Some Aspects of Reproductive Biology of Blue Swimming Crab (Portunus pelagicus (Linnaeus, 1758)) Under Laboratory Conditions

Abstract: This study was carried out to observe and describe sexual dimorphism, reproductive system, macroscopic and histological gonad development and Gonado Somatic Index (GSI) of blue swimming crab (P. pelagicus) during post-spawning, spent spawner and berried female under laboratory conditions. The general sex dimorphism and reproductive system of male and female blue swimming crab were observed similar to be most other decapods crustaceans. The pubertal molt, the abdomen and gonopores of female show changes that ar… Show more

“…A total of five units from each tank were placed in a plastic box (45.5 × 32.5 × 16.5 cm) at a maximum density of one crab per box. The tanks were provided with a sand substrate layer approximately 15 cm thick with adequate aeration 2, 6, 7 . The crabs were maintained a monitored water depth of 25–30 cm with salinity of 29–32 parts per thousand (ppt), pH of 7.26 to 8.00, temperature of 26–28°C, and DO of 6.15–7.45 ppm.…”

“…The female crab samples were collected from the coastal region of Padang (100° 22'12" BT, 1° 0' 54" LS dan 100° 25'58,8" BT, 1° 4' 40,8" LS), West Sumatra, and the crabs were placed randomly in four concrete tanks (200 cm × 100 cm × 100 cm), each divided into five units, i.e., plastic boxes (45.5 cm × 32.5 cm × 16.5 cm), where the crabs were held at a maximum density of one crab per box. Tanks were provided with approximately a 15-cm-thick layer of sand for substrate and with adequate aeration 2,7,8,[26][27][28] . The crabs were maintained in monitored water with a water depth of 25 to 30 cm, salinity of 30 to 32 ppt, pH 7.77 to 7.96, temperature 26 to 27°C, and dissolved oxygen (DO) 7.00 to 7.30 ppm.…”

“…Then, two morphometric characteristics of the crab, carapace width (CW) and body weight (BW) were measured. Subsequently, the crabs were dissected by using dissecting tools and the stages of ovarian maturation were determined based on the study by Efrizal et al, (2015) which divided it in five stages; immature stage (Stage I), early maturing (Stage II), advance maturing (Stage III), mature (Stage IV) and spent stage (Stage V). Stage differentiation was done through histological color and structure.…”
