Trade-offs between size and energy reserves reflect alternative strategies for optimizing larval survival potential in rockfish

quence of finite energy reserves.For example, the allocation decision between offspring number and offspring size has been extensively examined (e.g.Smith & Fretwell 1974, Parker & Begon 1986, Elgar 1990, Roff 1992).In this trade-off, size is generally assumed to provide a valid index of fitness, encompassing additional offspring traits of growth, condition, and survival; numerous examples across a broad range of taxa support this assumption (Roff 1992, but see McEdward & Morgan 2001).However, there are other dimensions to offspring fitness besides absolute size, and different
