You want – nay, need – a massage. You've spent the past year either perched on a dining chair or supine on your sofa, and it hasn't done your back/neck/wellbeing any favours. Ditto your decision to jump spine-first into bodyweight exercises.

Problem is, the idea of sharing a small room with a touchy-feely stranger right now fills you with understandable dread. No amount of Enya or incense could allow you to relax. That's why we've rounded up the best percussive massage guns on the market; deep soft tissue manipulators that help recovery, decrease soreness, improve circulation, address posture issues and help you get more out of your muscles. They're also pretty enjoyable, too.
So how do massage guns work? Well, they`re designed to combat muscle soreness and aid recovery. It`s a deep tissue massage of sorts, achieved through rapid percussive movements that stimulate muscles, enhance blood flow and soften knots. You can use them while warming-up or post-work out, and they feel pretty good too, hitting at all the right pressure points that can enhance the production of endorphins. At the very least, massage guns can provide some short-term relief for problem areas.
[They may often look like power tools, but the benefits of massage gun include decreased muscle tension, relaxed muscles, and promoted blood flow," says Dr Daniel Giordano, CMO of Bespoke Treatments. [We use one on a daily basis, and it can be used before, during or after a work-out."
Shrimp shellfish should pay attention to eight points
One of the key reasons is that there are significant differences in the areas, pools, species, and even within different sections of the same shrimp pond. For example, shellfish can be found in various shrimp ponds, with some growing rapidly near the water inlet, while others thrive closer to the outlet. In certain ponds, eutrophication is severe, which not only hinders shrimp growth but also negatively affects shellfish, sometimes leading to their death. This highlights the importance of not blindly applying polyculture methods from other regions. Instead, we should adopt a scientific approach tailored to our specific conditions.
Secondly, it's crucial to select high-quality shellfish species that can tolerate eutrophication, adapt to temperature fluctuations, and survive within the salinity range of shrimp ponds. The chosen varieties should grow quickly, have high market value, and be resilient to environmental changes.
Thirdly, a rational distribution of shellfish is essential for ease of harvesting. It's recommended to concentrate stocking in 15% to 25% of the total pond area. Ponds with good water quality at the outlet should be seeded appropriately, while those with poor water quality should be seeded near the inlet to maximize survival rates.
Fourthly, timely seedling planting is important. If possible, seedlings should be introduced as early as possible, but spring seeding should be done after the pond has been properly prepared.
Fifthly, the density of both shrimp and shellfish should be adjusted based on pond size to optimize ecological balance. Higher shrimp densities lead to increased feeding activity, boosting primary productivity, which allows for higher shellfish stocking. Maintaining an appropriate shrimp density is vital for preventing water quality degradation.
Sixthly, controlling the depth of the shrimp pond is necessary. While deeper water can increase shrimp biomass, it also leads to more organic matter accumulation at the bottom, reduced light penetration, and slower water flow, which is harmful to both shrimp and shellfish. Therefore, the depth should be adjusted according to local conditions rather than being as deep as possible.
Seventhly, investing in additional aeration equipment is essential. Currently, many Chinese shrimp farms rely on water exchange to manage water quality, but this often results in loss of beneficial organisms and reduced productivity. Poor water quality is frequently caused by oxygen deficiency. By reducing water exchange and adding aeration systems, water quality can be significantly improved, enhancing the overall ecological efficiency of the pond.
Lastly, routine management and regular monitoring are critical. Frequent inspections, sampling, and observations of water quality and shrimp/shellfish growth should be conducted. Establishing a consistent measurement and recording system helps identify anomalies early, allowing for prompt corrective actions and preventing major losses.
