The field collected snails were segregated according to the size (shell length, in mm), and the frequency distribution of each size class was estimated. Subsequently, each size class was reared in the laboratory with continuous monitoring for the deposition of the eggs in the rearing terrarium for a period of six weeks using three replicates per size class. The growth rate of each species was highest in the smallest size class and declined gradually with the increment of shell length. The shell lengths of A. gracile and S. daucina at sexual maturity were 4–5 mm and 6–7 mm, respectively, and fecundity was positively linked with the size (shell length). G. gemma did not oviposit, except that the large size-class had given few small offspring. The results showed that growth and reproduction of three species varied significantly with size classes, which reflects the ability for these snails to colonize and establish in favourable habitats in short time period.","PeriodicalId":168859,"journal":{"name":"Invertebrate Reproduction & Development","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121521801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aimed to determine the effects of the cocoon incubation angle (CIA) on hatching success in hirudiculture, using leech species of Hirudo verbana. Cocoons were individually incubated in jars at three different angles, horizontally (0°), angled (45°), and vertically (90°) for one month. The rot in cocoons, which was 17.5% in cocoons incubated horizontally, decreased gradually as the CIA increased, was 2.5% in cocoons incubated vertically. The average number of offspring obtained from cocoons increased as the CIA increased. The optimum CIA was determined to be 78.73° and 60.63° for the lowest rot in cocoons and the highest number of offspring, respectively. The present study revealed that although not statistically significant the CIA is a variable affecting the hatching success of medicinal leeches during the incubation period. This result is thought to be because the air ventilation inside the cocoons is more efficient in cocoons positioned at an angle or in a vertical position compared to cocoons incubated in a horizontal position. For profitable hirudiculture, we recommend that cocoons be positioned at an angle close to vertically, more than 60° during incubation.","PeriodicalId":168859,"journal":{"name":"Invertebrate Reproduction & Development","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132653889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 175 specimens of F. ibiapaba were analysed. The onset of morphological sexual maturity was estimated at 31.7 mm for males, and at 35.2 mm for females. We observed sexual size dimorphism in CL and PLW, with females larger than males. Positive allometry of cheliped variables was observed in juvenile and adult males, while females showed positive allometry of PLW in juvenile and adult. Finally, the growth of the variables was different between adults and juveniles in both sexes. The ecological information obtained in our study is unprecedented for the genus Fredius. The sexual size dimorphism with females larger than males, probably resulting from their reproductive biology. Additionally, the energy expenditure in cheliped growth in males, may be associated with success during agonistic disputes and the use of these structures to position females during copulation, since they are larger in body size.","PeriodicalId":168859,"journal":{"name":"Invertebrate Reproduction & Development","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127648171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The size of ovigerous females, as well as the fecundity values, egg volume, internal volume of occupied shells, and reproductive effort were analysed, and the results evidenced significantly higher values for females of both species collected in SE localities. In females collected NE, there was also the presence of aberrant eggs, which influenced the reproductive parameters analysed for these species, resulting in lower reproductive effort. Biomass invested in egg production varied between populations, but ovigerous females of SE invested a higher percentage of their weight in the production of its egg mass, showing significant differences in the reproductive effort. Variation in reproductive performance detected for both species may be related to latitudinal location and associated to the habitat’s characteristics.","PeriodicalId":168859,"journal":{"name":"Invertebrate Reproduction & Development","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128141737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Testosterone (T), various oestrogens, and progesterone have been reported in this group of organisms and the amounts of these hormones have been correlated with seasonal variation and reproduction. Yet, neither the role nor the origins of sex steroids are fully clarified. Thus, we tested the hypothesis that, apart from the esterification process, the aromatisation of androgens to oestrogens can help balance T levels during gonadal development in both sexes using Mytilus edulis trossulus as a model species. The highest testosterone concentrations were found in developed male and female gonads (IV reproductive stage of gametogenesis). The highest aromatisation efficiency was also found in the developed male and female gonads, but also in the gills. During the other stages of gametogenesis (II, III, V-I), a decrease in both testosterone concentration and aromatisation efficiency was observed in the gonads of males and females, as well as in the gills of males. However, the decrease in testosterone concentration did not affect the 17β-oestradiol concentration in mussel tissues. Thus, together with the esterification process, the ongoing aromatisation in bivalve tissues may help keeping balanced T levels.","PeriodicalId":168859,"journal":{"name":"Invertebrate Reproduction & Development","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133910420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, sperm counts of broodstock fed BD (11.70 × 106 ±1.05 × 106 per spermatophore) and those fed diets supplemented with polychaete extracts were significantly higher compared to that fed with control fresh diet at 0.73 × 106± .09 × 106 (p = 0.001).

Inclusion of TSF (0.25–1.00%) significantly increased the spermatophore crude protein content of broodstock compared to those fed with other diets (p = 1.20 × 10−5).
