This report describes the development of the activities carried out at the Itaparica Fish Farm, located in Glória, Bahia, as well as elucidating the importance of each stage. At the endwe suggestimprovements to maintain the good functioning of the productive sector. The main species cultivated in the region is Oreochromis niloticusin net cages. Thisactivity is expanding in the world and also in this region, having as security food security, employment and revenue to the Stateand for the producer. The main activities performed were: Reception and settlement of the animals, feeding, immunization, classification, biometrics, monitoring, and technical visits. These activities were carried out during three months and contributed to broaden and apply the knowledge built throughout the academy, as well as allowing the visualization of different scenarios, also allowing the development of professional and personal relationships that will be indispensable for insertion in the market of job.

Knowledge of the morphometricand reproductive aspects of Macrobrachiumamazonicum(HELLER, 1862) is a basic toolfor the elaboration of adequate management, conservation and exploitation strategies. The objective of the present study was to study the morphometricand reproductive aspects of M. amazonicumin the Cachoeira II reservoir, located in Serra Talhada, a mesoregion of the Pernambuco sertão. The prawns werecollected monthly between June 2016 and May 2017. From the morphometric measurements the relative growth was analyzed and classified as allometry. A macro and microscopic analysis atovaries was performed to classify the maturational stages and estimated the size of the first maturation. A total of 432 specimens (86 males and 346 females) were sampled. The sex ratio was statically different from 1: 1 in all months, in favor of females. The reproductive period of the studied population was continuous, with annual reproductive peaks between September and November beyond February, corresponding to the period of rainfall. Thefecundity ranged from 128 to 2724 eggs, being related to the size of the females. The largest specimen captured was male, measuring 87.13 mm, against 80.63 mm of the opposite sex.Six stages of development were found: immature, developing, developed, spawned in development, spawned and rested. Based on these analyzes the size of the first maturation of the females was identified in 9.46 mm of cephalothorax length and,soon,suggested as the minimum size of capture.
