“…Ironically, because of the efficacy of this control program, which aims to control populations by killing the filter-feeding sea lamprey larvae before they become large enough to metamorphose into parasitic juveniles and prevents adults from accessing spawning habitat using barriers [14], access to certain life stages of sea lamprey for research purposes has become severely limiting [15,16]. Limited access to sea lamprey for study was recognized as an issue decades ago [17], but early attempts at rearing them were unsuccessful [18]. These limitations have hindered research efforts toward the development of new control tactics (e.g., gene editing [19], "green" pesticides [20], and supplemental controls [21]).…”

Conservation aquaculture provides a means for promoting environmental stewardship, useful both in the context of restoring native species and limiting the production of invasive species. Aquaculture of lampreys is a relatively recent endeavor aimed primarily at producing animals to support the restoration of declining native populations. However, in the Laurentian Great Lakes, where sea lamprey Petromyzon marinus are invasive, the ability to acquire a reliable source of certain life stages would be a significant benefit to those controlling their populations and studying the species. Here, we apply methodologies developed for Pacific lamprey Entosphenus tridentatus restoration to investigate the feasibility of rearing larval sea lamprey under laboratory conditions. In two experiments lasting 3 and 9 months, we tested the effects of different dietary sources and water temperature (ambient and controlled) on the survival and growth of wild-caught larvae. Rearing conditions had no effect on mortality, as larval survival was 100% in both experiments. Growth was significantly affected by water temperature, with the highest average daily growth rates observed at 22 and 15°C (0.14 mm day−1) and lowest at 8°C (0.06 mm day−1). Diets of yeast alone (0.19 and 0.21 g L−1) performed better than those comprising a mixture of yeast and other material when fed 3 times weekly (rice flour, wheat flour, fish meal; 0.19 and 0.32 g L−1). Averaged across the three constant temperatures (8, 15, and 22°C), larvae fed on yeast grew 0.13 mm day−1 and 0.01 g day−1, whereas on yeast + fish meal, they grew 0.09 mm day−1 and 0.01 g day−1. At ambient temperature (4–20°C), larvae fed on yeast grew 0.15 mm day−1 and 0.01 g day−1, whereas those fed on yeast + wheat flour grew 0.13 mm day−1 and 0.008 g day−1 and those fed on yeast + rice flour grew 0.12 mm day−1 and 0.009 g day−1. An experimental duration of 90 days was sufficient to detect significant changes to larval sea lamprey growth stemming from temperature variation. Overall, rearing of sea lamprey in captivity appears feasible at low density (31–32 g m−2 and 17–25 larvae m−2), but uncertainties remain regarding the most appropriate means of providing adequate feed for these fish in high-density conditions.

“…Therefore, a suitable laboratory method of culturing these animals was needed. [4] and the authors (unpublished data) were largely unsuccessful. Lennon placed 92, week-old prolarvae in a large standing water aquarium and had two survivors 20 weeks later'.…”

Hammond Bay Biological Station, Millersburg, Michigan 49759THE GENERAL LIFE HISTORY of larval sea lampreys (Petromyzon marinus Linnaeus) has been described [1, 6]. After hatching, the larvae burrow into the muddy bottom of streams where they ingest plankton, mud, and organic detritus. Sea lamprey larvae live in the mud for several years before they metamorphose into the freeswimming, parasitic stage that feeds on the blood and liquefied tissues of fish.Prior to the discovery of a selective sea lam-
