Abstract Reproductive tactics and strategies contribute to the persistence maintenance of long-term populations in fish species. Members subfamily Goodeinae are a group small-bodied freshwater with specialized reproduction (viviparity-matrotrophy). They found highlands central Mexico, most them endemic. The aim this study was conduct comprehensive investigation evaluate annual reproductive cycl...

The study focused on the macroscopic, histological, and biometric analysis of European hake females in GSA 17 (Central-North Adriatic Sea). From 2013 to 2015, 976 were collected analyzed monthly. Though spawning conditions found during whole year, trend GSI showed a peak reproductive season from April July 2014 2015. HSI Kn reached highest values September, after peaks. In 2013, these indices d...
