Floc contribution on spawning performance of blue shrimp Litopenaeus stylirostris
Provedor de dados: 5
Autores: Emerenciano, Mauricio; Cuzon, Gerard; Goguenheim, Jean; Gaxiola, Gabriela.
The floc system has been successfully applied for shrimp grow-out, but little is known about floc contribution on reproductive performance. In a 30-day trial, spawning performance of broodstock was evaluated in floc and earthen ponds. Floc spawners achieved better results (P &lt; 0.05) compared with pond spawners in terms of number of spawns per ablated female (2.9 vs. 1.3), spawns per spawning female (3.6 vs. 2.4) and number of consecutive maturation (average of 3.6 times compared with 2.5 times in ponds females). Latency period was lower for floc spawners (7.4 days) than pond spawners (10.7 days) (P &lt; 0.05). The percentage of females that spawned at least once were higher in floc (77.1%) when compared with pond spawners (53.8%) (P &lt; 0.05). Number...

A 30-day trial was performed to evaluate the reproductive performance of wild and 2nd generation domesticated Farfantepenaeus duorarum broodstock. Changes in biochemical composition and fatty acids (FA) profile in the 1st and 4th spawn order females were used as indicators of nutritional condition. Wild population of F. duorarum presented significantly better reproductive outcomes as compared to domesticated ones. Wild spawners achieved significantly higher number of eggs per spawn, number of egg per spawn per g of spawner's body weight and number of nauplii per spawn (P&lt;0.05). Latency period was significantly shorter (P&lt;0.05) for wild than for domesticated females (11 vs 17 days). Wild spawners also presented less mortality (6 vs 12%), higher number...
