Stocking density is one of the crucial factors affecting the growth and survival of Pacific white shrimp. A suitable density is critical in culturing shrimp, balancing the production as quantity and marketing as quality. Therefore, the present study optimized stocking density for pacific white shrimp reared in the pond ecosystem in Pakistan. The initial weight of postlarvae was (0.003±0.001 grams), and were stocked in 3 stocking densities (Treatment 1- 133.3 PL/m2, Treatment 2- 300 PL/m2, and Treatment 3- 466.6PL/m2) for 114 days. The water quality parameters ranged between (29.3-30.2° C), (5.1-5.5 mg/L), (5.8-7.3), (24.16-16.44 ppt.), (118-120 mg/L), (0.29-0.41 mg/L), (0.97-1.51mg/L), (0.08-0.09 mg/L), (0.02-0.12 mg/L) and (560.66-610 mg/L) for temperature, DO, pH, salinity, alkalinity, phosphate, nitrate, nitrite, ammonium nitrogen and TSS, respectively. Treatment 1 had the highest final weight (24.30±0.90 g), final length (15.8±0.30 cm), average daily gain (0.21g /day), weight gain (24.29 g) and Viscerosomatic index (4.6 g), which was significantly different compared to treatment 2 and treatment 3 (p<0.05). SGR did not differ significantly (p>0.05) between treatment 1 (7.64 % /day) and treatment 2 (7.63% /day) but was significantly higher than treatment 3 (7.10 %/ day). The Hepatosomatic index and Fulton’s condition factor were not significantly varied among the treatments. Treatment 1 had the best FCR (1.11) compared to the other treatments. The survival rate of shrimp significantly varied among these treatments (p<0.05) and treatment 1 had the highest survival rate (90.6%), followed by treatment 2 (82.20%) and treatment 3 (75.38%). Moreover, polynomial regression showed that 133.3 PL/m2 to 240 PL/m2 is an excellent stocking density for L. vannamei. Furthermore, the stoking density from 240 PL/m2 to 460 PL/m2 decreased the growth and survival rate. The present study concluded that the stocking density of L. vannamei at 250-300 PL/m2) can achieve the best growth and survival rate.

Ranked by citation count — the same ordering the engine uses when summing log1p(Cq) over citers.
DataRank blends this paper's own citation count with the influence of the papers that cite it. Here, roughly 62% comes from its base citations and 38% from the citation network (1 citing paper contributed measurable signal).
Citers are pulled from OpenAlex sorted by cited_by_count:descand capped per paper, so when the cap binds we keep the highest-signal references and the score is reproducible across reruns.
