даю текст д-ра Адриана Таппина в оригинале(это он написал мне по поводу транспортировки)
Square-bottom bags are ideal for shipping fish because they sit upright in shipping boxes and do not have “folds” where fish can concentrate and become trapped. Another benefit of the square-bottom bag is that it allows for a larger surface area between the oxygen and the water, maximising oxygen diffusion into the water reducing localised zones of oxygen depletion. The size of the bag that is used depends on the number, size, and species of the fish being shipped. In square-bottom shipping bags, the oxygen gas volume to water volume ratio is generally 60% oxygen to 40% water.
Common packing densities used in the commercial shipping of rainbowfishes and based on a single seven-litre capacity size bag is 150 individuals at 25 mm size, 100 at 50 mm, and 50 at 65 mm. After packing, the bags with fish are placed in an expanded polystyrene foam box, usually four to eight bags to a box, to provide thermal insulation to prevent sudden changes in temperature of the transport water, especially when the consignments are in the cargo hold of aircraft during air transport.
The health of the fish can be affected by changes in water quality parameters while in the plastic bags during the shipping process. The parameters to be considered are temperature, dissolved oxygen, pH, carbon dioxide, ammonia, and osmoregulatory dysfunction. The rate of change of each parameter is affected by the weight and size of fish to be transported and the duration of transport.
