5mg/L-7mg/L.Therefore, when high yield, high-density breeding, to often measure dissolved oxygen index in breeding process, take to add water and change water, improve substrate, use the measures such as aerator, reach dissolved oxygen abundance, be beneficial to the object digesting and assimilating, reduce feed coefficient.
The height of water body dissolved oxygen amount directly affects the food ration of fish and the size of abilities of digestive and absorption.Dissolved oxygen content in water is high, and the vigorous digestibility of ingesting of fish is high, and growth is fast, and efficiency of feed utilization is also high; Dissolved oxygen content in water is low, and fish, due to physiological inadaptable, make to ingest and digestibility reduction, and consume more energy.Therefore poor growth, feed rate is low.At present, most raiser throws something and feeds regardless of dissolved oxygen in water situation every day at regular time and quantity.If water body is in anaerobic condition, fish amount can obviously reduce, and cause feed waste serious, feed coefficient obviously raises, and cause the rising of aquaculture cost, culture benefit is low; And cause water environment degradation, time serious, water body ammonia nitrogen, nitrite exceed standard and cause fish dead, bring economic loss.
Simultaneous temperature mainly plays control action to Metabolism of Fishes reaction rate as controlling elements, thus affects the g and D of fish.In Suitable ranges, the physiological metabolism degree of fish and being proportionate property of temperature, prescribe a time limit when temperature is elevated to the upper of optimum temperature, often significantly rise along with physiological metabolic rate.Temperature not only has significant impact to metabolism degree, also on fish ingest and intensity and grazing rate and digestibility all have and directly and indirectly affect.In suitable temperature range, the rising of temperature can promote the ingesting of fish, absorption and digestion, otherwise can suppress the ingesting of fish, absorption and digestion to a certain extent.
And the growth of pH value to fish has a significant impact, if breeded fish, water pH value is on the low side, there is no again external special contamination, just can judge this water body likely lower hardness, humus is too much, carbonic acid gas is higher and dissolved oxygen amount not enough, and also can judge that this water body photosynthesis of plant is not prosperous or aquaculture organism density is excessive or microbial metabolism is suppressed, whole metabolism systemic metabolism is slow simultaneously.If pH value is too high, also may be that hardness is inadequate, and plant propagation is too vigorous, it is not enough that photosynthesis crosses humus in strong or pond.
In breeding process, also need the turbidity (transparency) controlling water body, water transparency mainly changes along with the turbidity of water.Turbidity be mixed with in water various for bacterial components comprise plankton cause muddy degree.
Of the prior artly as application number be: CN201210404145.9, summary is: the invention discloses a kind of aquaculture feeding system, aim to provide one effectively to solve feeding machine feed waste and feed can be caused in feeding procedure by the time of tide, the feeding system of the problem that feeding machine cannot work.It comprises hopper, is provided with interlayer below the end face of hopper cavity, and interlayer lower surface is provided with the first vertical guide rod, and being provided with below interlayer can along the baffle plate of the first vertical guide rod movement, and the buoyancy of this baffle plate is greater than gravity; Described interlayer is provided with some top discharge holes, and baffle plate is provided with some bottom discharge holes, and top discharge hole and bottom discharge hole are interspersed; Interlayer upper surface middle part is provided with motor, is provided with vertical screw rod in casing cavity, and this vertical screw rod is connected with rotor with interlayer through baffle plate, is provided with nut and this nut sleeve is located on vertical screw rod in the middle part of baffle plate; The lower end of vertical screw rod is provided with coaxial polished rod, and the bottom of described polished rod is provided with impeller; The body side relative with impeller is provided with some relief holes.
