Town currently sit two points above the bottom two as they prepare to welcome mid-table Newport County to Huish Park on Saturday.
Under the guidance of new Interim Manager Neale Marmon, the green and whites will look to extend their gap on the relegation zone this weekend with Fisher targeting strong home form to conclude the campaign.
“Four of those games are at home so we want to try and turn this place into the fortress we know it can be. We have an idea of what we need to achieve, but sometimes if you put a number on it you can get a bit worked up by that so we’re taking it week by week.
“Morale is still high, we’re focused on the job at hand coming this weekend because ultimately we’re in a relegation battle and that’s where our focus lies.”
Fisher was part of a Town side that came away from Rodney Parade with a 6-0 win back in September.
Not spending too long reminiscing about the club’s biggest ever EFL victory, the 28-year-old is anticipating a tough encounter in Somerset.
“We know they’ll have memories of that (game) and they have an outside chance of the play-offs so they’ve got everything to play for and we’ve got everything to play for.
“They’ve had a good couple of cup runs that we’ve all seen but this our place and it’s a nice big pitch and we have our way to approach the game and a game plan that will hopefully deal with everything they throw at us and then some.
“One of the first things Neale said was that we’re focusing on the teams above us rather than teams below us and hopefully that can translate into some more freedom and a bit less anxiety.
“Our situation is still what it is and we haven’t lost sight of that but we’ll keep enjoying our football and hopefully this weekend we can put on a good performance for the fans.”
