Description

Изобретение относитс  к рыбоводству, в частности к устройствам дл  нереста рйб, дл  использовани  его в естественных услови х, в местах нереста рыб.The invention relates to fish farming, in particular to devices for spawning riba, for use in natural conditions, in places of spawning of fish.

Известно устройство дли нерестаi рыб включающее основание с субстратом, сетное ограждение № механизм перемещени  последнего, при этом i последнийсостоит из тросов, поплавков и грузил, а сеггное ограждение установлено по бокам основани  1 .It is known a device for spawning fish that includes a base with a substrate, a net fence, a mechanism for moving the latter, while the latter consists of cables, floats and weights, and a segmental fence is installed on the sides of the base 1.

Однако в известном устройстве сетное ограждение не перекрывает полностью в верхней части основание, что позвол ет хищникам выедать оплодотворенную икру.However, in the known device, the net fencing does not completely cover the base in the upper part, which allows predators to eat away the fertilized eggs.

Целью изобретени   вл етс  повышение надежной защиты икры рыб от хищников .The aim of the invention is to increase the reliable protection of fish eggs from predators.

Цель достигаетс  тем, что в предлагаемом устройстве механизм перемещени  выполнен в виде транспортера, а сетное ограхсдение закреплено на одной из его ветвей с двух сторон, при этом основание с субстратом размещено между ветв ми транспортера.The goal is achieved by the fact that in the proposed device the transfer mechanism is made in the form of a conveyor, and the net fence is fixed on one of its branches on both sides, while the base with the substrate is placed between the branches of the conveyor.

На фиг. 1 показано предлагаемое устройство; на фиг. 2 - то же, вид сверху; на фиг. 3 - то же, вид сбоку; на фиг. 4вид по стрелке А на фиг. 3.FIG. 1 shows the proposed device; in fig. 2 - the same, top view; in fig. 3 - the same, side view; in fig. 4 view along arrow A in FIG. 3

Устройство состоит из основани  1 с субстратом, установленного на катках 2, размещаемых на направл ющих 3, сетного ограждени  4 и механизма перемещени . Последний представл ет собой транспортер, состо щий из ведущего и ведомого валов 5 и 6, охватывающей их цепи 7, закрепленных на последней планок 8 посредством опор 9 и привода Ю с выключателем 11. Транспортер закреплен таким образом, что основание расположено меж,чу его ветв ми.The device consists of a base 1 with a substrate mounted on rollers 2 placed on guides 3, a net fence 4 and a moving mechanism. The latter is a conveyor consisting of leading and driven shafts 5 and 6, covering their chain 7, fixed to the last rail 8 by means of supports 9 and driving U with a switch 11. The conveyor is fixed in such a way that the base is located between, its branch mi

Сетное ограждение 4 закреплено на транспортере на одной из eixi ветвей с двух сторон посредством планок 8 и соединено сВыключателем 11 дл  фиксации положени  его над основанием 1..The net fence 4 is fixed on the conveyor on one of the eixi branches on both sides by means of the strips 8 and connected to the switch 11 to fix its position above the base 1 ..

Устройство работает следующим образоМг 362 В преднерестовом в нерестовом nepIToS дах сетное ограждение 4 находитс  в положении, т.е. под основанием 1. В этот момент рыбы нерест тс . Как только кончитс  нерест рыб; включают привод 10 транспортера, сетное огражде ние 4 перемешаетс  и занимает верхнее положение до того момента, когда привод 10 отключитс  выключателем 11. В верхнем положении сетное ограждение 4 надежно закрывает основание 1 с субстратом и икрой от проникновени  на нег хищников. Перевод сетного ограждени  в ниж}{ее положение производ т после тог как личинки рыб разовьютс  в жизне способных мальков. Формула изобрет е.н и   Устройство дл  нереста рыб, включаюее основание с субстратом, сетное ограждение и механизм перемещени  последнего, отличающеес  тем, что, с целью повьпиени  надежной защиты икры рыб от хищников, механизм перемещени  выполиеи в виде транспортера, а сетное ограждение закреплено на одной из его ветвей с двух сторон, при этом основание с субстратом размещено между ветв ми транспортера. Источники информации, прин тые во внимание при экспертизе: 1. Авторское свидетельство СССР № 556756, кл. А 01 К 61/СО, 1975.The device operates as follows: 362 In prespawning spawning nepIToS dah, net fence 4 is in position, i.e. under the base 1. At this point, the fish spawn ts. As soon as the spawning of fish has ended; the conveyor drive 10 is turned on, the net fencing 4 is mixed and takes the upper position until the drive 10 is turned off by the switch 11. In the top position the net fence 4 reliably closes the base 1 with the substrate and caviar from penetration by non-predators. Translation of the net fence to the bottom} {its position is made after the fish larvae develop in lively fry. The formula of the invention is a spawning device for fish, including a base with a substrate, a net fence and a mechanism for moving the latter, characterized in that, in order to ensure reliable protection of fish eggs from predators, the mechanism moves in the form of a conveyor and the net fence is fixed on one of its branches on both sides, with the base with the substrate placed between the branches of the conveyor.
