Digging shrimp Neaxius vivesi (Bouvier 1895) were collected with harpoon in February, May and August of 1986 in Bahia de Los Angeles, B.C., Mexico (28 degrees 53' N; 113 degrees 34' W).Burrows were randomly sampled with a 1x1 m quadrat.39 speciemens were captured, 19 in February, 12 in May and 8 in August;.54% were female, but males were better represented in February and August.Length and weight means were 91.6 mm and 14.6 g.February females and May gmales had the highest means, and maximun individual values were registered for females in February and minimum for females in August.The weight-size, /correlation (both sexes) was of r > 0.80 (t > 0.05).A clear alometry was observed.Density highest could reach an average of 9 burrows/m2.Each burrow had one male and one female, which alternated in feeding. |
