In recent years, due to the unreasonable exploitation of the sea area of ??shallow water shellfish raft culture suffered a hit, and the urgent need to determine from the theory and the practice of farming capacity and breeding patterns. The the papers measured with laboratory experiments and sea scene breeding method, research of sediment feeders stichopus shellfish sediments ingestion, absorption and excretion; same time, relatively shallow sea culture systems thorn involved in shellfish polyculture different modes The effect of the growth of the sea cucumber, identified a new breeding patterns and sea cucumber farming capacity. The experimental part of the indoor sea cucumber aquaculture: April 2001 to June, using the same specifications as the indoor tank Institute of Oceanology, Chinese Academy of Sciences, Qingdao, breeding different specifications of the sea cucumber, the use of the natural water temperature, feeding scallops biological sediments. Experiment each tank temperature, light, salinity and water changes consistent, periodic determination of sea cucumber feeding rate, absorption rate, oxygen consumption rate and ammonia excretion rate eco-physiological indicators. The experimental results are as follows: a feeding shellfish biological sediments, of different specifications stichopus weight increase is more obvious, the average weight gain in the two months are 1.5 times more. In the course of the experiment, the average water temperature 13.2 ~ 22.3 ° C, different specifications stichopus on shellfish sediments average feeding rate (g / gh) followed by a large (O.00324), in (0.00648) (0.00959). Visible to shellfish sediments as bait, sea cucumber feeding rate, which has an important role in the growth of the sea cucumber can be used as indoor and marine areas breeding and proliferation stichopus of effective ways and means. The 2 experiment, different specifications stichopus on the average absorption rate of shellfish sediments according to (7.32%) (13.49%) (17.61%). Among them, the average temperature of 15.13 ℃, the large size of sea cucumber feeding rate to 15.32%; When the temperature rises to 17.36 ℃, medium and small-two specifications stichopus of absorption rate was the highest, followed by (20.35% ), small (23.00%). Sea cucumber on the absorption and utilization of organic matter in the sediments, reduce the organic content of the bottom, thus inhibiting the accumulation of harmful substances and produce water. 3 stichopus respiratory metabolism oxygen consumption rate during the experiment the sea cucumber average weight and absolute oxygen consumption rate (g / indh) can be expressed as R = aW ~ b, the regression equation a value range is 0.020 to 0.211, the average for 0.116, the B value of 0.441 to 1.069, the average value of 0.755, the R to 2 value of 0.9376 to 0.9986. Relative oxygen consumption rate of the sea cucumber with the water temperature rises and rises, the temperature change on the relatively small size of sea cucumber oxygen consumption rate was less affected, while large, the specifications in stichopus relative oxygen consumption rate affect larger when The average water temperature rose to 20.2 ° C, the specifications stichopus relative oxygen consumption rate reaches its maximum. 4 stichopus excrete metabolic ammonia excretion rates, the average weight of the sea cucumber with absolute ammonia excretion rate in the experimental temperature can be expressed as A = aW to b, a, b average is 5.794 and 0.393. The correlation coefficient of the regression equation in the 0.9664 to 0.9968. Relative ammonia excretion rate of sea cucumber with rising water temperature increased, the different specifications stichopus ammonia excretion rate by the effects of temperature changes, when the average water temperature of 17.36 ℃, relative row in the specification of sea cucumber ammonia excretion rate each contributed to the largest, are 2.417pg/gh and 4.863pg/gh. 5 aestivation in specifications stichopus into their feeding rate, absorption rate, oxygen consumption rate and ammonia excretion rate made a significant change in general, but for the small size of sea cucumber its growth and metabolic activity aestivation impact than small, and some do not even aestivation. Sea Senate shellfish polyculture experimental part: bay scallop at 200 Lu months to April 2002, in Yantai Sishili Wan was stabbed to participate as well as the thorn in Pacific Vitex the roundworm different series mode diversified system of farming, Determination of sea environment growth condition and sea cucumber in the different modes, compare and determine the best breeding patterns and sea cucumber stocking density. Experimental results show that: the sea diverse culture ecosystems, bay scallops and sea cucumber of different polyculture model of sea cucumber instantaneous growth rate of the size of the order of: tape (AS) mode, two grid (BS) mode and polyculture (CS) mode, where reasonable growth mode: AS mode in the AS3 (instantaneous growth rate is 0.365, the sea cucumber stocking density of 6); BS (BS mode instantaneous growth rate is 0.294 stocking density The 4,8 cell 2); CSZ CS mode (instantaneous growth rate is 0.266, the stocking density of 2). 7 Pacific Vitex Burma and sea cucumber polyculture mode stichopus the instantaneous growth rate order: tape (AM) mode, two cells (BM) mode, polyculture (CM) mode, at this time, a reasonable growth mode: AM AMI mode (instantaneous growth rate of 0225, the stocking density of 2); the BM mode BMI (instantaneous growth rate is 0.146, the stocking density of 4,8 grid 2 each); the CM modes (instantaneous growth rate is 0.103, a stocking density). 8 Tony parameters diversified farming mode stichopus all grow well, to the end of the trial, Tony parameter has a significant growth achieved the desired effect. Sea cucumber water body \In addition, this study initially identified, the shallow sea shell parameters farming model stichopus the stocking density 2.0 / grid more reasonable.
