Technical Analysis of Adjustments to Beam Trawl Fishing Gear and Methods
At present, beam trawl shrimp trawling has become one of the important operating methods of marine fishing in coastal fishing areas, and its output value as a proportion of the total marine fishery output value has risen year after year. Since this operating method belongs to single-boat bottom beam trawl operation, its gear design, rigging, operational adjustment, and fishing ground selection and other stages are all fairly highly technical, so even a slight oversight can affect shrimp trawling production. In particular, the adjustment techniques in beam trawl operation are the key to fishing production technology. For example, in production practice everyone often encounters this phenomenon: the same

Detailed Explanation of the New Technology for One-Time Massive Mushroom Flushing of Oyster Mushrooms
The so-called new technology for massive mushroom flushing refers to the use of a supporting set of techniques to force a one-time high yield at the first flush of mushrooms. This is a further improvement and strengthening of "simulated industrial cultivation technology," and practice has shown that the results are very good and that it can be promoted for use. This technology mainly consists of five steps: 1. Carry out virus elimination treatment on the spawn. "Good seed produces good seedlings" is a truth everyone knows, but indefinite preservation of spawn and continuous, unlimited subculturing can lead to problems such as trait degeneration or naturally carrying viruses and pathogens.

Detailed explanation of the production method for almond refreshing beverage
Almond refreshing beverage production process: raw material selection and impurity removal → washing and soaking → pre-boiling → peeling → debittering and color protection → rinsing → re-boiling → grinding → pulp-residue separation → almond juice → blending → filling base material → filling CO2 water → capping → inspection → labeling → packing → finished product. Key points of process operation: Water treatment. The water used for the beverage must meet the soda water quality requirements in QB926-84. The water used in the process must be tested and qualified after electrodialysis and other treatments before use. Preparation of almond juice. Selection: fresh, plump, mold-free almonds

How to manage fishing affairs in June? Key points that aquaculture farmers must read
June is the best period for aquaculture animals to feed heavily and grow rapidly, and it is also a stage when epidemics among aquaculture animals are prone to break out. Therefore, fishing affairs in June should be carried out around feeding and disease prevention. Feeding (1) Master the feeding amount. The daily feeding amount of different feeds as a proportion of the body weight of aquaculture animals in the pond is as follows: ordinary feed such as rapeseed cake and soybean meal, 6%-8%; pelleted compound feed, 2%-4%; for carnivorous fish such as mandarin fish and bass that are directly fed small fish and shrimp, 1%-2%; green

What are the precautions for winter fishing?
Remove debris from the pond before fishing. To ensure safe winter fishing, you must remove debris from the fish pond, such as tree stumps, branches, wire mesh, white pollutants, etc. Adapt to the pond conditions. Before fishing, do a good job of draining and filling the fish pond; if the pond water level is too deep, making it inconvenient to operate a seine net, the water level can be lowered to 1-1.5 m, but after fishing, immediately fill the water to above 2.5 m to increase the water level for insulation, so that marketable fish that have not reached standard size can overwinter safely, ready for continued profitable breeding next year. The net should be set gently and retrieved quickly. Remember, before setting the net,

What are the techniques for establishing a high-density, high-yield honeysuckle plantation?
Honeysuckle (Lonicera japonica) is a perennial semi-evergreen woody vine, also known as Erhua or Shuanghua, and is a traditional precious Chinese medicinal herb. The roots, stems, leaves and flowers of honeysuckle can all be used medicinally, but the main medicinal part is the dried flower buds, which have the effects of clearing heat and detoxifying, eliminating chronic inflammation and boosting human immunity. In recent years, with the intensification of honeysuckle development and the broadening of its application fields, market demand has grown ever larger. Improving cultivation techniques to raise the early-stage yield of honeysuckle and maintain the duration of its full-production period has become a major problem urgently needing solution in production. In recent years we

How to create the right environmental conditions for growing-finishing pigs (Part 1)
Intensive pig production is carried out under high-density housed conditions, and the microclimate inside the pig house is the main environmental condition. The microclimate of a pig house includes: temperature, humidity, wind speed, gases, sound, and so on. These environmental factors all directly affect the weight gain rate, feed utilization rate and ultimately the economic benefits of pigs. 1. Suitable temperature and humidity Pigs have a poor ability to regulate their own body temperature; they have only very few sweat glands that can help regulate it in hot weather, and only very little hair coat to resist the cold of winter. Therefore, pig houses must have good heat insulation and warmth retention, and

Two Key Techniques for High and Stable Yields of Yellow Catfish: Disease Control and Fishing Technology
In artificial farming of yellow catfish, the key technical measures for high and stable yields should focus on two things - disease control and daily harvesting of yellow catfish. Yellow catfish, also known as yellow catfish, yellow sprout head, yellow ding fish, yellow fish, yellow drum fish, river catfish, ga ya zi, river yellow catfish, Wallace's yellow catfish, mo ding, ounce fish, yellow horn, ga fish, yellow spine fish, yellow ox withered, grass withered, yellow cheek fish, ounce male fish and yellow bone fish, etc., is a small freshwater economic fish and a famous, special and excellent variety.
