Hippoglossoides Platessoides

Fecundity estimates were made on a total of 140 mature American plaice from the southern and northern slopes of the Grand Bank and from St. Mary's Bay. Log–log relationships were established between fecundity and fish length, gutted and gilled weight, age, and ovary weight. No differences were found to exist between the fecundity–length relationship of plaice from the three areas, but there is a suggestion that within areas there may be annual differences in egg production. At comparable ages plaice from the southern slope of the Grand Bank are larger in size and produce more eggs than those from the northern slope and St. Mary's Bay.

Abstract The objective of this study was to evaluate the probiotic action of two bioadditives and their behavior on the bioproductive parameters and histomorphometric changes of CoBB-500 chickens, in the first 21 days of age. 450 Cobb-500 chicks were used, distributed in three groups of 150 animals each. Control (T1); microbial culture A (T2) and microbial culture B (T3). Substrate T2 (molasses-vinasse) fermented with Lactobacillus acidophillus, L. bulgariccus spp. T3 (molasses-vinasse) fermented with Saccharomyces cerevisiae and Kluyveromyces fragilis (L-4 UCLV). A completely randomized design was used to evaluate live weight, mean daily gain, diarrheal incidence, mortality, relative weight of the digestive tract organs, and histomorphometric changes. In the evaluations carried out at 21 days of age, the weight gain in the chicks that consumed biopreparations (T2 and T3) was higher (P> 0.05). Chickens that consumed biopreparation did not die during the study. The relative weight of the digestive tract organs was higher (P <0.001) in treatments T2 and T3. The length and width of the villi were better in groups T2 and T3 (P <0.05), the depth of the crypts was greater (P <0.05) in T1. Regarding the depth / length relationship of the villi T2 and T3 it was better (P <0.05). It concludes that the inclusion of biopreparations in chicken feed improves weight gain, development and growth of organs of digestive importance. Likewise, a reduction in the occurrence of diarrhea and animal mortality is achieved.

We assessed the fish length – otolith length relationship (FL–OL) in Dolly Varden (Salvelinus malma malma) to verify proportional growth. A decoupling was detected during first ocean migration where fish growth was occurring at a greater rate than otolith growth. Because of this decoupling, the application of traditional back-calculation models overestimated the size-at-age in premigratory char. We developed modified back-calculation equations from existing traditional models to account for this decoupling based on discontinuous piecewise regressions. The new biological intercept breakpoint method (BI–BP) provided the most accurate representation of fish size-at-age throughout all life history stages when compared with known size-at-capture values in fish. The decoupling indicates that factors other than somatic growth are important for otolith accretion. Physiological changes during smoltification likely alter calcium uptake and thereby affect calcium deposition rates on otoliths during this short but biologically critical time period of life history. It is probable that species exhibiting similar complex ontogenetic shifts in life history will likely exhibit decoupling to some extent in the FL–OL relationship.

Otolith Size

Relationships between fish length and otolith length, width and mass were examined in the Australian anchovy Engraulis australis (White, 1790) recovered from the food of Gannet examined from colonies at islands of Horuhoru Rock and Mahuki Islands in the Hauraki Gulf, New Zealand. The relationships between otolith length- fish total length (TL), otolith-weight-TL, and otolith-width-TL were investigated by means of non-linear regression models (TL = 0.54 OL 16.86, TL = 4.39 OW 7.61 and TL = 26.19 OWe 2.2). This study characterizes the first reference available on the relationship of fish size and otolith size and weight for E. australis obtained from bird’s food in the Pacific Ocean region
