چکیده

In Penaeus indicus neuroendocrine organs plays an important role in the growth and reproduction. In Penaeus indicus four different types of neurosecretory cells such as A cell, B cell, C cell, D cell were identified. The Eyestalk of Penaeus indicus shows many neurosecretory cells, but the Brain and Thoracic ganglion shows only few neurosecretory cells. After the unilateral Eyestalk ablation the Brain and Thoracic ganglion has many neurosecretory cells. The neuroendocrine glands are stimulatory and inhibitory in function. Brain , Thoracic ganglion are stimulatory principles of growth and reproduction. But the neurosecretory cells in the Eyestalks are inhibitory influence of these function.

In this study, we investigated the effects of different levels of dietary nucleotide (0, 0.2, 0.4 and 0.6%) on immunity parameters and total protein plasma of Litopenaeus vannamei female brood stock in four experimental treatments (three replication per treatment) during the maturation period and after eye stalk ablation. Total soluble proteins and immunity parameters such as total haemocyte co...

Effects of bilateral eyestalk ablation on gonadal maturity, moulting and biochemical changes in the hemolymph of female Potamonpersicum crabs (Decapoda, Brachyura, Potamidae)

Adult female crabs (Potamonpersicum; n=65) were collected from the Jajrood River in the east of Tehran, Iran. Both eyestalks were removed in crabs that weighed 27.6 ± 2.1 g. Changes in the levels of glucose and protein titers in the hemolymph, the number of hemocytes, gonadal and hepatic indices, body weight and carapace length were determined. The level of glucose in the hemolymph was signific...

Effect of unilateral and bilateral eyestalk ablation in Litopenaeus vannamei male and female on several metabolic and immunologic variables

Eyestalk ablation is the most common procedure to induce gonadic maturation in commercial hatcheries of penaeid shrimp. In addition to reproduction, other physiological and metabolic processes are affected by removal of the X-organ sinus gland complex located in the eyestalk. In this study, the effect of unilateral and bilateral eyestalk ablation on the concentration of several hemolymph metabo...

Ovarian maturation and spawning in the tiger shrimp, Penaeus monodon by serotonin and dopamine injection

The effect of serotonin (5-hydroxytryptamine, 5-HT) injection on the ovarian maturation and spawning of wild Penaeus monodon was investigated. The neurotransmitter was evaluated at 20 μg g-1 body weight (b.w) and 50 μg g-1 (b.w) applied at day 2, 12 and 22. The effect was compared against a control group, which received the injection of the sterile vehicle solution (NaCl 0.85%), and an unilater...
