CHAPTER 6 noodles.” Immature testes will be pink or cream colored, have a ruffled look to the edges of the tubes, and be located near the backbone. Often, the paired gonads are fused together and look like a single structure. Figure 6- 5: Sexing Roundfish 6-18 1/30/2004
CHAPTER 6 Sexing Sablefish The gonads of sablefish are very different from all other roundfish. They are located directly on the backbone, forward toward the head of the fish. Cut up from the anus to the collar to get a clear view. Alternatively, make a cut down from the lateral line to the belly, just behind the operculum, and then another insertion along the belly to the mid-point. Remove all the other organs from the visceral cavity and peer at the backbone area near the posterior of the cavity to look for the gonad tubes. Both females and males have fleshy smooth tubes which are cream or pink in color. Mature fish have liver colored gonad tubes while immature fish will have nearly seethrough ribbons. There are no reliable differences in color or texture to differentiate between non-ripe males and females. To differentiate between the sexes, probe the gonads lobes apart and count the lobes. Males will have four lobes and females will have two lobes. Be cautious when checking the number of gonad lobes. When mature, the ovaries may have a partial fold through each of the two lobes, giving a false impression of four lobes. Cut across the gonad strands to distinguish the true number of lobes. Also be sure to look at the posterior part of the gonad. The lobes of males are fused at the anterior point of the gonad. Since the lobes will be fused anteriorly, they will always look like two lobes at this location and can be mistaken for female gonads. 1/30/2004 6-19
