“…which agreed with many studies but are not successive(Chung et al 2013;Kim et al 2013). Lacking periodicity and the year-round P. textile reproduction is a common phenomenon in tropics and subtropics regions (Ceuta and Boehs 2012;Kandeel et al 2013) and is probably attributed to the dominance of warm water most of the year.…”

Understanding the reproductive biology of aquatic biota is essential for better management and sustainability of coastal ecosystems and aquaculture development. The bivalve Paphia textile (Gmelin 1971) also known as Paratapes textilis, has an economic value in Indo-Pacific waters and the Red Sea. P. textile suffers from extensive fishing and exploitation. The current work aims to study the reproductive cycle of P. textile for the first time in the Egyptian waters of the Red Sea. Samples were collected monthly from two saline lakes at the Suze Gulf from December 2019 to November 2020. As part of the comprehensive research study, sex ratio, condition index, sexuality, histological analysis of the gonad maturity stages, shell size at maturity, and gonad index, were used to investigate the reproductive cycle. The results revealed that the sex ratio was male biased possibly due to anthropogenic stressors. Paphia textile has dioecious sexuality and hermaphroditism is lacking. The condition index in winter and spring indicates periods dominated by mature individuals. Five reproductive maturity stages were assigned for P. textile males and females. The prevailing warm water year-round could be the reason behind the lack of successive stages of gonad maturity and periodicity. The study indicates that gonad development is a function of temperature, salinity, and chlorophyll. The Paphia textile shell sizes at which 50% of the population reached maturity ranged between 28 mm and 34 mm for females and males, respectively. A gonad index indicates the ripe stages. Study findings suggest the most suitable temperature for aquaculture spawning is between 20 ◦C and 30 ◦C in subtropical waters, and fishing should be prohibited at sizes less than 28.60 mm in general for males and females for better management and sustainability of this aquatic resource.

Simping (P. placenta) is a coastal resource found in shallow water with a muddy substrate. Simping widely used as a source of food and as raw material for the decoration. Utilization of simping until now has not yet focused on recruitment, reproductive aspect. This information is important as a basis data for determining the size of the simping catch. This study aimed to find out about of reproduction aspect, determining sex ratio the size of the catch simping. This research was conduct for three months at 3 locations. The number of samples in the analysis is 36 species to determine sex ratio and gonad maturity. Sex ratio indifferent from male and female, but based on the time sex ratio of simping significant, both male and female. The length size of gonads shellfish matures form 5.50 cm and 5.85 cm at 2 TKG conditions. Length of simping mature from 6.08 cm, 6.24 cm, 6.45 cm and 7.11 cm dominant at TKG mature stage 3, and 8.61 cm dominant at 4 TKG conditions. Sex ratio reaches 6 cm shell length and not significant between males and females (M: F=1;1). It is concluded that the level of maturity of gonads increases with increasing of simping size.

Background Most aquatic biota's reproductive biology and life cycle are essential to the sustainable management and development of coastal ecosystems and aquaculture. The bivalve Paphia textile (Gmelin 1791), also known as Paratapes textilis, has an economic value in Indo-Pacific waters, including the Red Sea and the Suez Canal lakes, the Egyptian coasts. However, P. textile suffers from extensive fishing and exploitation. Aim The present work aims to study the Paphia textile's reproductive cycle on the Egyptian coasts of the Red Sea for the first time. It helps to manage and develop the coastal ecosystems and aquaculture. Methodology Samples were collected monthly from two saline lakes in the Suez Gulf from December 2019 to November 2020. As part of the comprehensive research study, sex ratio, condition index, sexuality, histological analysis of gonads, shell size, and gonad index were used to investigate the reproductive cycle. Results The results reveal a male-biased sex ratio, possibly due to anthropogenic stressors. The Paphia textile is dioecious. No hermaphrodite cases were observed in the studied specimens. The condition index in winter and spring indicates periods dominated by mature individuals. Five reproductive maturity stages were assigned for both P. textile males and females. Due to the simultaneous development of several developmental stages monthly throughout the sampling year, warm water may be responsible for non-sequential gametogenic cycles. As measured environmental parameters correlate with maturity stages, temperature, salinity, and chlorophyll a play important role in gonad growth. The size at first sexual maturity at which 50% of the Paphia textile population reached maturity ranged from 28.60 to 31.50 mm for females, and between 31.70 and 34.10 mm for males. As the gonad index increases during the ripe stages, this index decreases during the resting, spawning, and spent phases. Conclusions The findings suggest the most suitable temperature for aquaculture spawning is between 20 °C and 30 °C in subtropical waters. Fishing should generally be prohibited at sizes less than 28.60 mm for better management and sustainability of this valuable aquatic resource on the Egyptian coasts of the Red Sea.
