Abstract
The utility model relates to an artificial fish bank spawning reef, more specifically, is a cuttle fish spawning reef which is made up of at least one attachment fixed on the sinker. Said attachment is ligated bundle of the tamarisk willow branches or Artemisia annual branches. A boom rope, which has a buoy, is tied on the lower part of the bundle attachment or the sinker. The utility model is simple in making, low-cost and with high adhesive rate of fertilized eggs, manageable, economical as well as practical, at the same time without damaging the spawning parents.
Description
Technical field:
The utility model relates to the artificial fish shelter reef of laying eggs, and is a kind of golden cuttlefish reef of laying eggs specifically.
Background technology:
Golden cuttlefish is one of important economic siphonopods of China's sea fishery, the main fishing ground of China golden cuttlefish at haze at the sunshine hilltop, Shandong, Qingdao, Huanghai Sea middle part and northern.As far back as nineteen fifty-nine; China Zhu Yuanding professor just proposes will breed and this valuable source of protective money cuttlefish in west of pacific ocean fishery study executive session; but after the last century the eighties; along with the development of fish production and improving constantly of modernization level; golden cuttlefish is faced, and to fish for pressure increasing; the environment and the production order of spawning ground that golden cuttlefish is present and propagation protection zone are on the hazard; the regeneration capacity of its resource is difficult to bear the catching intensity that grows with each passing day; magnitude of recruitment significantly descends, and its fish production is obviously failed.
Golden cuttlefish is as a kind of landrace of preciousness, rises in 1992 to be put into Shandong Province's local supplies propagation plan.What take is a kind of half artificial fecundation protected mode to propagation, and the cuttlefish cage that is about to be attached with golden cuttlefish fertilized egg collects, and concentrates and renders to a Dinghai District, it hatch naturally to breed to protect manage.The enforcement period of the ninth five-year plan, nearly 1,000,000 yuan in coastal infusion of financial resources at sunshine of Shandong Province carry out the propagation of golden cuttlefish and release, and have created favorable economic benefit, though fair with the cuttlefish cage as golden cuttlefish propagation adherance effect, also exist some problems simultaneously.The one, be subjected to the influence of fishery resources, fishing ground environment and productivity effect in recent years, the cuttlefish cage quantity that puts into production sharply reduces, and propagation is originated with adherance becomes the outstanding problem of restriction cuttlefish propagation industry and further expansion scale; The 2nd, the cuttlefish cage is made complicated, and cost is higher, is unsuitable for the extensive propagation of golden cuttlefish; The 3rd, cuttlefish cage itself is a purpose to fish for, the infringement parent of laying eggs, and the habit that the incompatibility golden cuttlefish repeatedly lays eggs has influenced the egg laying amount of golden cuttlefish.For the stable and further golden cuttlefish propagation scale that enlarges, improve enrichment procedure, seeking new adherance then becomes the important topic that propagation work faces.
Summary of the invention
The purpose of this invention is to provide a kind of golden cuttlefish reef of laying eggs, to remedy the deficiencies in the prior art.
The technical solution of the utility model is fixed in the reef of laying eggs that the adherance on the sinker is formed by at least one.
Above-mentioned adherance is the Chinese tamarisk branch or the artemisia annua branch of ligation bunchy.
Tied a well rope rope on the adherance bottom of above-mentioned bunchy or the sinker.And be that a buoy is arranged on the well rope rope.
The utility model of constructing is thus made simple, and cost is low, and fertilized egg adhesive rate height, is convenient to management, and is economical and practical, also do not damage the parent of laying eggs simultaneously.
Description of drawings:
Fig. 1 is a basic structure schematic diagram of the present utility model.
Fig. 2 is an on-the-spot laying structure schematic diagram of the present utility model.
Wherein 1, adherance 2, sinker 3, well rope rope 4, buoy.
Embodiment
As Fig. 1, the utility model is fixed in the reef of laying eggs that the adherance 1 on the sinker 2 is formed by at least one.
Above-mentioned adherance 1 is the Chinese tamarisk branch of ligation bunchy or artemisia annua branch.With the Chinese tamarisk branch of ligation bunchy or the Shu Duan of artemisia annua branch, be fixed in one with cement pouring, the sinker shape can be selected trapezoidal shape, as Fig. 1, also other square body.For ease of operation, when cement pouring sinker, can set in its side be convenient to the bondage of well rope rope fasten ear (figure omits).
As Fig. 2, for ease of management, in adherance 1 bottom of above-mentioned bunchy or on sinker, tied a well rope rope 3.
Considering the identification reef placement position under water of laying eggs, is again that a buoy 4 is arranged on well rope rope 3, swims on the W of sea as sign.
As embodiment, select side shoot and the branch ligation bunchy of Chinese tamarisk, 4～5 centimetres of single bundle base diameter, be made into " branch " shape adherance, base portion is attached with the length of side 10～20cm, heavily about 2～4 kilograms halfpace shape cement sinker, then it is tied on the well rope rope of being made by 10 millimeters polyethylene ropes of diameter by the spacing of bundle with 1～2 meter of bundle.For ease of operation, restrict long 120～150 meters for every, each test is made all kinds of adherances 30～60 ropes year altogether and is not waited.The seabed is put in the adherance following current of making successively, and two ends are fixed with pier stone or anchoring, and the water surface indicates with buoy.About 100 meters of longitudinal pitch, about 500 meters of horizontal spacing.Another part then configures sinker, and single bundle directly looses and throws in the sea area.The test sea area is chosen in Rizhao City Lan Shan coastal waters, and this marine site is positioned at the golden cuttlefish spawning ground, 15～20 meters of the depth of waters, and at the bottom of substrate was husky mud, water quality was pure and fresh, the golden cuttlefish propagation marine site that current are unimpeded.In the period of calendar year 2001～2003 years 3, Chinese tamarisk and each 10,000 bundle of chrysanthemum punt-pole, cuttlefish cage 2000 cages are made in this test altogether.To lay eggs reef and cuttlefish cage is applied to pre-Dinghai District, goes to sea every 5～10 days afterwards and once observes and manage, and make outcome record.The result shows, the golden cuttlefish of making as adherance with the Chinese tamarisk branch average adhesive rate of reef of laying eggs can reach 74.0%, and the chrysanthemum punt-pole takes second place.
