Abstract:

Detailed radial measurements of wood properties at four heights (0, 1.4, 5, and 20 m) were taken from 24-year-old Pinus radiata D. Don growing at four final crop stockings (200, 350, 500, and 1100 stems·ha–1). Using these measurements, the objectives of the study were to examine pith-to-bark trends at several heights to (i) determine how stocking influenced modulus of elasticity (MoE), wood density, and microfibril angle (MFA), (ii) quantify the relations among these properties and age at different stocking levels, and (iii) develop a graphical model for MoE across the stocking range.

Abstract:

ABSTRACT The increasing trend of vaname shrimp cultivation production encourages farmers to increase their cultivation production. The success of vaname shrimp cultivation can be seen from the ability to measure the capacity of shrimp biomass in maintenance activities and stocking density patterns based on the maximum capacity of the pond in each plot. The purpose of this study was to analyze vaname shrimp cultivation activities for a period of 2 years (2023-2024) in intensive system ponds based on different stocking density patterns at 140 shrimp/m2 and 190 shrimp/m2.

Abstract Stand Density Index (SDI) equations were developed and presented for upland hardwoods in southern Ohio. The relationship between SDI and stocking percent from upland hardwood stocking charts were developed, and a diagram displaying this relationship is presented. Critical stand density boundaries equivalent to stocking percent on stocking charts were defined: (1) the C-level of stocking (SDI < 125), (2) the B-level of stocking (125 ≤ SDI < 215), and (3) the A-level of stocking (215 ≤ SDI < 250).

Abstract Stocking density is one aspect of cultivation that needs to be known because it affects the growth rate and survival rate that determines the level of production. High stocking density will result in competition in getting feed and space, resulting in growth variations.

These densities were combined with static water (non-exercised group) or moderate-speed water (exercised group). Chronic stress was observed in HD, and plasma cortisol and glucose increased with the stocking densities.
