Energy Utilization In Bay Anchovy And Black Sea Bass Eggs And Larvae Contrasting Ecological Roles, John Wotring Tucker Jr Jan 1983

Energy Utilization In Bay Anchovy And Black Sea Bass Eggs And Larvae Contrasting Ecological Roles, John Wotring Tucker Jr

Dissertations, Theses, and Masters Projects

The objective of this study was a comparison of developmental changes and energy utilization in eggs, unfed larvae, and fed larvae of two marine fish species that both have pelagic early stages, but differ in phylogeny and early life ecology. The bay anchovy (Anchoa mitchilli), a clupeiform, spawns in estuaries and shallow coastal waters. The black sea bass (Centropristis striata striata), a perciform, spawns offshore at 15-50 m depths. Densities of zooplankton eaten by first-feeding fish larvae are normally higher in coastal waters than offshore. An important determinant of survival of larval fishes is their ability to fulfill nutritional requirements …

Climate Scale Environmental Factors Affecting Year-Class Fluctuations Of Atlantic Croaker (Micropogonias Undulatus) In The Chesapeake Bay (Maryland, Virginia), Brenda L. Norcross Jan 1983

Climate Scale Environmental Factors Affecting Year-Class Fluctuations Of Atlantic Croaker (Micropogonias Undulatus) In The Chesapeake Bay (Maryland, Virginia), Brenda L. Norcross

Dissertations, Theses, and Masters Projects

A conceptual life history of the Atlantic croaker (Micropogonias undulatus) identifies the effects of the environment on juvenile recruitment. In a multi-disciplinary approach to modelling, the major effects are investigated, quantified and presented in a flow chart. The model is divided into three sub models, each representing a major component which affects juvenile recruitment. North/south spawning location in the Mid-Atlantic Bight is affected by the bottom water temperature as influenced by the cessation of the summer winds in relation to timing of croaker migration. The pelagic phase is the most critical time in the life history of a larval croaker …
