Summary: We study size-structured population models of general type which have a growth rate depending on size and time. Local existence and uniqueness of solutions have been shown by \textit{N. Kato} and \textit{H. Torikata} [Abstr. Appl. Anal. 2, No. 3-4, 207-226 (1997; Zbl 0931.92024)]. Here, we discuss positivity of solutions and global existence as well as \(L^\infty\) solutions.
