Abstract

Mudskippers are members of the Oxudercidae family and are amphibious fish that are able to spend long periods out of water. In the present study, Periophthalmus waltoni was sampled from Petroshimi and Jafari stations. Three different forms were observed among the samples of two stations. The morphometry of the main traits was also done and according to univariate and multivariate ANOVA tests, there was a significant difference in all traits between the two stations, and the PCA test divided the populations into two groups. Also, according to ANOVA, MANOVA, and PCA statistical tests, sexual dimorphism was observed between males and females. So in three attributes, males had a higher average than females. This can indicate the larger size of males, which they display during the breeding season to attract the attention of females. In order to determine the age, after dissection of the skull, the ear stones were separated and the annual rings were counted and the age of the samples was recorded. In determining the age and growth pattern of the population in both stations, the fishes were in the age range of 1-3 years, and the highest frequency was related to two-year-old fishes. The length, width, and weight of the left otoliths were similar to the right otoliths. Otolith length had a high correlation with total fish length due to the high correlation coefficient r2. The results show that the otolith length can be used to determine the size of the fish
