RBT60712022-05-30T19:06:49Z Comparison of some reproductive characteristics of farmed and wild white shrimp males Litopenaeus vannamei (Decapoda: Penaeidae) Comparison of some reproductive characteristics of farmed and wild white shrimp males Litopenaeus vannamei (Decapoda: Penaeidae) Rendón Rodríguez, Sergio Macías Regalado, Emilio Antonio Calderón Pérez, José Núñez Pastén, Arturo Solís Ibarra, Rafael Litopenaeus vannamei reproducción machos reproduction males We rated some reproductive characteristics of white shrimp Litopenaeus vannamei (Boone, 1931) males using 46 farmed individuals (weighing 21.42±0.56 g) and 40 wild individuals (weighing 36.10±0.72 g). In farmed shrimps, spermatophore mean weight was 8.94±0.51 mg; total mean sperm count was 3.90±0.27 x 106 in each spermatophore; and mean percentage of normal sperm was 86.9±0.37 %. In wild individuals, the respective values were 30.68±2.32 mg; 6.22±1.09 x 106; and 62.1±3.56 %. In both groups, the differences between right and left spermatophore were not significant (p < 0.01). There were significant differences in spermatophore weight and percentage of normal sperm between farmed and wild shrimps; sperm counts differences, however, were not significant (p < 0.01). The relationship between spermatophore weight (Ws) and individual weight (Wo) was Ws (mg)=1.23 (Wo)-17.34 (r2=0.89), in farmed shrimps; and Ws (mg)=2.57 (Wo)-60.04 (r2=0.64), in wild ones. In cultivated organisms, the relationship between sperm counts (Cs) and individual weight (Wo) was Cs (x 10^6)=1.13*10-4* (Wo) 3.361 (r2= 0.85); and versus spermatophores weight was Cs (x 10^6)=0.439* (Ws) 0.984 (r2= 0.90). In wild organisms, there was no correlation. The proportion of normal sperm ranged from 79.8 to 95.2 % (86.9±0.37 %) and from 14.0 to 91.5 % (62.1±2.52 %), in farmed and wild shrimps, respectively. The most frequent abnormalities in both farm and wild animals were sperm without spike (49.3 % and 76.6 %, respectively) and irregular shape (35.8 % and 17.7 %). The less frequent occurrences were those of bent (10.2 % and 4.29 %) and double spike (4.7 % and 1.41 %).
