专利汇可以提供Method for growing edible aquatic animals on a large scale专利检索,专利查询,专利分析的服务。并且A continuous and large-scale method for growing batches of shrimp or other aquatic animal from an initial average unit weight to a desired average unit weight. As exemplified by the growing of shrimp, each batch of shrimp is grown to increasingly larger unit weights by sequential transfer through a series of continuous-flow, above-ambient-temperature ponds of increasingly larger batch dwell volume. The ponds are fed by a stream of water which is at above-ambient temperature by virtue of being derived at least in part from effluent water coolant from an industrial facility. A batch of shrimp to be grown is transferred into each of the ponds for approximately equal growth periods. In a preferred form of the method, the dwell volumes of the ponds are sized so that approximately the same animal weight density prevails in each pond at the end of the growth period associated with that pond.,下面是Method for growing edible aquatic animals on a large scale专利的具体信息内容。

1. In the growing of the members of a batch of a selected species of aquatic animal from an initial average unit weight w to a desired average unit weight wn, said species being confined in a body of water maintained under conditions meeting the biological growth requirements thereof, the improvement comprising: a. on a growth curve for said species selecting first and second points corresponding respectively to said initial average unit weight wand said desired average unit weight wn; b. subdividing that part of said curve between said points into periods of equal time t to determine the unit weights w1... wn attained by the ends of said periods; c. providing a series of above-ambient-temperature, continuousflow ponds p1... pn whose respective dwell volumes for said species increase in substantially the same proportion as said weights w1... wn, said ponds being fed by a stream of water which is at above-ambient temperature by virtue of being derived at least in part from effluent coolant water at aboveambient temperature; d. introducing said batch into the smallest-dwell-volume pond p1 of said series of ponds and maintaining it therein for said time to grow the same from said initial weight w to said weight w1; e. sequentially transferring the batch so grown into each of the remaining ponds p2... pn for said time t to respectively increase the average unit weight of said batch to the values w2... wn; and f. recovering said batch from the largest-dwell-volume pond pn of said series.
2. The method of claim 1 wherein said stream of water is salt water.
3. The method of claim 1 wherein said stream is fresh water.
4. The method of claim 1 wherein said stream is formed by blending effluent coolant water at above-ambient temperature with water at substantially ambient temperature.
5. The method of claim 1 wherein said effluent coolant water is derived from a desalination plant.
6. The method of claim 1 wherein said ponds are connected in parallel with respect to said stream.
7. The method of claim 1 wherein said series of ponds is formed by directing said stream of water through a raceway partitioned by a plurality of transversely disposed screenlike members.
8. The method of claim 7 wherein said members are movable along the major axis of said raceway.
