“…This means that a different diet did not change the endocrinological performances in males that are necessary for maturation of spermatozoa (Alavi and Cosson 2006). However, a highly significant effect of diets on sperm velocity can be related to the ATP content, which is a key factor determining sperm velocity (Perchec Poupard et al 1998). Asturiano et al (2001) also observed no significant effect of PUFA on quality or motility of sperm between groups or on fertilization rates.…”

Sperm quality of Barbus barbus L. was compared among the three following dietary regimes: Group A, fed 100% commercial diet (Karpico containing 33% crude protein and 6% fat), Group B, fed 78% commercial diet and 22% frozen chironomid (Chironomus plumosus) larvae, and Group C, fed 56% commercial diet and 44% frozen chironomid larvae. Concentrations of polyunsaturated fatty acids (PUFAs) in Group A, B, and C were 39.1, 42.0, and 44.6, respectively, as a percentage of total fatty acids. Sperm morphology, volume, concentration and motility, total number of spermatozoa, and osmolality of the seminal plasma were compared during the spawning season. Dietary regime did not influence sperm volume, concentration, or total number of spermatozoa, osmolality of seminal plasma, or the percentage of motile sperm, but significantly affected sperm morphology (except for anterior and posterior parts of the midpiece) and sperm velocity (P < 0.05). Groups B and C showed similar sperm characteristics during the spawning season compared to Group A. Almost all parameters changed either among or within groups during the spawning season, suggesting differences in terms of the optimal time for sperm collection. The best time for sperm collection was March for Group A, but April for Groups B and C, when the osmolality of the seminal plasma measured 289 mOsmol kg(-1) and sperm motility was maximal. Spermatogenesis, hydration, and cell decomposition were confirmed as the three major parameters controlling sperm characteristics during the spawning season. The possible correlation between sperm morphology and motility requires further study.

“…Os primeiros oócitos foram desprezados para evitar possível contaminação por urina ou fezes (BROOKS; TYLER; SUMPTER, 1997), sendo o restante colocados em placa de Petri. A coleta dos gametas masculinos foi idêntica às fêmeas, sendo a primeira gota de sêmen desprezada para evitar possível contaminação (POUPARD et al, 1998) e o restante foi coletado em um tubo de ensaio.…”

de taxa de fertilização, unidade térmica acumulada para início e término da eclosão, taxa de eclosão, desenvolvimento embrionário e percentual de larvas normais. Os resultados foram submetidos a análise de variância e a análise de regressão a um nível de 5% de probabilidade. Os níveis de amônia presentes na água não interferiram sobre os parâmetros avaliados (p>0,05), exceto quanto ao desenvolvimento embrionário inicial, onde os embriões expostos aos maiores níveis de contaminação por amônia apresentaram maiores (p<0,05) taxas de fechamento do blastóporo. De modo geral, a presença de até 0,84mg de amônia total.L de água -1 acelera o desenvolvimento inicial embrionário mas não interferem nas taxas de fertilização e eclosão. Palavras-chave: Amônia, embrião, larvas, peixe, poluente AbstractThe aim study it had as objective to evaluate the effect of different ammonia levels, on the parameters of sperm motility, the artificial fertilization and the early development of jundia (Rhamdia quelen; Siluriformes, Heptapteridae). The semen was activated using the dilution of 1:70 (semen:water) and evaluated by the CASA method. It was considered as treatment water contending 0,06; 0,28; 0,50; 0,77

“…The research done on carp semen showed that the addition of even a low volume of urine causes a significant decrease in sperm motility parameters (Poupard et al, 1998). A small addition of urine also causes lower freezing efficiency (i.e., a lower percentage of motile spermatozoa obtained after thawing).…”
