I'm building a form for a mobile app.
I have two sets of radio-groups using ion-radio. One to select sex of the fish and one to select the fate of the fish after successful catch. I can't get these radio inputs to work with formBuilder.
I get two error messages refenrencing lines 113 and 114 in CatchPage.html. Both are identical except for line number so I'll only put one here.
CatchesPage.html:113 ERROR Error: No value accessor for form control with name: 'catchSex'

after these errors I get

I also get similar error messages for my 'catchFate' radio-group.
HTML snippet from catches.html. Entire .html page can be seen here https://pastebin.com/vKW2vp7F.
<ion-row radio-group [(ngModel)]="catchSexSelection" [ngModelOptions]="{standalone: true}">
<ion-item no-lines>
<h2>Sex</h2>
</ion-item>
<!--FISH SEX-->
<ion-col col-4>
<ion-item no-lines>
<ion-label>
<ion-icon name="male"></ion-icon> Male</ion-label>
<ion-radio value="male" formControlName="catchSex"></ion-radio>
</ion-item>
</ion-col>
<ion-col col-4>
<ion-item no-lines>
<ion-label>
<ion-icon name="female"></ion-icon> Female</ion-label>
<ion-radio value="female" formControlName="catchSex"></ion-radio>
</ion-item>
</ion-col>
<ion-col col-4>
<ion-item no-lines>
<ion-label>Unknown</ion-label>
<ion-radio value="unknown" formControlName="catchSex"></ion-radio>
</ion-item>
</ion-col>
</ion-row>
The entire form with all fields and radio selectors is inside one formGroup.
<form [formGroup]="addCatchForm" (submit)="addToDb()" novalidate>
...Entire form...
</form>

I don't understand why these errors occur. I've defined value attribute inside for each selection and each has the same formControlName. Each is inside the same radio-group.
My login page uses formBuilder and it works fine, but radio inputs are giving me a headache.
I decided to user formBuilder because I might want to use some kind of validation in the future. I just want to get the functionality working and send the data to firebase using addToDb method before going too deep into validation.
What should I do?
