Для оптимизации процесса облова прудов сооружают рыбоуловители, конструктивные особенности которых могут быть достаточно специфическими. Как правило, их сооружают в виде расширенного канала трапециевидной или прямоугольной формы, размером, который зависит от площади пруда и вероятного количества сконцентрированной рыбы. Рыбоуловители располагают по большей части в верхней части водоспуска, лучше параллельно каналу водоспуска. Для выращивальных прудов рыбоуловители могут иметь ширину по дну 2,5-3,5 м, длину 10-20 м.
Для нагульных прудов площадью от 50 до 250 гектар ширина рыбоулавливателей по дну может составлять 7-10 м при длине от 35 до 110 м с глубиной слоя воды около 1 м. Соотношение массы рыбы и воды при непродолжительном удерживании рыбы может составлять 1:4 - 1:5. При удлинении периода содержания рыбы в рыбоуловителе до нескольких недель и больше это соотношение целесообразно поддерживать на уровне 1:8 - 1:10. При передержании улова в рыбоуловителях необходимо обеспечить достаточную проточность воды и постоянно контролировать состояние рыбы.
Обязательным условием высокой культуры производства на специализированных рыбоводческих прудах является возможность периодического их полного освобождения от воды и просушки. Неравенства дна прудов создают впадины, в которых скапливается рыба, и усложняют её облов. Поэтому ложе прудов необходимо планировать таким образом, чтобы можно было быстро и полностью обловить всю выращенную рыбу. Такая подготовка дна достигается его уклоном в сторону водоспуска, созданием более глубокого центрального канала (канавы) с уклоном к водоспуску и менее глубоким боковым осушительным (мелиоративных) канавам с уклоном к центральной части пруда. Ширина мелиоративных (осушительных) канав по дну - не больше 1 м, глубина - 40-50 см. Около водоспуска центральная сборная канава расширена и образует рыбосборную яму где концентрируется рыба, которая осталась невыловленной после сброса основной массы воды. Глубина водосборной ямы одинакова с глубиной центральной канавы, а ее дно должно совпадать с уровнем порога стояка донного водовыпуска; площадь зависит от размера прудов и может изменяться от 15 до 30 м2. Количество боковых канав зависит от рельефа дна пруда. Таким образом, вся осушительная (мелиоративная) сеть состоит из канав, размещенных в виде лучей, что расходятся от центральной канавы. Такая подготовка ложа спусковых прудов дает возможность осушить дно, потом более мелкие боковые канавы и, в конечном итоге, центральную сборную канаву. Для поддержания надлежащего функционального состояния мелиоративной сети её необходимо ежегодно очищать от намула. Наличие мелиоративной сети каналов также способствует улучшению экологического состояния водоемов в следующий период их эксплуатации.
Существенному повышению производительности производства и облегчению труда в прудовом рыбоводстве способствует механизация производственных процессов.
