“…In crustaceans, the GSI is a gross quantitative indicator of gonad condition and represents the simplest way to measure changes (Rodriguez-Gonzalez et al, 2006). The mean values of GSI calculated here were significantly different between the maturity stages and this result validates the macroscopic stages table created to characterise the gonad maturity of P. henslowii females.…”

Polybius henslowii Leach, 1820, a Portunid crab distributed from the British Isles to Morocco and the Mediterranean Sea is caught in high densities by many types of fishing gear and frequently thrown back to the sea. Along the northern coast of Portugal, P. henslowii is an important species discarded in beam trawl fishery. There are no quantitative estimations of discards and very little is known about its biology, information that is needed to value this species. The present work was conducted from March 2007 to December 2010 in order to improve the current knowledge of the reproductive biology of P. henslowii. By-catches were registered aboard commercial vessels that volunteered to participate in the study. In that period P. henslowii represented 57.3% of the total catch and was present in all hauls analysed. The target species, Palaemon serratus (Pennant, 1777), represented 1.2% of the total catch, showing the low selectivity of the fishing gear and the need for suppression of this gear to catch this shrimp species. Differences in size between sexes were found, with males being larger and heavier than females. Mature females occurred mainly in autumn and the carapace width at which 50% of the females reach maturity was estimated to be 37.8 mm, which could be set as the minimum landing size of this potential exploitable resource. A macroscopic ovarian maturity stages classification was proposed, allowing a rapid field assessment of female sexual maturity. This study fills a gap in the knowledge of a very important species discarded in beam trawl fishery that may be basis of further work.

“…La presencia de ovogonias, ovocitos previtelogénicos y vitelogénicos junto con ovocitos maduros en el estado IV del desarrollo gonadal de C. caementarius, sugiere que al igual que en Cherax quadricarinatus, a medida que avanza el proceso de maduración algunos ovocitos crecen rápidamente mientras que otros permanecen inactivos (Rodríguez-González et al, 2006).

RESUMEN.La extracción indiscriminada y alteraciones del medio natural, han puesto en peligro de extinción al único Palaemónido dulceacuícola de interés comercial, presente en aguas continentales chilenas. Aun cuando esta situación, ha despertado el interés en estudios que permitan su reproducción controlada en cautiverio, actualmente es escaso el conocimiento acerca de aspectos reproductivos básicos de esta especie. Dada su importancia, este trabajo describe y caracteriza el proceso completo de maduración gonadal en hembras de Cryphiops caementarius, en base a cambios en la morfología externa e interna del ovario. Hembras adultas extraídas del río Limarí, fueron disectadas y sus ovarios removidos y preparados para análisis histológicos. Tejido fibromuscular divide el tejido gonadal de cada lóbulo en sacos ováricos de forma semicónica (conos de maduración), al interior del los cuales se encuentran ovocitos en diferentes estados de desarrollo de acuerdo a observaciones microscópicas de tamaño, morfología y tinción con H-E, las células reproductoras femeninas se clasificaron en seis tipos, ovogonias (Ov), ovocitos previtelogénicos tempranos (O1), ovocitos previtelogénicos tardíos (O2), ovocitos vitelogénicos tempranos (O3), ovocitos vitelogénicos tardíos (O4) y ovocitos Maduros (OM). El ciclo de madurez gonadal se dividió en cinco estados según la cantidad y tipo de ovocitos presentes. Los estados 0 y I, corresponden a desovado y previtelogénesis. Los estados II y III a vitelogénesis temprana y vitelogénesis intermedia, mientras el estado IV corresponde a madurez avanzada. La presencia de ovogonias y ovocitos previtelogénicos junto a ovocitos completamente maduros en el estado de madurez avanzada, refleja la capacidad de esta especie de realizar ciclos consecutivos de madurez en intervalos cortos de tiempo. Palabras claves: Palaemonidae, Cryphiops caementarius, ciclo ovárico, madurez gonadal, ovocitos, Chile. Histological description and characterization of the ovarian cycle ofCryphiops caementarius (Molina, 1782) (Decapoda: Palaemonidae) ABSTRACT. Its indiscriminate extraction and alterations of its natural environment, has put in danger of extinction the only commercial freshwater Palemonid present in Chilean inland waters. Even though this situation has awakened interest in studies which allow its controlled reproduction in captivity, currently little is known regarding basic reproductive aspects of this species. Given its relevance, this work describes and characterizes the whole ovarian cycle of Cryphiops caementarius, based on changes in external and internal ovarian morphology. Adult C. caementarius females, obtained from Limarí River, were dissected and its ovaries removed and prepared for histological examinations. Fibromuscular tissue divides the ovarian tissue of each lobe into cone-shaped ovarian pouches (Maturation cones), each one containing various steps of oocytes according to the stages of ovarian development. Based on light microscopic observations of cells' sizes, morphology, and staining with H-...

“…For example, Li, Guo, Gan, Wang & Zhao found that lipids improved vitellogenesis and gonad development of crayfish in a study on the effects of different dietary lipid sources on the growth and gonad maturation of pre‐adult female Cherax quadricarinatus . Furthermore, lipids function as an important source of metabolic organic energy for egg development and participate in embryonic tissue formation of the redclaw crayfish (Harrison ; Rodríguez‐González, Hernández‐Llamas, Villarreal, Saucedo, García‐Ulloa & Rodríguez‐Jaramillo ; Rodríguez‐González, Villarreal, García‐Ulloa & Hernández‐Llamas ). In addition, low levels of lipids in the broodstock diet diminish the quality of the eggs (Furuita, Tanaka, Yamamoto, Suzuki & Takeuchi ).…”

In recent years, crayfish aquaculture industry has been developing rapidly in different regions of the world. Crayfish aquaculture is often carried out in dams, lakes and extensive pond systems. There is an increasing demand for crayfish juvenile in aquaculture sector. Therefore, it is important to know which factors affect reproductive efficiency in crayfish. In the present review, factors affecting the reproductive efficiency of crayfish are divided into two main sections, external and internal factors. Dietary lipids, phospholipids, highly unsaturated fatty acids, protein and amino acids, vitamins and carotenoids are important external factors affecting broodstock crayfish reproduction. In addition, various external (i.e. female size, stocking density, temperature, photoperiod, sex ratio) and internal (i.e. endogenous hormones) factors affect the reproductive efficiency in crayfish. This study reviews the present knowledge with the purpose of realizing the factors that are important to reach optimal crayfish nutrition, maturation and reproduction (i.e. pleopodal egg number and quality). This review will particularly be useful for crayfish farmers and crayfish hatchery units.
