## 5 Conclusions  
Considering the evidence of near-term and recently post-partum females, the frequent capture of YOY pups, but low residency of small juveniles in the area, we suggest that the area surrounding Bimini is an important pumping area for tiger sharks. However, based on the available data, this area does not qualify as a nursery area, and it is unclear if traditional 'nursery' areas exist for this highly mobile species. It is more probable that juvenile tiger sharks use expansive nearshore waters, similar to those of the dusky shark, _Carcharhimus obscurus_[8]. Further research, including standardized surveys (i.e., gear construction similar to other surveys in the region), would be required to put the relative abundance of YOY into perspective with other pumping grounds documented in the USA. This is particularly important given the significant connectivity for tiger sharks between The Bahamas, the southeastern USA, and the overall western North Atlantic region. Telemetry also showed that large juvenile and mature female tiger sharks have large areas of space use, frequently crossing international jurisdictions. However, following these large-scale movements, female tiger sharks also showed multi-year fidelity to the area around Bimini. Taken together, our data suggest the area surrounding Bimini, and the broader Great Bahama Bank, is important for tiger sharks in the western North Atlantic. **Supplementary Materials:** The following supporting information can be downloaded at: [[https://www.mdpi.com/article/10.3390/su141610017/s1](https://www.mdpi.com/article/10.3390/su141610017/s1)]([https://www.mdpi.com/article/10.3390/su141610017/s1](https://www.mdpi.com/article/10.3390/su141610017/s1)), Figure S1: Ultrasound images from tiger sharks Galeocerdo cvier sampled near Bimini, The Bahamas.
