We estimated the growth of Jack mackerel (Trachurus murphyi) using increments daily growth, otolith weight and annual ring reading in sagittal otoliths. The micro-increments were used to fit density radius (n = 4481) then estimate age individual days. parameters von Bertalannfy equation were: maximum theoretical fork length, FL∞ 75 cm; coefficient, K 0.16 year-1; at which fish length is zero, t...

Length composition data of narrow-barred Spanish mackerel, Scomberomorus commerson (Lacepede 1800), landed between April 2002 to March 2004, were monthly used to estimate the growth, mortality and exploitation parameters of the stock. Maximum fork length and weight were 170 cm and 38 kg, respectively. Nonlinear least square fitting provided a complete set of von Bertalanffy growth estimates: L¥...

difficult to maintain desired water tables after normal rainfalls. Sugarcane (interspecific hybrids of Saccharum spp.) in the EverA second factor that has complicated EAA drainage glades Agricultural Area (EAA) in Florida is frequently subjected to periods of higher-than-desired water levels. This study was conis the need to decrease P discharge to the Everglades. ducted to evaluate yields of n...

Phrenic nerve stimulation (PNS) applied at end-expiration allows the investigation of passive upper airway (UA) dynamic during wakefulness. Assuming that phasic UA dilating/stabilizing forces should modify the UA properties when twitches are applied during inspiration, we compared the UA dynamic responses to expiratory and inspiratory twitches (2 s and 200 ms after expiratory and inspiratory on...
