Evaluation of Fish Stocking in Southeastern South Dakota Ponds
A mail survey was sent to owners of 220 ponds which had received hatchery fish. Based on 187 pond owner responses, at most 45 (24%) of the ponds still contained the fishes stocked. Pond dryness and/or winterkill attributed to the failure of 121 (65%) of the ponds. A subsequent field survey of 30 …

Evaluation of Largemouth Bass and Bluegill Stocking Strategies in South Dakota Ponds
Three fish-stocking methods were evaluated to determine the effects of stocking density and chronology on largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus) survival, growth, and reproductive success during 1983-1985. Two densities of split-stocking largemouth bass with …

Optimal consignment stocking policies for a supply chain under different system constraints
The research aims are to enable the decision maker of an integrated vendor-buyer system under Consignment Stock (CS) policy to make the optimal/sub-optimal production/replenishment decisions when some general and realistic critical factors are considered. In the system, the vendor produces one …

Purpose-orientated stocking of procedure trolleys saves time in busy Emergency Centres
… and drawer opening. Conclusion In our setting, stocking procedure trolleys in a purpose-orientated manner has the potential to improve efficiency by reducing time spent on procedure preparation.

A comparison of runoff quantity and quality among three cattle stocking treatments
… of runoff quantity and quality from three cattle stocking treatments applied to pastureland in southwestern Virginia indicate the need for further research to determine treatment effects. Three cattle stocking treatments (1) Continuous, 2) Rotational, and 3) Mob) were applied to three pastures at …

Impacts of Stocking Herbivorous Fishes for Aquatic Macophyte Removal Upon South Dakota Ponds
… stocked bluegills was low as a result of small stocking length. Mean survival rate for age-I largemouth bass was 38% for eight ponds. Mean growth and mean Wr for age-I largemouth bass was 160 nm and 119 g, respectively. Abundance of age-0 largemouth bass appeared to be influenced greater by the …

Decision models for fast-fashion supply and stocking problems in internet fulfillment warehouses
… explosive storage policy. Breaking the single stocking location tradition, in an IFW small batches of the same stock keeping unit (SKU) are dispersed across the warehouse. Order fulfillment time performance is then closely related to the storage location decision, that is, for every incoming …

Comparisons of tilapia seed production under various broodstock densities and fry stocking densities
… fry female-1 month-I) (p>0.05). The effects of stocking density on growth and survival were evaluated by stocking 14-16 day old artificially incubated fry (25.5 ± .32 mg, 12.1 ± .04 mm), into 150 liter troughs at three densities (3, 6, and 12 fry liter-I) under green water conditions for 30 …

Mob stocking effects on herbage nutritive value, herbage accumulation, and plant species composition
Mob stocking is a variation of rotational stocking known for restricting a large number of animals to a small area before being moved to new grass after a few hours. This method allows a long (90-day) recovery period but was hypothesized to diminish the nutritional value of herbage relative to …

The effects of stocking density and housing on feed efficiency and growth performance of broiler chickens
… The research aimed at determining the effects of stocking density and housing type on broiler performance, welfare, and economic implications. High stocking density is a strategy used by broiler farmers to maximize floor space, but it can have adverse effects on chickens, including lower growth …

Effect of stocking density at the feeding rack and social rank on the behaviour of Icelandic heifers
Overstocking of Icelandic dairy heifers with regard to the animal feeding place ratio has become more common during the last years. Rather little is known about the behavioural consequences for heifers of this management procedure, which imposes a competitive situation on the animals. The aim of …

Influence of Food Web Structure and Environmental Conditions on Walleye Stocking Success in Two South Dakota Impoundments
… North America has resulted in increased stocking efforts and management of Walleye populations. Despite annual stockings, Walleye abundance in Mina Lake, South Dakota has remained low. Previous research at Mina Lake has shown increased trophic state, large proportions of benthic …

The effects of dietary forage, social hierarchy, and stocking density on stress in lactating cows during relocation
… effects of forage fiber, social hierarchy, and stocking density on stress in lactating cows during relocation to new dairy facilities. In experiment one, 23 lactating cows were fed a basal ration, or the basal ration plus grass or alfalfa hay at 10% of DM offered from 3 wk pre-move to 9 wk …
