Growth and Metamorphosis of the Ringed Salamander
… water were observed. Larvae hatched at a mean total length of 11.4 mm and metamorphosed at a mean total length of 65.5 mm. The length of the larval period ranged from 228-258 days. Growth throughout the larval period was constant and best explained by the regression of total length on age in …

Microevolutionary processes in natural populations of the waterstrider Aquarius remigis
… regression to estimate fitness functions for total length and components of body size, and compare these with observed trait distributions. My analysis shows that female-biased SSD in total length is favoured in A. remigis , but evolution of total length is better understood through analysis …

A Comparison Of Otolith Growth To Somatic Growth In Largemouth Bass, Micropterus Salmoides
… marks on the otoliths on a periodic basis. Total lengths and weights were recorded at the times of injection. Fish were maintained either under a natural photoperiod or a 12L: 12D photoperiod. After thirteen months otoliths were removed and examined. The relationships between otolith growth, …

Effects of landlocked alewife introduction on white bass and walleye populations, Claytor Lake, Virginia
… III and IV clearly exhibited an increase in total length following the introduction of landlocked alewives. Age and growth analysis for walleye, white bass, and alewives are given. Condition factors for walleye and white bass are reported by sex, month, and twenty millimeter total length …

The biology and macroparasites of the sixgill sawshark Pliotrema warreni
… measurements were collected including mass, total length, standard length, girth, rostrum length, interoccular to pre-caudal length, first dorsal origin to second dorsal origin, first dorsal origin to pre-caudal origin, and mouth width. The equation for mass (g) vs. total length (mm) was …

Fungal Control Methods, Diets and Water Temperatures Used to Culture Paddlefish, Polydon spathula
… 40 days after swim-up. Average survival rate and total length of paddlefish fed W-7 hourly were 16.0% and 30 mm, those fed W-7 three times daily were 10.0% and 23 mm, and those fed Liv hourly were 7.5% and 23 mm. The W-7 diet fed hourly was significantly better in terms of survival (P<0.1) and …

Food Selectivity of the Black Bullhead (Ictalurus melas, Rafinesque) in Lake Poinsett, South Dakota
… Two hundred twenty young-of-the-year (37-87 mm total length) fed primarily on limnetic cladocerans and copepods. Leptodora and Diaphanosoma comprised 86.5% of the total food volume. Chironomid larvae and pupae made up 5.6% of the total. Other benthic organisms and littoral cladocerans together …

Growth, Distribution, and Movement of Northern Pike in a South Dakota Natural Lake, With Sampling Considerations
A total of 702 northern pike Esox lucius was collected monthly on 17 occasions from July 1991 to June 1993 from Lake Thompson, South Dakota to assess seasonal variations in growth and sampling data. Mean length of male northern pike from the 1990 year class increased during the spring and autumn of …
